Each user of the hard disk is depositing a lots of useful data, and hard disk is a easy go wrong components. In order to effectively keep the data in the toshiba satellite l675-076 laptop cpu fan hard drive, in addition to effective preservation of the hard disk data, backup job beyond, learn to be in hard disk failure how to life hard disk, or extract the useful data, the loss to the minimum.
1, the system does not recognize hard disk
This kind of failure is common, that is, from hard disk can't start, from A disk boot cannot enter the disk C, use CMOS of automatic monitoring function also is unable to find the existence of the hard disk. This kind of fault are mostly appeared in the connecting cable or IDE mouth port, hard disk itself failure rate is very few, can pass to plug hard disk cable or change the IDE mouth and cable replacement test, but soon found toshiba satellite l655d-12k laptop cpu fan fault is. If the new grafted in hard don't admit that there is a common reason is that the hard disk master-slave line, if hard disk joint in the IDE Lord disc position, the hard disk must jump is given priority to disk, jump line error cannot generally be detection to hard disk.
2, CMOS fault caused by the
CMOS correct or not directly affects the normal use of hard disk, here refers to the type of hard disk. Now that the machines are support "IDE auto detect" function, can automatically detect the type of hard disk. When connecting a new hard disk or replacement of the hard disk will be after through this function to set up the type. Of course, now some types of mainboard can automatically identify the type of hard disk. When hard disk type mistake, sometimes simply can't start system, and sometimes can start, but will happen error, speaking, reading and writing. The hard disk type such as CMOS is less than the actual hard drive capacity, the hard disk behind the sector will be unable to read or write, if it is multiple partitions status is individual partition will be lost. There is another important toshiba satellite l650d-101 laptop cpu fan failure cause, because at present IDE support logic parameter type, hard disk can use Normal, LBA, Large, etc. If the general mode installed the data, and in the CMOS changed to other pattern, will happen the hard disk read and write fault, because its physical geological mapping relationship has changed, will not be able to read the original correct hard disk position.
3 and the Lord direct program causes start-up failure
The Lord of the hard disk boot sector of the hard drive is the most sensitive one components, one of the master boot program is a part of it, the segment of a program, is mainly used to test the correctness of the hard disk partition, and determine the active partition, responsible for the guide right over to the active partition DOS or other operating system. This section program will not damage from the hard disk guide, but from soft area or light area of hard disk after reading. Repair the fault of the methods are simple, use high version of DOS fdisk the most convenient, when band parameter/MBR run time, it will directly replace (rewrite) hard disk master boot program. In fact the Lord of the hard disk boot toshiba satellite l650d-03j laptop cpu fan sector is the program to create, fdisk. Among the exe features a complete hard disk master boot program. Although DOS version constantly updated, but hard disk master boot program there has been no change, from DOS 3. X that there is winDOS 95 DOS, so as long as find a DOS boot disk boot system and run the program can repair. In addition, as kv300 and other tools software also has this function.
4, partition table error guiding start-up failure
Partition table error is hard disk of serious mistakes, the degree of different error can lead to different loss. If there is no active partition mark, then the computer could not be started. But from soft area or light area after the guidance system of hard disk, speaking, reading and writing, but through the fdisk reset active partition for repair. If it is a partition type error, can cause the loss of a partition. Partition table on the fourth bytes for partition type value, normal guidable more than 32 MB of basic DOS partition value for 06, and extended DOS partition value is 05. If the basic DOS partition type to 05 cannot start system, and can't read and write the data. If the 06 to DOS not to know other types such as efh, the DOS think changed zoning not DOS partition, of course, can't, speaking, toshiba satellite l650-0dn laptop cpu fan reading and writing. Many people use this type of value to realize a single partition encryption technology, back into the right type of value can make the partition returned to normal. The partition table and other data used to record partition starting or terminate address. These data will cause damage to the partition of chaos or missing, generally unable to manual recovery, the only way is to use backup partition table data to write back, or from any other of the same type and the same hard disk partition condition get partition table data, otherwise will lead to other data permanent loss. In the master boot sector for operation, can use nu tools such as software, the operation is very convenient, can be directly to the hard disk drive master boot sector for reading and writing or editing. Of course also can use debug to operation, but the operation trival and has certain risk.
5, partition effective mark error caused by the hard disk failure
In the hard disk master boot sector there are still an important part, that is the last two bytes: 55 aah, this word is a useful indicator of the sector. When from the hard drive, floppy or light area which, when activated, will test the two bytes, if present, think it is hard disk exist, or will not admit that hard disk. This symbol from hard disk boot will turn into ROM basic or tip into the floppy disk. From the floppy disk boot can't turn into hard disk. Here can be used to the hard disk encryption technology. Can use toshiba satellite l650-02b laptop cpu fan debug method recovery processing. In addition, the DOS boot sector is still have such marks exist, when the DOS boot sector without guide sign, the system startup will show: "missing are automatically notified". The repair methods can use Lord boot sector repair methods, just address is different, more convenient method is to use the following DOS system general repair methods.
6, DOS guidance system caused by the start-up failure
DOS boot system mainly by the DOS boot sector and DOS system files composition. System files including iosys, msdos. Sys, command.com, including command.com is DOS shell file, usable and other similar documents to replace, but by default is DOS startup the necessary documents. In Windows 95 carry DOS system, msdos. Sys is a text file, is to launch Windows must file. But only start DOS can need not this document. But the DOS boot when something goes wrong, from the floppy disk or CD guidance system, and then use sys c: transfer system can repair failure, including the boot sector and system files can be restored to normal condition.
7, fat table caused by the fault, speaking, reading and writing
Fat table records the hard disk data memory address, each file will have a set of connection of fat chain designated the deposited cluster address. Fat table damage means the loss of the contents of the documents. The good news is DOS system itself provides two fat table, if the current use of fat table is damaged, it can be the second to cover repair. But as a result of different specifications of disk its fat table and the length of the two fat table address is not fixed, so must be correct repair find its correct position, by some tools software such as nu etc itself has such repair function, use is very toshiba satellite l645-s4026 laptop cpu fan convenient. The debug also can realize the operation, namely USES the m ordered the second fat table moved to toshiba satellite l675d laptop cpu fan the first table place can. If the second fat table also damaged, it also can't take hard disk restored to the original state, but the file data still stored in hard disk data area, can use CHKDSK or scandisk command repair, and ultimately the *. CHK files, this is lost fat chain sector data. If it is a text file can be extracted from it and can merge complete file, if it is binary data files, it is hard to recover the full file.
8, list damage caused by the guide fault
List record the document's filename in the hard disk data, of which the most important one is the file starting cluster number, list since there is no automatic backup function, so if directory damage will lose a lot of documents. A kind of reduce the loss method is also used the above CHKDSK or scandisk program method, from the toshiba satellite l645-s4026 laptop cpu fan hard disk, search out CHK file, the list when damage is the first cluster number is missing, in fat for damaged cases by the formation of the CHK file usually relatively complete file data, each CHK file is a complete file, its instead of the original name can restore most file.
9, error when deleted partitions data recovery
When using fdisk deleted after hard disk partition, the surface phenomenon is the hard disk data has completely disappeared, in has not formatted in hard disk will be displayed invalid drive. If know fdisk work principle, will know, fdisk just rewrite the hard disk master boot sector (0 level 0 way 1 sector) the content. To be specific, delete the hard disk partition table information, and hard disk partition of any of the toshiba satellite l645-s4026bn laptop cpu fan data are not change, can imitate the partition table wrong repair methods, i.e., trying to restore partition table data can restore the original partition namely data, but it only in addition to partition or reconstruction after the partition. If have partition with format formatting, earlier recovery after division, in according to the following method restore partitioned data.
10, false to format the hard disk data recovery
In the DOS high version condition, formatting operation format in the default state have established the used to restore format disk information, is actually the disk the DOS boot sector, fat partition table and list all the content to the disk copy last few sector (because the back of the sector rarely used), and the toshiba satellite l640-02v laptop cpu fan contents of the data area did not change. So through the operation "unformat c:" can restore the original file distribution list and list, and then the hard disk information recovery. Another DOS also provides a miror command used to record the current disk information, for formatting or delete the recovery of after use, this method is more effective.

Facebook commentary will ruin Twitter can continue to live
Forbes published online today signed for (Rocco Pendola), the paper said Twitter due to their own is according to the content changes, its not like Facebook that need to actively carry out reform. And Twitter 140 words content restrictions also enhance the content quality and attractive.
The following is the main content:
As the United States rock stars (Bruce Springsteen) in the song "Atlantic city (sing:" now everything has fallen away, this is a fact. But maybe one day everything will rise again."
Facebook want to attract investors, we have to "to draw a makeup", to reform.compaq presario c702tu laptop keyboard While Twitter have no such distress, the company now the state is pretty good, do not need in rectification.
I think, Facebook will ruin, and even, will repeat mistakes of the MySpace, and will be another things resurrection. This kind of thing is indeed happened in the newspaper industry, in addition to the extremely individual press outside, the newspaper industry has decline, and with Twitter this form rebirth.
You may not realize this, perhaps is not often use Twitter, but Twitter is the modern version of the newspaper, and will continue to survive in this way.
I always put my intelligent mobile phone on the side of the bed, when I woke up in the middle of the or wake up in the morning, I'll spend 5 to 10 minutes browsing Twitter, and, after that, I'll brush on all day.
If want to quickly understand what's happening now everything, from your own backyard to the other side of the earth, there is compaq presario c703la laptop keyboard no better way the Twitter. If you want to further understand the news, whether now or later, can through the Twitter mobile and desktop client, or TweetDeck such development program, simplify the process of understanding.
And other service type, Twitter is also a kind of entertainment. If you choose to accept, Twitter can help you self promotion.
Twitter will never disappear, whether style or "appearance", not like that Twitter Facebook self evolution, because, as long as the content change, Twitter in variable. In fact, Twitter can and has been in an instant with change.
On Facebook users do anything, in the Twitter also can do it, and Twitter things compaq presario c703tu laptop keyboard really practical, boring trifles and less.
This is because the user can focus on Twitter on others, and these focus on the user's writing micro bo Twitter and Facebook users are popular content than "good friend" published information life a lot more fun.
Choose a interest, choose a hobby, think about your passion, understand oneself are engaged in industry, pay attention to the right person, interact properly. Twitter users from several aspects to improve the quality of life and experience.
There is no Twitter is more practical social media website. Besides professional networking sites LinkedIn, unless the user unemployment, or is to apply for a job, also or to do some specific network activities, otherwise, the user use LinkedIn way and the Facebook.
Twitter compaq presario c704tu laptop keyboard 140 words content restrictions enhance the content quality and attractive, let the most intelligent people to have breakthrough. In fact, Twitter happened to one of the worst thing is long micro bo TwitLonger applications appear. If users need to more than 140 words to fully express their own ideas, can use TwitLonger. But this makes Twitter to Facebook direction tilt, reduce the Twitter quality.
Facebook is a sustainable trend. In other words, its service in a purpose. The future of Facebook have than those who have it both ways of critics think more light. However,compaq presario c705la laptop keyboard from any reasons, Facebook will never be Twitter, whether it be practical, or IPO (initial public offering) the smooth transformation, as long as the Twitter in the listing is not the apple before purchase.
I said Facebook will die, it refers to the five years, 10, 15 years may be 20 years later. Twitter of real-time,compaq presario cq35 laptop keyboard relevance and popular with young audience welcome, these are all television news network sublimity that.
If Twitter cannot through these characteristics profits, it will need to immediately from LinkedIn there looking for better sales personnel.

F1 - add function key role is introduced
Typewriter keyboard and computer keyboard fujitsu lifebook e8210 laptop keyboard one of the biggest different is the keyboard the top row key, F1 to add, they are usually called quick function key. These key in the past DOS system is very practical, but in today's Windows operating system, without these key we can still normal use a computer, but master to F1 can add more convenient and flexible to improve work efficiency, this is also a computer high hand must master. The keyboard respectively on the 12 key for everyone to do a detailed introduction, hoping to be helpful to you.
F1: in the DOS operating system, you will find that press the F1 will usually appear help options, the Windows operating system, if you are in a selected program press F1, help also will often appear. If it is not in any program, but in the explorer or desktop, then press the F1 will appear Windows help program.fujitsu lifebook e8110 laptop keyboard If you are in a procedure carries on the operation, and want to get Windows help, need to press Win + F1. Press Shift + F1, can appear "What 's This?" Help information.

F3: in the explorer or desktop press F3, can appear the "search document" window, so if you want to a folder on the document to search, so direct press F3 key can quickly open the search window, and the scope of the search has default Settings for this folder. Similarly, in Windows Media Player press it, there will be "through the search computer fujitsu lifebook d8800 laptop keyboard added to the Media library" window.
F4: F4 have some very practical function, when you are IE work, can use this key to open the IE address bar list, at the same time, you can also use Alt + F4 combination key close your current work window.
F5: the F5 break key to refresh IE or explorer in the content of the current window.
This is a very convenient shortcut key fujitsu Amilo Mini Ui 3520 laptop keyboard, when you insert a new floppy disk is, your screen display is still before the contents of one floppy disk, only need to press F5 break once the screen can see just insert floppy disk content.
F6: can quickly in the explorer and IE address bar to the position.
F7: in Windows without any role in individual program may have effect. But in DOS window, it is useful, give it a try!
F8: in start the computer fujitsu lifebook d6680 laptop keyboard, can use it to display the boot menu. Some computers can also in computer start first press this key to rapid decruitment startup Settings menu, it can be quick select is floppy disk boot, or cd-rom start, or directly with hard disk boot, you don't have to go to the expense of enter BIOS to boot sequence changes. In addition, still can install Windows in accepting the installation of Microsoft agreement.
F9: in Windows also does not have any effect. But in the Windows Media Player which can be used to reduce the volume quickly.
F10: used to activate Windows or application menu, press Shift + F10 will appear right shortcut menu. And in the keyboard Application key role is the same. And in the Windows Media Player, its function is to raise the volume.
F11: in Windows work, press the F11 can make the fujitsu lifebook b3020d laptop keyboard IE or explorer into full screen mode. Can make the menu bar disappear, so that we can see on the screen more information, again press can restore.
Add: in Windows also does not have any effect. But in the Word, press it will fast popup save as document window.
Many programs support function key combination, the most commonly used key combination is Shift + a, Alt + a, and Crtl + a, these key combination is very practical, such as in MS word, elected the fixed one paragraph is, press Shift + F3 will selected paragraph into capital.

The notebook computer CPU choice
CPU as the sign of computer development, had been under the attention of people.
Whether desktop computer or notebook computer samsung r528 series laptop cpu fan, people when the choice must first consider the CPU is what kind of. Because of Intel violent advertisement publicity, the Chinese idea of computer mark is Intel CPU.
In the past, CPU speed on the performance of the whole computer plays a vital role, with the development of technology, the machine performance bottleneck is no longer the CPU. The same class CPU in performance won't have very big difference, such as Intel 1.6 GHz CPU and 1.7 GHz CPU for an ordinary users it reflects performance won't be a big difference, perhaps simply can't feel it change, more than a memory to improve the performance of the effect is good.
0.1 GHz for user machine performance won't have greatly improved, but manufacturer merchants will take it as a big selling point, often in the price, will be more than one hundred yuan or hundreds of yuan even nearly one thousand yuan. In the machine when the choice, CPU only choice as a standard, for the CPU samsung r540 series laptop cpu fan speed without overstretch, in the same class last in line. Because still need to consider the price. Avoid "big horse car" the waste of resources.
In our impression, both desktop computer or notebook computer, the CPU choice, there is no doubt that Intel is first selection. Indeed, Intel in these respects do very good, also because of its excellent cover our eyes, only see its shining point.
In fact, we ignore many excellent products, for example, AMD CPU, transmeta CPU, VIA CPU. They have distinguishing feature each, and Intel together share the processor this huge market.
AMD is the first laptop computers launched 64 - bit CPU samsung r560 series laptop cpu fan, and AMD CPU has high performance-to-price ratio. Transmeta although launch soon, but because of its unique processing mode and low voltage power consumption performance of low quantity of heat quickly application in light ultrathin laptop computers. SONY C1 series is the most classical application. VIA "Chinese core" -- han who processor, although there is no one like Intel, AMD so powerful processing function, but its low calorific value is low-end notebook computer the best choice.
In addition to special CPU used in laptop computers beyond, still some manufacturers association use desktop computer CPU samsung r580 series laptop cpu fan. For the current technology to do so is feasible, because laptop and desktop computer difference is that the problem of heat and power consumption. If can solve the problem of heat and power consumption, the price will and use special CPU notebook computer a slightly different, for user is beneficial. The most important thing is not to be deceived by illegal dealers, the desktop CPU notebook when special CPU notebook.
The desktop CPU notebook samsung r60 series laptop cpu fan whichever manufacturers, in common is a bit thick, a little heavy, one-sided said the only way to guarantee the stability of the system. Another characteristic is its working current, he was in the COMPAQ EVO N1000V speaking, it USES is desktop Pentium 4 2.0 CPU, power adapter output rated voltage of 18.5 V (belong to normal), rated current 4.9 A (belong to higher). So, a use desktop computer CPU notebook computer rated power nearly 100 w, and use special CPU notebook computer rated power to more than 60 w.

In the past, CPU speed on the performance of the whole computer plays a vital role, with the development of technology, the machine performance bottleneck is no longer the CPU. The same class CPU in performance won't have very big difference, such as Intel 1.6 GHz CPU and 1.7 GHz CPU for an ordinary users it reflects performance won't be a big difference, perhaps simply can't feel it change, more than a memory to improve the performance of the effect is good.
0.1 GHz for user machine performance won't have greatly improved, but manufacturer merchants will take it as a big selling point, often in the price, will be more than one hundred yuan or hundreds of yuan even nearly one thousand yuan. In the machine when the choice, CPU only choice as a standard, for the CPU samsung r540 series laptop cpu fan speed without overstretch, in the same class last in line. Because still need to consider the price. Avoid "big horse car" the waste of resources.
In our impression, both desktop computer or notebook computer, the CPU choice, there is no doubt that Intel is first selection. Indeed, Intel in these respects do very good, also because of its excellent cover our eyes, only see its shining point.
In fact, we ignore many excellent products, for example, AMD CPU, transmeta CPU, VIA CPU. They have distinguishing feature each, and Intel together share the processor this huge market.
AMD is the first laptop computers launched 64 - bit CPU samsung r560 series laptop cpu fan, and AMD CPU has high performance-to-price ratio. Transmeta although launch soon, but because of its unique processing mode and low voltage power consumption performance of low quantity of heat quickly application in light ultrathin laptop computers. SONY C1 series is the most classical application. VIA "Chinese core" -- han who processor, although there is no one like Intel, AMD so powerful processing function, but its low calorific value is low-end notebook computer the best choice.
In addition to special CPU used in laptop computers beyond, still some manufacturers association use desktop computer CPU samsung r580 series laptop cpu fan. For the current technology to do so is feasible, because laptop and desktop computer difference is that the problem of heat and power consumption. If can solve the problem of heat and power consumption, the price will and use special CPU notebook computer a slightly different, for user is beneficial. The most important thing is not to be deceived by illegal dealers, the desktop CPU notebook when special CPU notebook.
The desktop CPU notebook samsung r60 series laptop cpu fan whichever manufacturers, in common is a bit thick, a little heavy, one-sided said the only way to guarantee the stability of the system. Another characteristic is its working current, he was in the COMPAQ EVO N1000V speaking, it USES is desktop Pentium 4 2.0 CPU, power adapter output rated voltage of 18.5 V (belong to normal), rated current 4.9 A (belong to higher). So, a use desktop computer CPU notebook computer rated power nearly 100 w, and use special CPU notebook computer rated power to more than 60 w.

CPU level 2 cache capacity
CPU Cache (Cache Memoney) is located in between CPU gateway mx6438 laptop cpu fan and memory of the temporary memory. Its capacity than the memory is small, but exchange faster. The data in the buffer, only a small part of memory data, but it is a small part of the short time CPU will visit, when the CPU call a large number of data, it can avoid the memory cache call directly from, so as to speed up the reading speed. Thus it can be seen, the CPU to cache, it is a kind of efficient solutions. In this way, the whole internal memory (cache + memory) becomes a cache of both high speed and memory of the large capacity storage system. The cache to CPU performance influence. Mainly because of the CPU's data exchange between order and CPU and cache the bandwidth of the cause.
The working principle of the cache, is when the CPU to read a data, the first from the cache find, if found, immediately read and gave CPU processing; If not found, with the relatively slow speed from memory and CPU gateway mx6440 laptop cpu fan processing to read, but at the same time, the data in the data block to tune in to the cache, can make later to block the data read from the cache, don't have to call memory.
It is such a read mechanism, make the CPU reads cache hit is very high (most of the CPU can be up to 90%), that is to say, the CPU next to the data read 90% are in cache, only about 10% need to read from memory. This will save the CPU directly read memory time, also make the CPU reads data without waiting for basic. Generally speaking, the order of the CPU reads the data, is first cache, after memory.
The earliest first CPU gateway mx6447 laptop cpu fan cache is a whole, and capacity is low, Intel Pentium era from the start, the cache are classified. At that time the CPU integrated in the kernel of cache has not enough to meet the needs of the CPU, and manufacturing process limit, also cannot greatly improved the capacity of the cache. So there was a integrated in the same block with CPU board or on the main board of the cache, at this time, the CPU kernel integrated cache, called level cache. And external called level 2 cache. Level 1 Cache, still score according to the Cache (Data Cache, D - Cache) and Instruction Cache (Instruction Cache, I - Cache). Respectively used to store data and execute these data's instructions, and both can also be CPU access, reduce the contention Cache caused by the conflict, improve the efficiency of the processor. Intel Pentium 4 launched in processor, there are also a kind of level tracking cache, capacity of 12 KB.
With the development of the CPU manufacturing process, level 2 cache can also easily integrated in the CPU kernel, capacity are also ascending year after year. Now again with integrated the CPU internal or not to define a, level 2 cache, has not exactly. And as a level 2 cache is integrated into the CPU kernel, the previous level 2 cache and CPU gateway mx6448 laptop cpu fan big gap crossover situation was also change, at this time with the same in the main frequency speed work, can for CPU provide higher transmission speed.
Level 2 cache is one of the keys to CPU performance. The CPU core the same circumstances, increase level 2 cache capacity, can make the performance improved. And the same core CPU of high and low end points, and often is in level 2 cache on the difference. Thus it can be seen, level 2 cache for the importance of CPU.
CPU in the cache find useful data are called "hit", when no CPU gateway mx6450 laptop cpu fan cache the data (then called not hit), the CPU to access memory. Theoretically, in a have a level 2 cache CPU, read the first shot 80% in the cache. That is to say, CPU level cache find useful data, accounting for 80% of the total data, and the rest 20% from level 2 cache read. Because can't predict accurately the will execute data, level 2 cache read from around 80% (from the level 2 cache read useful data according to the total of 16%). So, and data from memory will have to call, but this is a very small proportion of the. The higher the CPU, will also carry level 3 cache, it is to read after level 2 cache misses data design - kind of cache, in has level 3 cache CPU, only about 5% of the data from memory to call, further improve the efficiency of the CPU.
In order to ensure access to CPU gateway mx6453 laptop cpu fan has higher percentage, the contents of the cache should according to certain algorithm to replace. A more commonly used algorithm, is "least recently used algorithm" (LRU algorithm), it is a recent period of at least be visited out line. Therefore, the need for each line set a counter, LRU algorithm is the hit done counter reset, and other various counter add 1. When there is the need to replace, eliminated line counter attribute the maximum data line out. This is a kind of high efficient, scientific algorithm. The counter reset process, can put some frequent after call don't need the data out in the cache, improve the utilization rate of cache.
CPU gateway mx6629 laptop cpu fan products, the capacity of the basic level cache in 4 KB to 64 KB between, level 2 cache capacity is divided into 128 KB, 256 KB, 512 KB, 1 MB, 2 MB, etc. Level 1 buffer capacity, each between products differ not quite, and secondary buffer capacity, it is the key to improve the CPU performance. Level 2 cache capacity of ascension that is determined by the CPU manufacturing process, capacity increase will inevitably lead to the increase of the number of CPU internal transistor, in limited CPU area integrated more cache, in the manufacturing process of the higher demands.

Ink jet printer to have suitable working environment
Ink jet printer just buy back day,asus u50f series laptop cpu fan everybody will be talking about it with care, everyday want to wipe ash, when using carefully, need not when also can with beautiful table cloth make it protected; While not a few days, many people have no protection ink-jet printer, little imagine ink-jet printer in the lack of "love", its working performance are also "gradually with gradually low". We should give the inkjet printer to find a "feng shui good" position put, also spray play a suitable working environment.
1, do not let the spray play and host sharing power
The author suggest you users, in not as a last resort, had better not let inkjet printer source is connected to and host connected power supply socket, this is because now the market sales of ink-jet printer, and not every a computer users must use equipment, now there are many new ink-jet printer model often do not have a power control switch, only a jack; So, if you use cable will printer connected to and host sharing power board, switch on the power socket, ink-jet printer will also connect the power, and the asus g72gx series laptop cpu fan hypothesis and we don't want to use ink jet printer words, can cause the wasted. Moreover, ink-jet printer in every opening or closing the power supply, printer will be cleaning the print head and initialization printers, ink conveying system for filling ink, of course, want to waste some ink, it's "a drop of ink a penny" ah, Perhaps you will say, ink-jet printer have energy saving protected mode ah, but often frequent switching power supply, will often start printer, so it is easy to cause internal mechanical and electronic components loss. So will ink-jet printer power and the power of the computer connected to separate different outlet, need to use inkjet printer when it will open, more accord with environmental protection requirement and energy saving ideas.
2, operation don't play too close from spray
Because of ink-jet printer ink, may have to human body potential body damage, even though you may not have direct contact with the ink jet printer's ink, but in the print process will play ink injection may have volatile phenomenon, if ink-jet printer placed far from too close to the user, or the operator in the use of ink-jet printer when the acer aspire 1360 laptop fan printer too close, it is very easy to suction ink volatile gas, used for a long time rate, the human body to produce damage is not ignored. Therefore, the author recommend that users put printer position, you should consider safety, we'll consider the convenience of operation.
3, and spray play connected signal wire cannot too long
As you all know, ink-jet printer is through the signal cable connected to the computer parallel port or USB port, if ink-jet printer and computer too far away from words, so the printer signal cable have be distorted or serious tensile risk, is like this very easy to make ink-jet printer fittings of internal wiring disconnected, and the ink jet printer itself is a weak signal transmission, once outside slightly interference will not work normally, this is why often have friends reflect printer in-and-out reason, in fact, this is because print cable poor contact and cause small fault. In addition we must pay attention to acer aspire 3620 series laptop fan, and spray play connected cable also do not want too long, and will cable best insert to the band switch power board, and the print cable inserted into the power supply in the interface, then open the switch on the power board, if everyone directly in the charged will print cable plug in words, current moment impact may damage the printer circuit.
4, to spray dozen work space to big
Now as household consumption level unceasing enhancement, many users are home to buy computer peripherals more up, but with the increase of computer peripherals, the computer will be many of those peripheral surrounded more and more close, and between peripherals in space take up on will inevitably be conflict, the occupied space between peripherals will gradually reduce. And ink-jet printer as a result of "shape" particularity, inkjet printers usually have two into the paper mouth, one is automatic, is a manual, located in the upper part of the body and the rear. The paper mouth has two direction, above and the front, regardless of which kind of design, need to take up larger space, or in the process of paper is acer aspire 4750 series laptop fan prevented, it is easy to appear paperboard even damage phenomenon of the machine. Ink jet printer using extrusion ink way to print the picture, if printer by collision, can lead to ink head shift, when printing error increased chance of many. By this token, want to own work more conveniently, must give spray play leave a bigger space; At the same time, don't let the scanner, external CD writer, TV boxes and other peripherals near the ink-jet printer, because these equipment in the work to the printer when there is interference.
