1. The first hard disk boot
There are many people ignore the computer dell precision M4500 laptop keyboard equipment of the boot sequence, many people will start from the cd-rom, so that in the boot will read cd-rom, if drive have CD will delay your boot. Even if no CD, also can let the system was started reading the cd-rom, for the life of the drive is not good. Therefore, it is necessary to its close.
Press Del button to enter BIOS Setup, select the BIOS Features Setup menu, and then press enter key, enter the parameter Settings interface, in this interface to find and select options Boot Sequence, and then press Page Down key or Page Up key, select the CDROM, C, A setting system priority from C disk Boot, final connection press the Esc key returned to root menu and select save menu or direct press F10 key dell precision m60 laptop keyboard saving can.
If you use a Phoneix BIOS in the Boot press F2 key, enter BIOS Settings, select Boot options, and then find the HardDrive items, the continuous press "" number key, make its adjustment to the former can make sure the machine from the hard disk Boot priority.
2. Enable Quick Boot
Most of the computer dell studio 1555 laptop keyboard BIOS has a Quick Boot item, in the "Advanced BIOS Features (BIOS Advanced options)", it will be set to Enable, such BIOS in every Boot wouldn't hardware detection, can greatly improve the system startup velocity.
3. Shielding off unnecessary equipment
Despite the parallel and serial interface is no longer popular, but there are a lot of motherboard is still at the interface. At this time, we can in the BIOS will shield off, so that can also speed up the system startup velocity. Enter BIOS, and then select "PNP, PCI&ONBOARD I/O" item, select its Onboard Serial Port1, press PageUp or PageDown key, set it as the Disable (banned) state can turn off the Serial port, press F10 key dell studio 17 laptop keyboard, save modification, restart your system can. Of course, using this method also can lock IDE2, parallel, USB and floppy disk, etc., this can let Windows not loading their driver, nature would quickly out many.
4. In Windows banned unnecessary hardware
For the machine does not use hardware, don't let Windows reload their driver, can open "control panel", double-click the dell studio 1745 laptop keyboard system icon, and then click the "hardware" labels, click on "device manager" button to open the "device manager", right-click the corresponding equipment, select "properties", again in the open window click on "equipment usage" drop-down list box, select "don't use this equipment (moved)" and click "ok" button twice confirm change.
5. Reinstall the hardware
If your computer installed more hardware, but confirmed that they no longer useful. That one discharge is not advisability lift, because most people don't know the drive in hard disk where scattered, root impossible to clean. Then we can put all don't hardware take down, and then the Windows installation CD inserted into the drive, and open the cd-rom SUPPORT \ TOOLS folder, double-click DEPLOY. CAB file, among them all files unzip to a folder (such as d: \ Sysprep), double click one of the Sysprep. Exe file, and press the "ok" button to accept warning information. And selected window "no replacement activation grace period", "use minimize installation" and "detection not plug and play hardware" check box. Press the "back closed" button and the machine will automatically shut down. Restart the computer, Windows XP will let us accept the agreement, input serial number dell studio 1747 laptop keyboard, and can specify the system administrator and password, and at the same time to test hardware and reinstall the driver. Because the Windows to detect and install the driver, so that the system hardware is "clean", will no longer exist redundant drive, the system will naturally fast out many.
6. Prohibit unnecessary service
Now most people use Windows 2000 / XP system, but there are more than 90 service, the default open it up to 30! In fact, as long as six is enough, banning all the "do not need to" service will save 12-70 MB of memory, let our computer speed faster.
Press Win R, again services. MSC and return can finding system service management window, then can see system of service, every name followed behind description, double-click any service, will pop up a the dell studio 1749 laptop keyboard properties window. If feeling this service without too much effect, will be able to click on the "stop" button, click on the "start" button can be opened this service. Adjust the service of open, restart your system can be effective.

WebOS open source operating system to reduce the number of development
Hewlett-packard announced on Friday to hp g61 110sa laptop keyboard external open source operating system WebOS first open beta version, allow external company and application developers for its development and application. But it is not clear HP his plan for WebOS how much power input. According to professional networking sites LinkedIn personal information display, there have been hundreds of had engaged in WebOS project development staff have been transferred to the new post, or have quit.
In December 2011, HP has said there are 600 employees working in WebOS project development work. To this Friday, hewlett-packard has refused to disclose at present how many employees still WebOS work. But according to the information display LinkedIn,hp g61 400sp laptop keyboard about 300 HP employees in your resume, mentioned WebOS. In the above 300 employees in, about 170 people in your resume, says there are still engaged in WebOS project development, more than 90 other people said they had engaged in WebOS project development, but the present has set up a file in the HP engaged in other projects. Surplus personnel only in resume mentioned WebOS, and no detail currently engaged in what kind of work.
Many who had engaged in WebOS project development personnel at present mainly concentrated in the nine company. About 240 once the WebOS project developers in LinkedIn, said their current on apple, Google, nokia, Sprint, qualcomm, Intel, Microsoft, Lab126 and Barnes and Noble work.
The personal information indicates that LinkedIn,hp g62 225nr laptop keyboard WebOS current in HP's development team has without ever so powerful. But considering WebOS, the history of this is not surprising. HP tablet PC TouchPad had pick up this kind of mobile operating system, expect to iPad apple in the market in counterbalance. But in the last year listed just seven weeks later, because sales are too weak, HP will cancel the TouchPad project.
Hewlett-packard announced in last December, the hp g62 a40ep laptop keyboard company will put WebOS as a open source operating systems continue to keep down. The company released on Friday WebOS first demo version. WebOS global developer relations director Edna McGregor with las (Enda McGrath said, because WebOS part ownership of need to use open source code to replace, causing HP it took her a long time to launch the first open beta version.
Hewlett-packard to WebOS has high expectation, hope the hp g62 a50st laptop keyboard other companies can use WebOS operating system, and it is introduced into the intelligent mobile phones and plate of computer. Open to the outside world WebOS, can let this kind of the operating system into various types of mobile devices, sensors, safety equipment, and even of the robot. HP said, the company will continue to develop WebOS.
WebOS senior vice President Martin renesas Mr (Martin Risau) said, "we are not released after WebOS regardless of whether, waiting for what happens. Our plan is to continue to develop WebOS."

How to make use of the CD writer live longer
A, dust seize any opportunity often cleaning is the key
This problem is closely linked toshiba qosmio x500 series laptop cpu cooling fan with everyone, after all, we live in a dust all-pervasive environment, so keep a CD writer cleaning is also a very important thing. It is not only to CD writer, for all the cd-rom products it are also important. But due to the CD writer has written the function of CD data, and its own clean degree is increasingly important. If the baldheaded there on dust words, then burn the possibility of failure will greatly increase, so we have to remember that must not frequent will CD writer tray long time exposed, lest dirt into the CD writer internal. To attract into cd-rom words on the computer in the environmental requirement will be higher some. If dirt and other particles into the CD writer inside, in burn, dust is easy to adsorption to the high speed rotating disc, if dust and just and CD writer of the branch with platform contact, it is possible in the disc left or long or short lines, thus affecting the CD burning quality, even make disc scrap (that is, frisbee). If the particles and baldheaded happen contact, and may damage to baldheaded, and ultimately damage to CD writer itself, so in daily to CD writer within certain cleaning is very necessary, especially in before burning. For instance can use special cotton swab to cleaning. Don't neglect the job, if maintenance well, CD writer life can be greatly extended.
Second, let dvd-rom/CD writer take responsibility
If the economy's consent, suggest that we will be as far as possible with double drive, namely a CD writer and a DVD player - ROM. So as far as possible to avoid letting the CD writer do some read disk aspect work, also let dvd-rom function is fully play. After all, even if current CD writer is already full capacity, also still can't replace toshiba qosmio f15 series laptop cpu cooling fan dvd-rom in dish friend heart status. And in so doing the biggest advantage is that, can let CD writer focused on burn work, greatly reduces the CD writer utilization rate, its life is inevitable to improve things. For CD writer speaking, the quality of the blanks on its service life length plays a key role, if you usually chosen mostly market those cheap inferior disc, so CD writer in the work will have some sweaty, thus can cause excessive CD writer "fatigue".
Three, inferior disc as far as possible not to buy
Although at present more companies launched such as automatic learning "sa sword" technology, enhanced write policy intelligent discriminant technology and so on, but ultimately are some emergency measures, for CD writer itself and not too big benefits,toshiba qosmio f20 series laptop cpu cooling fan so or suggest that we buy some quality is good blanks. After all, many blanks for storing data or file and so on, disc quality directly affect the save time and information security, small investment still want to see some long term.
Four, prevent CD writer "heat"
Immediately the beginning of July, is also one of the hottest summer time, we want to sunstroke prevention, CD writer also cannot ignore the problem of temperature. Those who used CD writer friend will certainly know, in a copy CD from CD writer toshiba qosmio f10 series laptop cpu cooling fan after the completion of out of the time, the CD is a slight fever, and if continuous burn number's later, CD burner and burn out of the disc feels will some hot, then we should let it rest for a while.
Five, the chassis space in the design is very important
For computer accessories for, high temperature is not a what good things, CPU, hard disk is such, CD writer nature is no exception, so we try not to let CD writer uninterrupted continuous work burn for a long time, in the work process regularly make CD writer "rest" it is absolutely good. Because the author toshiba qosmio f30 laptop cpu cooling fan once in transverse test disc, a particular CD writer for 10 hours kept on test, leading to higher temperature and stop working. Although this kind of situation will not occur in most of his friends, but still worthy of attention.

Save hard disk ten unique skill
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.

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.
