When the computer run unstable,dell inspiron 1405 laptop cpu cooling fan appear after the power supply can't start when the phenomenon such as if you exclude the power, memory and software virus by factors such as the possibility of failure after the next need to check whether the CPU. By the CPU performance is caused by fault although varied, but to sum up outside also frequently crash, the working frequency of shows on self-inspection repeatedly for change, overclocking excessive and can't boot, and system, electric without any reaction after several ways. Of course, deal with measures also are different, next we will be introduced respectively:
1. Frequent crash
The fault phenomena are common, the main reason is generally work by cooling system, the undesirable socket contact undesirable, CPU and the relevant CPU high temperature alarm set caused by error, etc. The strategy is primarily CPU dell inspiron 1420 series laptop cpu cooling fan heat dissipation, around plug-connecting is reliable and check the BIOS setting. For example: check the fan is normal operation (when necessary can even change a big row air fan), check the heat sink to the CPU is good, thermal contact silicon grease coating whether uniform, take down CPU check pins and socket contact is reliable, and enter into the BIOS setting temperature adjustment protection points, etc.
2. The working frequency of self-inspection show on not normal
Specific performance for boot CPU dell inspiron 14r series laptop cpu cooling fan work after reduce the frequency, the display "Defaults CMOS Setup Loaded" clew, in the CPU CMOS reset after parameters, the system can resume normal display, but failure will appear again. Produce this kind of situation and CMOS battery or main board of the corresponding circuit. Meet the problem can follow after the first easy to maintenance principle, the first measurement of the motherboard battery voltage, if the voltage value less than 3 volts, should consider replacement CMOS battery. If the replacement battery before long, fault and appear, is the main board of the existing power supply circuit CMOS components leakage, this time should be repaired motherboard.
3. Caused by excessive overclocking unbootable
Excessive after overclocking, computer dell inspiron 1501 series laptop cpu cooling fan start may arise when a cooling fan rotation normal, and hard disk lamp light only for a while and didn't reaction, the display also maintain standby mode of failure. Because now can't go into the BIOS setting options, therefore, it can't give CPU frequency reduction. In that case processing method is of two kinds:
(1) open box on the mainboard and find the discharge jump line to CMOS (usually arranged in button cells near the), it will be set in "CMOS discharge" position or dig out the battery, waiting a few minutes after a little time, and then will jump line or battery reset and restart your computer can.
(2) is now a new motherboard, most of the restorative measures for overclocking failure. For example: can be turned on hold Insert in key not to put, this time after it starts will be automatically into the BIOS setting options, then frequency reduction operation can be carried out. And in some more advanced motherboard, still can be in after a failed overclocking initiative "to restore" the default CPU dell inspiron 1521 series laptop cpu cooling fan running frequency. So, for overclocking keen and the lack of practical experience and the common reader who choose to contain "sign by overclocking," "overclocking resume automatic failure" of human function main board, can make the work to be an overclocking CPU simple easily.
4. System, electric didn't respond
General in the meet this kind of failure can use "substitution" to determine the fault of the specific area. If eliminate the motherboard, power trigger the possibility of failure, it can determine the problem and more CPU dell inspiron 1526 series laptop cpu cooling fan is for the circuit inside the damage. If so, can only by changing the CPU to solve
.
Tip: some people think that the speed of the CPU cooling fans, the higher the cooling effect of the more good, actually this kind of understanding is one-sided comparison. In fact fan cooling capacity and fan leaves much, Angle, and effective exhaust area, exhaust air had direct contact, and improve speed may be improving exhaust air, but will bring noise increases, shorten service life. Therefore, in choosing the cooling fans dell inspiron 1720 laptop cpu cooling fan should be considered.
