Laptop motherboard suddenly fails? 5

The system will be damaged if the computer is stuck, the power is turned off, the computer is used for a long time, and the computer is operated at full load. Try to turn on and off repeatedly, put it for a period of time to try, it still doesn't work, it is recommended to restore the system or reinstall. As long as you avoid the problems mentioned at the beginning, you won't have such problems with your computer.

1. There is no display when the computer is turned on, and the first thing we need to check is the BIOS. The BIOS of the motherboard stores important hardware data, and the BIOS is also a relatively fragile part of the motherboard, which is very vulnerable to damage, and once damaged, the system will not be able to operate.

2. The CMOS setting can not be saved, this kind of fault is generally caused by the insufficient voltage of the motherboard battery, which can be replaced, but some motherboard batteries can not solve the problem after replacement, at this time there are two possibilities: the motherboard circuit problem, which should be repaired by professionals; The CMOS patch cord on the motherboard is sometimes due to the wrong CMOS patch cord on the motherboard being set to the clear option, or set to an external battery, so that the CMOS data cannot be saved.

3. After installing the motherboard driver under Windows, there is a crash or the optical drive reading speed slows down, sometimes this phenomenon occurs on some miscellaneous motherboards, after the motherboard driver is installed, restarting the computer can not enter the Windows 98 desktop in normal mode, and the driver can not be uninstalled under Windows 98. If this happens, it is recommended to find the latest driver and reinstall it, the problem can generally be solved, if it really doesn't work, you can only reinstall the system.

4. The mouse is not available when installing Windows or starting Windows. If the CPU of the notebook is broken, the following situations may occur:

It can't be turned on, that is to say, even the power supply can't be started, the power is started, the CPU fan is also turned, but it doesn't heat up, and the display screen is black.

1. It may be that the voltage is unstable and some accessories or capacitors are burned out.

2. The computer is placed for too long or suddenly returns to Nantian, resulting in high humidity in the house, and there is water vapor on the motherboard and the motherboard is suddenly turned on, resulting in a short circuit in the motherboard capacitor.

3. The motherboard manufacturers have long been discontinued, and the old boards that are still circulating on the market are refurbished or problematic motherboards that flow out of the market after repair.

4. Component reasons: The chips and other components on the motherboard are of poor quality, resulting in aging and damage to the motherboard, resulting in the failure of the motherboard.

5. Human reasons: When using the computer, hot-swap hardware at will or touch various connectors with metal objects indiscriminately, resulting in motherboard failure.

6. Dust and static electricity causes: due to dust or static electricity, the motherboard has poor contact, short circuit or burned the chip on the motherboard, resulting in motherboard failure.

1. It may be that the voltage is unstable and burns out some accessories or capacitors.

2.It is also possible that the installation is not suitable, the motherboard is deformed by long-term stress, and the circuit contact is poor or interrupted.

3. The equipment is aging, interrupted or the pre-macro contact is poor.

Boot prompt: Press the trace mode F1 to process experience, and the interface prompts to press F1 or F2.

1. When this interface appears, you can start the computer by pressing F1 directly. After entering the attitude relaxation system, see if the system time is correct, if the date time is not the current time (it will generally become the time when the motherboard leaves the factory). At this time, turn off the computer, unplug the power cord, and replace the motherboard battery.

Turn on the machine and press F1 to enter the system and modify the time. This is due to low motherboard battery. If you replace the battery and change the time, you will still see this prompt (time back to the factory state) after restarting (after a while).

It is most likely that the motherboard is damaged, the motherboard battery is not powering the BIOS chip, or the BIOS chip is damaged.

When the time is no problem after entering the system, restart the computer and enter the BIOS (desktops generally press the delete key, notebooks generally press F2, F12) to set up the interface to see:

Here we take AwardBIOS as an example (different versions vary). After entering the BIOS, select the first item "Standard CMOS Features" and press Enter (as shown in the picture above).

In the new interface, find the following two items, drive A and drive b, all set to "none", that is, there is no floppy drive.

2. The solution is as follows: (1) Press F8 all the time when you boot up, select the last correct configuration, and see if you can enter the system. (2) If not, unplug the memory module, plug it back in, or clean the computer and restart it.

3) Use a USB flash drive to make a boot tool, use diskgenius to detect whether there are bad sectors on the hard disk, fix the bad sectors, and restart the computer. (4) Reinstall the system with a system CD. Here's how:

Preparation: A CD-ROM of the Shooting System. 1. Insert the disc first, press delete (F12, F2, F9, slightly different according to different computers) to enter the BOIS settings after booting, set the first boot device to cd *** (or the item with CD ***) in the boot item, and press F10 to save.

2. Enter the system installation interface, and select one key to install the system to the C drive. Note: If the system is not reinstalled by partition, all the data on the C disk will be emptied, and the data on other disks will be there; The partition reloads the system, and all disks are emptied.

Hello, there is a problem with the power supply, and the white screen prompts that the time setting is incorrect, and the power supply IC should be faulty.

It may be that the battery is insufficient and needs to be charged in time, after plugging and unplugging the power supply, click the Continue option below to enter the start interface.
