The laptop won t turn on and can t be turned off, what should I do?

Press and hold the power on button until it turns off.

The solution to the computer blue screen is software first and then hardware, and there are generally more software problems.

1. The last correct configuration: Before booting and booting the operating system, we keep pressing the F8 key, select "Last correct configuration" and then press Enter.

2. Safe mode: If the "last correct configuration" does not solve the problem, press F8 when you boot up, enter the safe mode, use software such as 360 to repair the system files, and check for viruses.

3. If it can't be repaired, we can enter the safe mode for system restoration.

4. None of the above methods work, and it is recommended to do the following:

Desktop host: 1) Power off, open the chassis, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

2) Plug and unplug the graphics card, wipe the gold finger part with an eraser, and re-insert it tightly (the buckle should be buckled).

3) Unplug the power cord, cut off the button cell battery of the motherboard, wait for three minutes, and then reinstall the motherboard.

Laptop:

Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go.

If the fault persists, the system can only be reinstalled.

The hard disk can be removed and placed in the mobile hard disk box to read the data, you unplug the power battery, wait for ten minutes and then plug in the power supply separately to try it, if any indicator light is not on, this is the motherboard is not powered on, such as a short circuit break point or a problem with the power chip. If it can be turned on, go to the next temperature measurement software to see the temperature. It should be noted that the computer system has a self-protection function, that is, when the computer is used for a long time and the CPU is overloaded and heated, the computer will automatically enter sleep to protect the computer.

We can feel the temperature of the computer's fan heater with our hands, and if it feels very hot, then don't move the computer first, let it dissipate heat for a while and then restart it.

The most likely situation is that there is a problem with your computer hardware, for example, the most likely is that the power supply is damaged, you can disassemble the host to see, when you press the boot button, the power is not started (such as the power supply fan is rotating) to judge. Other possible reasons: It may be that the temperature of the computer is too high, causing the computer to turn on the protection function, so that the computer can fully dissipate heat before turning on and using, and if the performance of the computer is not enough, it is best not to force large games to run, which may burn the CPU and motherboard.

Then there is the possibility that there may be a virus in the computer, which can be solved by antivirus software, or you can reinstall the system.

It is recommended to take the computer to the computer for repair, and do not go to a professional master to repair it for you.

I hope mine can help you and wish you a happy and prosperous new year.
