You have installed a new CPU, and the interface may not be properly connected.

The first sentence prompts you.

Questions. How to pick it up.

I opened it and asked him to change the PIN code.

Then you can't open it.

Isn't it the CPU you replaced?

Have you fixed this computer before? Recent.

Questions. Not really.

I ran out yesterday and turned it off.

That's it as soon as I open it today.

The first thing you write is that the CPU interface is bad.

Did someone else bump into it? Or what's going on?

The first sentence of the opening sentence in English is that the CPU does not exist.

What causes it? You're going to see what was going on before your last shutdown? Is there a system patch being updated?

Or is it the result of what software you installed? In either case, you can rebuild the system, but if not, your computer hardware may have a problem and need to be repaired.

Hello dear, the above are several reasons why the computer can't be turned on, you can take a look, and feel free to consult me if you have any questions [smile].

If the computer doesn't turn on, it may be that too much dust has accumulated on the internal memory module, causing the computer program to not run.

2.If there is an abnormality in the power supply of the motherboard, it may also cause the computer to not turn on, 3If the computer system is damaged, it will not be able to boot.

1. It should be caused by changing the partition ** and not being able to start with UEF....This should be the system file corruption, or lost, the machine can boot, not the hardware problem, the repair method is as follows: 1. In something else.

1. The motherboard is not powered on. Solution: Try to release static electricity (remove the battery and power cord of the computer, make sure the notebook is in a completely unpowered state, press the power switch 6-8 times repeatedly, continue to press and hold for 6-8 seconds each time, connect the power supply and try to turn it on), if it can be turned on normally, the fault will be solved; If it still can't be turned on normally, it is recommended to send it to the local service station for testing hardware;

What is the reason why the computer won't turn on? First of all, we have to analyze the situation that the computer cannot be turned on.

If the laptop cannot be turned on after continuous charging, please debug it according to the following scheme: 1. Release static electricity 1. If the laptop only has an "external" battery, the operation method is: after the main computer is powered off, unplug all the fuselage.

I don't know your specific symptoms, but I feel that there is no response after pressing the power button, just like the computer is not powered on, it can be analyzed from the following aspects: 1 There is a problem with the switch itself, 2 There is a problem with the power supply.

If the notebook only has an "external" battery, the operation method is: after the main computer is powered off, unplug all cables and connected devices on the body, remove the external battery, press and hold the power button for 10 seconds, press and hold it 3 times, replace the battery after the operation is completed, connect the power adapter and turn on the power again.

The reason why Lenovo notebooks can't turn on is that the motherboard is not powered on. Solution: Try to release static electricity (remove the battery and power cord of the computer, make sure the notebook is in a completely unpowered state, press the power switch 6-8 times repeatedly, continue to press and hold for 6-8 seconds each time, connect the power supply and try to turn it on), if it can be turned on normally, the fault will be solved; If it still can't be turned on normally, it is recommended to send it to the local service station for testing hardware;

Here's how to solve it:

1: If the power cannot be turned on, you can try to unplug all the external devices of the host, press the power button 5 times at an interval of 2 seconds, and then connect all the external devices to power on for testing. This is the way to dissipate static electricity, which can cause the problem described if static electricity is generated in the computer.

Two: If it can be opened, but it can't be done on windows:

During the boot process, select Last correct configuration boot. If it cannot be resolved, proceed to the next step; During the boot process, pay attention to press the "F8" key to enter the safe mode, in this mode by importing the backed up registry, antivirus, view the hardware device manager to uninstall and reinstall the belt! "Driver of the device; A faulty keyboard or not plugged in properly can also cause a blue screen with the "keyboarderrorornokeaboardpresent.""If there is no problem with the keyboard and motherboard plug interface, clean the keyboard connector and plug it in again. Boot up normally and no display, check whether the power cord, switch, and data cable of the display are correct, or it may be that the display is damaged, which can be easily troubled by observing the situation of the host, starting sound, etc.; Reinstall the system.

1. Check the power supply or battery (check whether the battery is charged when the laptop is not connected to the power supply).

2. First of all, check whether the hardware has any problems with poor contact, and wipe the contact part of the gold finger (memory module) with an eraser.

3. Remove all other hardware and only plug in the memory to the machine, listen to whether there is an alarm sound, if there is an alarm sound, if there is no sound, it should be a problem with the memory or motherboard. Try again with the replacement method. It is only after many troubleshooting that you can know what the problem is.

Other related: Generally, the memory cannot be turned on because the power of the power supply is not enough, but the new memory is still not turned on, which may damage the memory slot, or burn a certain part of the motherboard.

Unplug the memory and turn it on. Being able to hear an alarm sound means that the motherboard and CPU are fine, and not hearing the alarm sound means that the motherboard and CPU are not working properly. Try it with a good power supply. If you still can't hear it. Then it's most likely a motherboard issue.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

It may be a problem with the system, I helped someone else's laptop get it, and it's OK after using a one-click restore.

It could also be a hardware issue, such as memory. Problems with the computer are usually solved by troubleshooting.

If you don't hear a tick when you turn it on, it means that the memory module is not plugged in properly.

I can't turn it on when I turn it on, it's not a system problem, it's a stupid wipe downstairs. Go and repair it, it can't be turned on, and the problem is unspeakable.

Lenovo has that one-click restore.
