What s going on with Lenovo computers not turning on properly???

Hello! It is recommended that you install 360 Security Guard, repair the system and try it, if it doesn't work, reinstall the system!

It's a little unclear what you're talking about, can't tell what's going on! Is it the desktop that has improved when it is turned on normally, or is it not responding when you press the power button?

Hello friends:

There are many reasons why a computer can't turn on properly, and there are four main aspects:

The first aspect is that the memory is oxidized, resulting in the inability to turn on, it is recommended to take out the memory module, erase it with an eraser, and then insert it back, which can generally be solved.

The second aspect is the system failure, so the system needs to be reinstalled.

The third aspect: if the system starts faulty, resulting in failure to start, it is necessary to use a USB flash drive with PE to enter the PE for system startup repair.

The fourth aspect: that is, the master boot record is wrong, resulting in the inability to enter the system, the master boot record must be rebuilt.

Hope it helps you and I wish you happiness

This is the case that the Lenovo computer does not turn on normally. You redo the system. There will be no problem.

1. The motherboard is not powered on.

In fact, it is a common phenomenon that the computer can't turn on, if you want to solve such a problem, you must first understand what causes the Lenovo notebook to not turn on, under normal circumstances, there are many reasons why the computer can't turn on, such as system damage, battery failure and other problems. In this case, you should remove the battery and power cord of the computer, make sure that 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.

Second, the system was compromised.

After the computer is turned on, the power display of the indicator light is on, and the display screen is also on, but there is no way to enter the system, in fact, this problem is caused by system failure, you can try to press the F8 key when you turn it on, enter the safe mode, and then enter a security configuration to enter the trial, if it still does not work to stare at the reed, it is recommended to reinstall the system.

Third, the problem of CPU.

If there is no problem with the electric Kai with band source** and the display itself is good, but it is still silent, it may be that there is a problem with the CPU, which includes the CPU is not plugged in properly, the overclocking is too fierce, and the frequency is adjusted too high, so that the CPU can't run at all, and the CPU core voltage adjustment is out of range. If the above problems are dealt with, it still can't be started, it may be that the CPU itself is broken, try a different CPU.

1. The motherboard is not powered on. Solution: Release static electricity try (remove the battery and power cord of the computer, make sure the notebook is in a completely unpowered state, repeatedly press the power source switch of the electric hole socks 6-8 times, continue to press and hold for 6-8 seconds each time, connect the power supply and try to turn 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;

2. The display screen is trembling or the graphics card is faulty. Solution: It is recommended to send the local service station for testing hardware;

3. The system is damaged. Solution: If you are using a pre-installed genuine Win7 system, it is recommended to restore the backup data in the logo interface by pressing Alt+F10 with one click; If you are not using a pre-installed system, it is recommended to back up the data and reinstall the pants leather system;

The following describes how to diagnose the failure to boot the operating system.

First, check to see if the computer has started booting up the operating system when you turn it on. If the operating system freezes, blue-screens, or automatically restarts when the operating system is booted, the partition table and master boot record of the hard disk are normal, and the fault causes such as the corruption of the hard disk partition table, the corruption of the master boot record of the hard disk, and the loss of the hard disk partition end flag are ruled out. The following method is then used to make a diagnosis.

Step 1: Start the computer in safe mode to see if it can boot, if it can't boot, it may be infected with a virus, system files are missing, the operating system is damaged, the hard disk has bad sectors, the hardware device has a conflict or the hardware has a problem, go to step 4; If you are able to start Safe Mode, it may be caused by the hardware driver being incompatible with the system, the operating system is faulty, or it is infected with a virus.

Step 2: Then run the antivirus software, if there is a virus, it may be caused by a virus, restart the computer after the antivirus, if it is not normal, you need to reinstall the operating system.

Step 4: If you can't boot from safe mode, then reinstall the operating system with the installation disc. If you can install the operating system normally, go to 7 steps; If there is a failure when installing the operating system, such as a freeze, blue screen, reboot, etc., which causes the system to be unable to be installed, it should be caused by a hardware problem or a poor hardware contact.

Step 5: Then clean the dust in the computer, clean the gold finger of the memory, graphics card and other equipment, reinstall the memory and other devices, and then reinstall the operating system.

Step 6: If you still can't install the system, it could be a malfunction caused by a hardware issue. Then use the replacement method to check the hardware failure, and replace the hardware after finding it.

Step 7: If the operating system can be installed normally and the fault disappears after installation, it is a fault caused by corrupted system files.

Step 8: If the fault persists after installing the operating system, it may be caused by bad sectors on the hard disk or the device driver is incompatible with the system. If you boot your computer in safe mode, if it doesn't boot, it's a malfunction caused by bad sectors on the hard drive.

Then use NDD Disk Utility to repair the bad sectors.
