Is there any way to fix the situation that Lenovo notebook won t boot

Solution 1 for Lenovo laptop won't turn on:

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 3: If no virus is detected, you can use the "System Restore" function of the operating system to restore the system, and if the system is normal after the restore, the failure is caused by system corruption. If the fault persists, it may be caused by the incompatibility of the device driver with the system; Then delete the drivers of the sound card, graphics card, network card and other devices, and then install the drivers one by one, restart the computer every time you install a device, to check which device's driver caused the failure, find out, ** the new version of the driver of the faulty device, and then install it.

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.

Step 9: If you are able to boot Safe Mode, it is caused by the incompatibility of the device driver with the system. Then delete the sound card, graphics card, network card and other devices, and then install the drivers one by one, install one by one, and start once to check which device's driver is causing it'Fault.

There is a problem with the system booting.,You need to use third-party software to fix it.,Prepare a USB flash drive PE bar。

Step 1: Insert the PE of the USB flash drive, turn on the computer, enter the interface of the USB flash drive system normally, and select the PE in the interface and press enter to enter. Step 2:

Open the DG software in the PE system, select the system disk in the DG software, and click Rebuild Master Boot Record (MBR) under the disk in the menu bar.

Step 3: Some warnings will be prompted when rebuilding, at which point select Yes directly. Step 4: After completion, click Save in the upper left corner of the software, after saving, the computer will restart to take effect and successfully enter the system, and there will be no more grub > and cannot enter the system.

In life, computers have become an indispensable tool for people's office and entertainment, and computers often fail to turn on

Tools Raw materials.

Another computer, Wedge.

Method steps.

1 5 step by step reading.

First of all, observe whether the computer is connected to the power supply, whether the monitor switch is on, if the connection is normal, 2 5

Observe whether the keyboard display light of the input device is on, if it is on, please check the power cord of the display, if the keyboard display light is not on, it means that the computer does not start normally, but the brain hardware device is faulty.

The wedge opens the main chassis to detect the three major components of the computer, the CPU motherboard and the memory module, if there are other normal computer equipment, you can plug and unplug the memory module to observe the normal boot.

Secondly, observe whether the motherboard has visible damage and odor, and whether the booted computer is normal self-check.

Finally, observe whether the white transparent slime "silicone" in the CPU and fan exists, if it is not possible that the computer will burn the CPU after long-term operation of the silicone, if there is still silicone, please recall that when you use the computer, whether it is a large-scale application program or the machine itself is upgraded from win7 to win10, it will burn the computer CPU.

Precautions. Please turn off the power to avoid electric shock when repairing computer hardware equipment.

1. If the screen is black when running a specific program, please try to uninstall the program and reinstall it, or install it in a different version.

2. Enter the safe mode, and confirm whether there is a black screen in the safe mode? If the bug is normal in safe mode, it is usually caused by software conflicts, please check whether there are any system optimizations and software installation operations in the near future, and you can uninstall the recently installed updates and program software through [Control Panel] - [Programs and Functions].

4. Check whether the computer has been installed with memory or other hardware? If so, please remove the additional memory and other hardware before turning on the computer to confirm.

5. If it is still invalid, it is recommended to back up the data and judge it as soon as possible, and try to restore or reinstall the system.

For the problem that the laptop does not boot normally, you can deal with it in the way of software first and then hardware. ......Specifically, the problem is solved by first troubleshooting the software, then trying to reinstall the system, and finally troubleshooting the hardware.

1. Troubleshoot the software first, and try to fix it.

The computer's failure to start the liquid properly may be caused by a software malfunction. ......This type of failure is divided into two types: system software failure and application software failure. ......We can find the fault point through troubleshooting and try to solve it through software repair.

If the system returns to normal after repair, you can use the computer normally.

2. If the software failure cannot be repaired, you can try to reinstall the system.

Sometimes, the failure of the system software cannot be repaired, and the intelligence is solved by reinstallation. ......There are two ways to reinstall the system: installation method and image recovery method, and the operation methods of these two methods are different from Xiangling, but the final result is the same, and the goal of reinstalling the system software can be achieved. ......When the system is reinstalled, the computer can be troubled and can be used normally.

3. If the troubleshooting software cannot eliminate the fault, check the hardware fault.

Sometimes, the computer does not start properly because it is not due to the software, but because of the hardware failure. At this time, it is necessary to solve the ...... by troubleshooting hardware failuresYou can use the minimal system method to troubleshoot each piece of hardware one by one, so that you can find the fault point faster and improve the speed of fault handling. ......Damaged hardware can be repaired or replaced.

When the fault is eliminated, the computer can be started and running normally.

Generally, this situation is a system crash, choose to reset the system.
