Handling suggestions: according to the principle of easy to difficult, software first and then hardware, it is recommended to reinstall the system, which is the easiest and fastest way, if the reinstallation of the system is successful, it can also eliminate the possibility of hardware problems.

One. Restart the computer: Restart the computer by pressing the host restart button or press and hold the power button to shut down and then restart the computer, if you can enter the system operation normally, it means that the last abnormal operation is only an occasional program or system running error, and it does not matter.

Hello, I am happy to answer your questions, has found the answer for you, first, check the computer power supply first to confirm whether the power supply of the laptop is normal, if there is no power connection, or the power plug is not plugged in tightly, it may cause the computer to not turn on. Therefore, you should first check that the power supply is properly connected and make sure that the power plug is plugged in tightly. 2. Check the battery If the computer is not connected to the power supply, it may be caused by the fact that it has no battery, the battery is depleted, or the battery capacity is insufficient.

In this case, the cracker should be inspected to see if the battery is charged, and if not, a new battery should be inserted into the computer. 3. Update BIOS If the computer power and battery are checked and still cannot be turned on, there may be a problem with the BIOS. In this case, you can try to update the BIOS so that the issue can be resolved.

4. Check the hardwareIf the computer still can't be turned on after the above steps are completed, then it may be caused by hardware problems. In this case, you should check whether the hardware is damaged, such as CPU, memory, hard disk, etc., and if so, you should replace it with a new one to ensure the normal operation of the computer.

If this is the case, it is usually caused by the computer booting up and not finding the system, which may be caused by a failure in the boot item, or a broken system and a fault in the hard disk itself.

First of all, confirm the first possibility, if the computer has an external device, such as a USB flash drive, etc., unplug it first and then restart the computer to see if it can enter the system. If you can, go to the BIOS, change the hard disk to the first boot item under the "Boot" option, and then press F10 (or FN+F10) and select Yes to save.

If the modification is invalid, it is recommended to reinstall the system to solve the problem; However, if the hard disk cannot be found in the BIOS, try to restore the default settings in the BIOS, and select Yes for F9 (or FN+F9); Press F10 (or Fn+F10) and select Yes, if it still doesn't, consider a hardware failure.

From your ** point of view, the power supply is normal, is there a BIOS ** when booting, this is the key to judging whether the motherboard has started, if the BIOS has not started, then it is a problem with the motherboard, if there is, then it is a problem with the hard disk, you can use PE to check that the hard disk has bad sectors, if it is good, try it from the new installation side of the system, it can generally be repaired.

Reasons and solutions for the computer not to turn on: the first step: first analyze according to the specific situation, if there is no power response directly, then check whether there is a power supply, poor contact, hardware and other problems, go to the second step, if it is not possible to enter the system may be an operating system or software problem to the third step.

Step 2: Check whether there is a power supply problem, first see if the power supply is not plugged in well or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or go to a computer repair shop or sales store to find the same model of power supply to try it.

After replugging the power supply, press the power button again, and if it still can't be turned on, then press it for a while. If you change someone else's power supply to turn on, it means that there is a problem with the power supply, if it proves that there is no problem with the power supply, it may be the hardware reason, go to the fifth step. Step 3:

Go to the last correct configuration to adjust, turn on and press and hold F8, enter the advanced options page, select "The most recent correct configuration", and then press Enter. If it can enter the system, it may be caused by viruses, incompatible hardware drivers with the system, or operating systems. After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, restart it after removing the driver, if there is still a problem, then go to the next step.

Step 4: Repair and install or reinstall the system, set "Optical Drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to perform "Repair and Installation". If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

Step 5: Check whether there is a hardware problem, disassemble the notebook to see if the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to sound that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it can't be started at this time, it is best to send it for repair, and the professional will check whether there is a problem with the hardware one by one.
