Hello, it is recommended that you still take the machine, go directly to the official maintenance department, and ask the master there to help you solve it.

If you can enter the safe mode, it is recommended to uninstall the newly installed software or update, check and kill viruses, update the driver, and close the boot startup test that you do not use.

If you are unable to enter safe mode, it is recommended to enter the BIOS to restore the BIOS default settings test.

If the above solutions do not work, it is recommended to back up the data and restore the system again.

It is recommended that you check whether there is a problem with the power supply first, if the power supply is fine, if the motherboard is just a general failure, the power indicator should still be on.

Specifically, you can first confirm whether your external power supply is in good condition, for example, use a multimeter to measure whether the power supply is stable, and then check whether the power interface on your computer is in good condition, and then check whether it is a motherboard failure.

3. When the machine is turned on, it prompts that the serial port, parallel port, hard disk, etc. cannot be recognized;

Fourth, the computer cannot enter the system after the alarm is turned on;

5. Operating system problems.

If the laptop won't turn on, it's best to find a professional repairer to check it.

To see if the computer is plugged in, the second is to unplug some memory modules and hard disks, and the third is to reinstall the system. If the system can't get in, the hardware of the computer itself is broken.

1. Check whether all the plugs of the power supply and the wires on the adapter of the notebook are firmly inserted into their respective sockets, if not, it means that the contact with the power supply is poor, just press the plug down again.

2. If the indicator light is not yet on, on the premise of ruling out the power adapter, it must be that there is a problem with the power chip of the motherboard or a short-circuit breakpoint, and the motherboard is not powered on.

3. If the indicator light responds but the screen is black, it may be a problem with the graphics card or memory.
