How to solve the black screen when the laptop is turned on

Since the notebook is a whole machine, the general environmental conditions are not too bad, and it will not cause a number of faults caused by overheating, including the black screen, in my maintenance experience, under normal circumstances, the black screen of the notebook is rarely caused by a virus or something, because now people have a good sense of protection, and the common black screen is caused by improper use by the user, because the current notebook system rarely has win10 outside, most of them are win10 If yours can also start with the system, Because win10 background system update, if the update is not completed to cause interruption, is a common fault of the notebook black screen, if you can still boot to the operating system, it is recommended to click start, and then click on the settings (pinion) to find 'update and security' to open the update, if there is a red exclamation mark to start immediately, then click, and then wait patiently, until the new welcome interface appears, you can effectively avoid the black screen. If the screen is already black and the phone does not turn on, then you can restart it several times repeatedly until the system repair interface appears, click System Repair. That's it.

Hello friends:

First of all, try the following operations: remove the battery and power adapter, press and hold the switch button for 30 seconds to discharge the static electricity, wait for about 15 minutes, and then connect the power adapter separately to power on; If it can't be turned on yet, it is the following reasons.

1) The first reason is that the power adapter of the notebook is damaged and cannot be powered on, or the battery of the notebook is out of power, and it cannot be turned on from the surface to the black screen. Solution: Replace the power adapter or fully charge the battery.

2) The second reason: is that the memory and graphics card of the notebook are oxidized, resulting in poor contact with the memory slot or graphics card slot, resulting in inability to turn on, black screen, treatment method:

Solution: It is to remove the power supply, open the back cover of the notebook, take out the card slot of the memory, if it is not an independent graphics card soldered to the motherboard, also take out the card slot, align the part of the memory and the gold finger of the graphics card (that is, where there is a copper sheet) and wipe it back and forth with an eraser a few times, blow the ash, and then insert it back, cover the back cover, and it is generally OK to boot up.

3) The third reason: is that the graphics memory of the notebook graphics card is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, because the graphics card is broken, it will naturally not be able to boot, and the screen will be black.

4) The fourth reason: the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to boot, black screen, IO problems, unable to start the computer, black screen, etc., Solution: Send after-sales or repair shop to repair the motherboard, I hope it will help you, I wish you happiness
