It may be that the system you installed is not compatible with your laptop, and this situation occurred in the past when I helped others install the system, and there is also a problem with the boot startup item, and you check the ......

Dear Lenovo users, hello!

Reset operation first, reset: Please unplug the power supply, battery and other external devices from the computer (make sure the power is completely off); Then press and hold the power button for about 20 seconds; After that, connect the power supply and battery to the machine, and then turn it on. After entering the system, try to repair it, win7 click Start--Program--Attachments, right-click on the command prompt, select Run as administrator, enter sfc scannow in the pop-up command prompt window to automatically detect and repair system files.

Win8 Press Win+X once, select Run Command Prompt as Administrator, and type: SFC ScanNow automatically detects and repairs system files.

The first 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 and black screen.

Solution: Send it to the after-sales service or repair shop to repair the motherboard.

The second reason: the screen cable of the notebook is broken or poorly contacted, resulting in no image signal transmitted to the screen for display, that is, a black screen.

Solution: Ask the person repairing the notebook to plug the screen cable back in, or replace the screen cable.

The third reason is that the power adapter of the laptop is damaged and cannot be powered on, or the battery of the laptop 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.

The fourth reason: The memory and graphics card of the notebook are oxidized, resulting in poor contact with the memory slot or graphics card slot, resulting in a black screen that cannot be turned on.

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.

The fifth reason: The video 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, and because the graphics card is broken, it will naturally not be able to boot up, and the screen will be black.

Solution: Repair the graphics card or replace the graphics card.

Hello dear! <>I'm your exclusive answerer, Xixi<> I've already sorted out your questions<>

I'm very happy I'm here for your question, dear, according to your question The following are <> the laptop has a black screen but the processing method is as follows: 1. It may be in a dormant state now, the notebook hibernation is that the notebook is in a resting state, and then the notebook is in a state of suspended death and black screen, which will be mistaken for a black screen, as long as you press any key of the notebook to restart, the notebook has not been used for a period of time or enters a state that displays low battery power, and the system can start sleep and hibernation mode, If you use the computer for a long time and forget to turn off the black screen of the computer, try to connect it to the power supply and charge it for a while to use the laptop. 2. The screen is black after booting, but you can make sure that you can enter the system normally when you hear the sound, try to connect an external monitor to see if the output of the graphics card is normal.

If an external monitor can boot and display normally, it is a problem with the laptop LCD screen or wiring. 3. It may be caused by bad exposure. It is recommended to restart the laptop.

If the problem still can't be solved, it's a broken display. It is recommended to go to a repair shop for repairs.
