What system is the black screen? If it's win7, it's a problem with win7, if it's an Apple system, then you have to go to the after-sales service, and the Apple system has a black screen, and it basically has to be operated.

The laptop screen is black, it may be a problem with the software or hardware.

One, the black screen caused by the software.

Sometimes after installing some software or hardware drivers, you find that after restarting, the computer can't enter the system and the screen has been black, which is the black screen of the laptop caused by the software. If the black screen is caused by software, take the Windows system as an example, you can restart the machine, press the F8 key several times when booting up, and bring up the system's boot options menu.

Once the System Boot Options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

Second, the hardware causes the laptop to have a black screen.

Hardware-induced black screen for the following reasons:

1) The cause of static electricity, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power start of the laptop several times to let the machine release the static electricity. Then connect the power supply, turn it on, and see if it can solve the fault.

2) The memory is loose or the memory has a hardware failure. There are several major components of a laptop computer, including the CPU, motherboard, memory, and graphics card. These parts are indispensable, as long as one of them has a problem, it will cause the laptop to not function properly, the most common is that the boot does not respond.

In general, the probability of CPU and motherboard failure is relatively small, and it is more common for the laptop to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook, if it is not difficult to remove the computer, you can open the back cover of the notebook by yourself and reinsert the memory. After plugging in the memory, power it on again, start the machine, and see if you can solve the fault.

3) The LCD part of the notebook is faulty. There are some notebooks that are a little older, and this may be the case. Display components generally include displays, data cables, and some other small parts.

If you have a desktop monitor, try plugging it to the VGA display connector on your laptop, and then switch the display to the VGA external display on your laptop. If you can switch to an external monitor, it means that there is a big problem with the display part.

4) The graphics card hardware is faulty, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, and there is no display on the screen. If the graphics card is broken, the average user can't solve it, and the only way to solve it is to find the computer's after-sales service. If the notebook is within the warranty period, it can be taken for free inspection and repair.

There won't be a problem with the hardware.,Reinstall win7.,It should be a problem with win7 piracy.,You can switch to the Apple system to try.,Then again,I think Apple's system is pretty good.,A lot of software is available now.。

You try it with OS X, if it's okay, it's your Win7 problem.

Isn't it normal for you to use your phone??
