1. Check whether the power connection is normal: check whether the computer power cord is plugged in and connected to the computer properly. If there is something wrong with the power cord, it may cause the computer to turn on the black screen.
2. Restart the computer: Press the computer power button to restart the computer. Sometimes the computer screen will get stuck, which may be solved after restarting.
3. Check whether the monitor is connected correctly: check whether the monitor cable of the computer is inserted correctly and ensure that the cable is connected with the monitor and the computer normally. If the cable is not plugged tightly or loosely, the computer may also have a black screen.
4. Enter Safe Mode: If the computer keeps displaying a black screen, you can try to enter Safe Mode, press F8 during startup, and select Safe Mode in the advanced startup options. In safe mode, you can try to run the system's own fault detection, or change the driver of the computer, or solve other problems.
5. Check hardware problems: If the above methods are ineffective, then the black screen problem may be caused by hardware problems. If you are not a professional technical engineer, please disassemble the computer carefully. It is recommended to contact the computer repair center for help.
Notebook hard disk
The performance of hard disk has a vital impact on the overall performance of the system. The bigger the hard disk, the better, because the bigger the hard disk, the longer it takes to search for information. At present, mainstream notebook computers are generally equipped with large-capacity hard disks, which can ensure sufficient space for mobile office. For users who need to surf the Internet frequently, in order to store a large number of hard disk buffers and downloaded software, this capacity of the hard disk should also be sufficient.
However, if you need a laptop instead of a desktop computer, or if you don't have any backup devices, such as CD-RW or ZIP, and you often make some multimedia presentation files, you can choose a hard disk with a capacity of 250GB or 320GB, because files such as sound, images and animations need to occupy a lot of hard disk space. Of course, if you pay great attention to the performance of hard disk, you can choose a powerful TB-class super-capacity hard disk.
