We expect the technology in our life to work every time we turn a machine on. It's terrible when they don't work, especially when we don't know how to solve the problem. You turn the machine on, but see the black screen.
A computer screen that doesn't turn on may be a sign of a broken screen or a bad connection between the computer and the monitor (显示器) .Trying another monitor or connecting line is a simple way to see if one or the other is broken-down.
For windows users, they could face a system files corruption (损坏). Turning on your computer, you might see the black screen and words on the screen remind you the corruption. In that case, you may need to restart your computer and enter the recovery mode (恢复模式) 。
In that case? you need to open the computer case and clean the fan.
Apple's iOS users might need to restart their phones, though the method differs depending on the model. If you are a owner of the iPhone 11 or a newer model, you can press and let go of the volume-up and do the same to the volume-down button, then press and hold the side button until you see the Apple logo.
If the problem keeps occurring, you'd better have a professional (专业人员) take a look at it.
