What should I do if my laptop screen is black but the power light is on?
If your laptop’s power light is on but the screen remains black, the issue may be related to the display settings or connection. First, try adjusting the brightness by using the function keys on your keyboard, as it might simply be a case of the brightness being turned down completely. You can also try to connect an external monitor or TV to see if your laptop is outputting video to a different display. If the external display works, then there may be a problem with your laptop’s screen.
If the external monitor does not work either, the problem could lie in the hardware, such as a faulty graphics card or motherboard. In this case, you may want to perform a hard reset by completely powering down the laptop, removing the battery (if possible), and disconnecting any external power sources. Wait for a minute, then reconnect everything and power it back on to see if the issue is resolved.
