How to fix laptop coming on but no display
If your laptop is turning on but not displaying anything on the screen, here are some steps you can try to fix the issue:
Check the power supply: Make sure your laptop is properly charged or connected to a power source.
Check the display brightness: Sometimes the brightness settings on your laptop might be set to the lowest level, and that can make the screen look like it's off.
Check the display connection: Check if the display cable is firmly connected to both the laptop and the screen.
Try an external monitor: Connect an external monitor to your laptop and see if it displays anything. If it does, then the problem might be with your laptop's screen.
Restart your laptop: Sometimes restarting your laptop can solve the problem.
Boot your laptop in safe mode: Try booting your laptop in safe mode and see if the screen displays anything. If it does, then the issue might be with the graphics driver.
Update the graphics driver: Try updating the graphics driver on your laptop.
Reset the BIOS: If all else fails, you can try resetting the BIOS to its default settings. This can sometimes solve display issues.
If none of these steps work, then it might be time to take your laptop to a professional for further diagnosis and repair.
