Solved! How do I fix a laptop that turns on but the display won’t?

Feb 26, 2019
I tried to undervolt my ASUS F5551 and my laptop restarted. I can turn it on but it won’t display anything, I also tried it with an external monitor.


Take out the main battery and the CMOS battery from the motherboard if it has one, hold in the power button for about 30 seconds to kill all motherboard power and reset the BIOS. Plug in main power only and see if it turns on normally.
