HP Windows screen black and caps lock flashes twice.


Sep 8, 2017
I turned my laptop off to save power cause I needed to use it later and I didn't have the charger. When I turned it back on the screen was black and the caps lock was flashing twice. I tried the key method to restore BIOS but it didn't work.
Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
