before, when i would turn on my hp laptop the caps lock light would light on twice and laptop would turn on, now it only lights up once and it blocks, screen stays black and the only way to turn it off is to pull the battery out...what should i do?

Hi,

Please do try these troubleshooting steps that may help in solving the issue.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then see if it will boot up normally.
- Next to try to boot it up with just its AC adapter and see if it will boot up normally every time you turn it on.
- If these doesn't work do also try a different AC adapter that has the same voltage and see if the same problem will persist or not.
- Finally, do clean the inside of your laptop making sure there's no dust on the fans and apply new thermal paste on the CPU and GPU as well.

Hopefully this will help.

What is the model of the laptop?
Does the Caps Lock and Num Lock blink or just the Caps Lock?
Do the blink continue every few seconds?

Thanks for your help, but I replaced screen from my sisters laptop to screen of my old HP.
