Blinking Caps Lock and Lit F12. Black/Blank Screen like literally NO POWER on screen.

[Moofenshmirtz]

I already tried the Windows Button + B/V and it didn't work. The Notebook's Original OS is Windows 7 and I upgraded it to Windows 8.1 (64-bit). NO POWER on screen. Unending Blinking Caps Lock and lit F12. Will the BIOS recovery flash drive work even though theres no power on screen. I also tried the "hold power button" solution but it didn't work.

@Moofenshmirtz,

Welcome to the HP Forums!

This is a wonderful place to converse with the community, get assistance and find tips.

I reviewed your post and understand that the computer is not booting to windows and the caps lock key is blinking continuously.

I'll be glad to help you 🙂

In order that I may provide you with an accurate solution, I will need a few more details.

• When was the last time the computer was working fine?
• Have you made any software or hardware changes on the computer?
• Have you performed any troubleshooting steps before posting?

While you respond to that, I would like to inform you that if the caps lock is blinking continuously it means CPU failure. However, I recommend you follow the steps in the below article and check if it helps.

1. When was the last time the computer was working fine?

Answer: Last Week, While I was playing the screen went White then when I turn the computer off the computer was fine again then the screen went Brown then when I turn it off again then I turn the computer on again and that’s where the issue started.

2. Have you made any software or hardware changes on the computer?

Answer: I installed an application called Driver Booster which updates your drivers.

3. Have you performed any troubleshooting steps before posting?

Answer: Yes, I already tried holding windows key and B/V. I also tried the hard reset/hard reboot but all of that didnt work.

Did you follow the steps suggested in the artilce I have shared in the last post?

Are you able to boot to BIOS? 

Here is how you can boot to BIOS.

- Turn off the computer.

- Turn on the computer and keep tapping the F10 key to boot to BIOS.

Let me know how it goes and you have a great day!
