HP Pavilion x360 Convertible caps lock blinking 3.3 issue PLEASE HELP

HP Recommended
HP Pavilion x360 Convertible

Hello, gonna keep it short and simple.


Serial number:


Product Number:




Have a HP pavilion x360 convertible. 

No power, caps lock blinking issue 3.3 (3 slow, 3 fast) suggesting graphics card / video failure.

Reset BIOS using USB, No luck.

Very comfortable with ins and outs of a laptop as I build many custom laptops.

Doesn't seem to be an issue with motherboard unless the CPU is dead.


Any solutions to this?






Seeing a lot of comments from weird individuals who in trying to sound overly clever, are very rude in their approach, so If I see those typical snarky comments as is common on tech sites; get out of your basement and make some friends 🙂

Thank you for posting on the HP Support Community.


This sounds like hardware related issue with the computer as it's not powering on. 


I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically. HP Support can be reached by clicking on the following link:​​​​​​​
