Hello Everyone,

My laptop was working fine last night, but, the system would halt on the hp logo whenever I restarted my laptop. A friend suggested to update my BIOS to the latest version and I successfully updated the BIOS. After that, the problem was still there and I was unable to restart but this time even shut down caused the same problem. I had to open my laptop and disconnect it from the battery. After re-inserting the battery a while later, the laptop turned on and the diagnostics were passed. But when I shut down and tried to turn it on, the same problem occurred again. Now I am unable to turn it on even after removing the battery.

I have already tried to turn on while pressing winKey+B+Power button for a second, but no success. The hard reset also not working.

Please help me out. Any help would be really appreciated.

 

Best regards
