It started emitting the num lock LED continuously a week before this incident.

On pressing power, it doesn’t boot but caps lock and num lock blink with 2 long beeps and 2 short beeps, then the sequence continues endlessly without the beeps heard. I have accessed the support on the HP official website to attempt restoring the BIOS but it is not helpful.

Please anyone with similar experience and how did you solve yours?

Grateful for your inputs.
