HP ProBook 440 G3: Laptop will not power on; blinking caps lock and num lock with beep

Wed, 11 Sep 2024 20:31:53 -0700

I have a HP Probook 440 G3 that refused to boot after a failed update. 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.

i guess is shorted board?

I guess not the charger, board has the 19volts on it. It is posible RTC cmos battery affect it? Theres a 0.20volts detected on the battery pins is it normal?
