I would like to ask you for help. I cannot run my laptop Pro Book 450 G3. The caps lock nad num lock just flashing 7 times and nothing more happens.
I did not find the explanation for the codes here: https://support.hp.com/us-en/document/bph07107.
There is no explanation for 7 times blinking of caps lock and num lock. There is just "Power button LED blinks 7 times with 7 beeps", but Power button never blink - just the caps lock / num lock.
Do you have any idea what is the issue, or how to fix it?
Thank you for any idea.
I treid to remove the bios battery but it did no help.
I've tried many things but nothing helped.
