Hi guys,

 

I have a Probook 450 G4. Today my battery went down and when I put it on charger it refused to boot up.

 

I get 2 long 2 short beeps, caps lock and num lock are blinking and the screen doesn't start. I checked this thread:

https://support.hp.com/us-en/document/c02693833#usbrecovery

 

Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps - I hear the usual beeps after which the fans start running on max RPM and nothing else happens afterwards.

 

Any ideas?

Is there anything I can do in that case? My laptop is out of warranty unfortunately.
