HP laptop 15-ak085na - Blank screen after start, no response

Hi there,

My 15-ak-085na laptop just turned off during logging in to Windows.

Since then I have blank screen only, no response at all (even the caps lock light is unresponsive).

I've tried win+b and win+v combos, with and without bios recovery pendrive, "hard reset", cr battery change, disconnecting hdds, the dvd drive, main battery in and out, external displays. Memory module looks fine (after taking it out I have 2 short and 3 long caps flashes).

Any ideas anyone?

Thanks in advance!

DEK so you can see the BIOS etc? When does your screen turn/stay blank

Nope, all I can observe fans are on and hdd is starting up so from the mechanical noises side all fine, however even the screen backlight won't turn on, sometimes it "blinks" for a sec but will turn off immediately.

Tried to access at least the BIOS recovery with win+b/v , esc, etc. but no luck...
