Black screen on the notebook even after system Recovery

[H8W8]

I have an issue with booting my notebook Pavilion dv6. It started several days ago when my notebook lagged (it didn’t respond to anything) and I performed a hard reset. Then, I reloaded it, but appeared black screen for ages after Windows logo. I reseted it again and I see a message “Windows failed to start” and an option to make a repairing or smth like that. Still, it didn’t help, neither resting to the last stable version. The problem stayed. However, I tried safe mode and it worked. Then, I decided simply perform a system recovery (reinstall Windows), but the problem was the same, but now I cannot enter even in the safe mode, cause I cannot perform a first launch after installing Windows. I tried recovery from my recovery disks, but it didn’t help.

Then, I ran system tests - everything was fine(see screenshots).

Then, I tried to recover BIOS, but in system diagnosis I have error “failed reading bios image”, but I can go in bios by pressing “esc” while booting notebook.

May be you have any ideas what can cause this problem and how I can solve it?

Hope, for your fast response

Is there a battery in it or not?
