Can't start my HP probook 450 g3

HP Recommended
HP probbok 450 g3
Microsoft Windows 10 (64-bit)

Huh, I have tried everything what is possible to find on the internet...

Removed all devices as RAM, keyboard, touchpad, wifi, hdd, ssd, battery, AC power...

Nothing helped..

 

When I try to turn on my laptop, just caps lock and num lock buttons are blinking 7 times and that is all.

 

I can't run my BIOS at all, tried Win + B also. 

Tried to remove CMOS battery for some time..

Tried another battery..

 

Can anyone help with this?

You have done all the troubleshooting any technician could. Unfortunately you have a dead motherboard. No other logical conclusion.

Hey Huffer, thanks for the reply.

 

Any chance that maybe CPU is dead or you are quite sure that motherboard is?

 

Thanks.

Since the processor is not socketed and is soldered to the motherboard makes no difference.
