CPU: I7-4770HQ 2.2GHz

I'll attach its original BIOS, its act weird. Maybe anyone can help with repair. Its starting once, when battery unplugged and i connect charger. When the charger stays connected and i press restart, or turn it off and press pwr buttom its do nothing. Its 100% an EFI fail.

Thanks for help! : )

Oh, sadly the file you edited its larger.
Its 8 396 120 byte, so its complaining "Some date out if memory size"

I deleted some dead line in the end of the code, so its now in the exact size. 

Testing now. : )
