yes, this is the one. This is actually my friends laptop and it's out of warranty. I am pretty sure that mobo is bad cause it was known issue on these models when sound card winch is integrated into motherboard dies due to overheating. I think i can replace it myself, I've disassembled laptops before to clean radiators, so it is not smth incredibly complicated. I just need to find mobos part number to be sure i order right board. I couldnt find any information about motherboard model on hp website so I've decided to ask the community.
There is a sticker with 2 numbers under ram sticks, looks like cpu and motherboards SERIAL numbers not part number...
