Re: HP OMEN 15-DC no power/charge


I removed the suspect S88P15 capacitor => Short still present
Update after S88P15 removal (board damaged) => Short still present.
Locating the short on the backside, unfortunatelly, the Chispet seems to be the cause.
End of Troubleshoot and repair attempts.

Re: HP OMEN 15-DC no power/charge

I already brush the board with a teethbrush + dry air in the dense components area. => No effect (even if that does not replace microscope inspection). Board looks really clean (No liquid or damaged component). Unfortunately I don't have Microscope.

What do you think of the overheating component ? Is that a good path ?
I think this short make the 3.3V to fall down.

Hello,

First attempt on MB Troubleshooting (Beginner here )
I bought this HP OMEN for parts with a faulty MB.
OMEN PN : 15-DC0997NF

Important points to notice before to start with troubleshooting : I got this unit without charger (specific 200W/10.3A for this model) and without peripheral components (RAM, WIFI, SSD, HDD).

I am currently using a 65W HP charger to check the MB. Want to know if I can recover this MB before investing in an expensive charger/RAM. And maybe that will become a problem in the next steps (If I recover power).
