Re: HP FPW50 LA-H323P have anybody schematic or BV?



Sorry to bother you but I'm trying to repair one of these boards and appreciate you taking time to post this information. The board I'm trying to repair is missing the +0.8~1.1V rail. I checked PQA1 and I do have 20V on the high side but only 0.2 on the output. I thought maybe I'd get lucky and it was just the FET so I swapped it with PQB1 as I had 3v out of it without a battery so I knew it was working. No change at all.

History, this board was working fine until I opened it up to upgrade the NVME....
