Acer Nitro 5 (AN515-54) No charge No power
Hello all,
I'm working on an Acer Nitro 5 (AN515-54) with motherboard EH5VF LA-501P with a short on the power rail.
I'm just learning board level diagnostic, but here is what I've found so far.
I injected 1.5v to one of the positive leads on the DC jack connector (PJP101) and read about 1.4a to ground.
I felt around for heat and found the MOSFET at PQB12 is rippin hot!
when i pulled the MOSFET from the board the short went away. In my mind it was a faulty MOSFET.
Ordered a replacement and got it installed only to find it gets very hot again and the short returns....

Hello all!
I'm a repair tech in Idaho and I'm here to further myself in board level diagnostic and repair.
I've been in and around IT and device repair for some years now, but just in a the last year or so have really found that I love board level repair.
I'm still very much a novice but I'm taking in as much information as i can!
Thanks for reading!
