I picked up this no power OLED switch, only to find it took power- great! Then it charged enough to boot, and hung on the logo- I tried a different battery, both charged & booted the same. When it hangs, the fan never spins- and draws a constant 12v .88-.90a until forced off. With nothing obvious on the board, I changed out m92, with no difference. Then I thought maybe the fan was connected through m92 AND p13, so I swapped that out as well. I got excited when I plugged the board in- instead of no draw, it was going .04-.08-.00, it did it twice in a row so i thought I had a boot loop.
I re-assembled… and back to square one. I’m stuck. Anything anyone seen before that can point me in a direction?
