L7560 measures .68. 3V3_SUS = 0 Thank you.

Those measurements are when no magsafe light is present, and with only DC in connected. Does not start in SMC bypass mode. P3V3S5_EN_R measured at R7552 is 3.44 PM_RSMRST_L = 0 PM_PWRBTN_L = 1.56, when shorting R5115 drops to around .3 or .5 and goes back to 1.56

MacBook Air, 820-00165-a. Occasionally have green / orange light when good charger is plugged in. Board has no visible signs of liquid damage, but customer did admit to using a generic charger. PPBUS G3H is 8.64 as measured at F7140. PP3V3_S5 = 3.32 measured at C5126 PP3V3_S4 is .4 measured at...

820-00281-a (MacBook Pro "Core i7" 2.6 15" Touch/Late 2016). No signs of life. USB C power meter shows 0 amp draw on all ports. No signs of liquid damage. How to go about diagnosing this? Thank you.

Most of the corrosion was in the area of Q7310 (legs and pads are gone on one side) & Q7311, and a small amount on the other side near C5629. Board has been UC'd. How to handle missing pads for Q7310?

Hmm, considering the cost of replacement boards for this model I'm willing to sink a bit more time into it. How might I go about trying to determine if it is indeed a broken trace vs dead CPU?

Damn, it was working previously even though the CPU mount was busted. I guess epoxying it to the board & then applying power fucked it over? Nuts.

MBP 820-3662 board. It had a bad battery and would only run off AC power but was otherwise OK. Also checked the logic board and found a small amount of liquid damage near DC in board (C8324 & surrounding), and a bit more under the tape at C7372 and C7378, and the CPU screw mount next to C1099...
