Have an A2442 that suffered a lightning strike, unit would not power. Replaced 2 IC, UG400 and UG800; UG400 had a hole in it and UG800 had traces 2, 6, 10, 14,18 and 22 burnt off the board.
Repaired the traces under UG800 and replaced both IC, unit powers on now. MagSafe shows light and makes chime when plugged in, USB C makes chime when plugged in.
When on the login screen the battery doesn't show the charge icon when its on charger and it charges super slow. Left it over night and battery charged full.
Unit will not turn on with the battery unplugged and i don't have a extra battery to test with.
Measured the following without battery plugged in:
PPBUS_AON- 12.05v
PP3v8_AON- 3.8v
J5101
Pin 3- .65v
Pin 5- 0v
Pin 7- 0v
Pin 9- 0v
Pin 11- .45v
I mainly repair game consoles, but have a little experience with MacBook's, I'm just kind of stuck at where to look now.
Thank you for any help.
