Looks like there is no damage, but there is some gunk (likely just flux) in the connector. As for your second question, to answer the opposite: the touchpad doesn't work when the battery isn't connected and the heat is NOT there. It was when the battery was plugged in that it wasn't recognized...
A Macbook Air (A1466) came in with water damage that had been cleaned and booted fine with working touchpad and battery, but C7114 and battery connector were replaced because of accidental breakage (while no power). Turning it on, the battery indicator had an X, cursor showed up but touchpad...
So red probe to ground for resistance mode, continuity mode, and diode mode, and black to ground for voltage modes? And is there a way I can find the capacitor without a power supply?
Well darn; I don't have a lab power supply. Although as for the coils, can you make sure I'm sure, so to speak:
- Put red on pin 1 of each, black on ground
- On some of the coils, it took about 10 seconds or so for the reading to stabilize
Is there any other way to find it?
Using that strategy:
L2920 pin 1: 947 Ω
L7310, L7320 pin 1: both 17.2 Ω
L7560 pin 1: 5.25 kΩ
L7520 pin 1: infinite
I suspect I misinterpreted your request.
Yep, just checked on resistance mode with F7140 and it's in the MΩs so that's definitely going to have to be replaced. Although actually when I reverse the black and red it's just 1 kΩ. Before I go forward: you mean place red probe on, say, F7140 pin 2 and black on ground in resistance mode with...
L7130: ~1.0 kΩ
CHGR_AGATE (pin 1): 3.3 mV (0 V)
CHGR_DCIN (pin 2): 14.6 V
CHGR_ACIN (pin 3): 3.96 V (measured in DC but the name suggests AC?) 0 V measured in AC
CHGR_AMON (pin 9): 29.5 mV
PP3V42_G3H (pin 12): 3.468 V
CHGR_RST_L (pin 13): 3.3 V
CHGR_BMON (pin 15): 55 mV
CHGR_CSO_N (pin 17): 8.6...
P3V3SUS_EN is 0, PM_SLP_SUS_L is 0, and that comes out of the CPU which seems concerning. PM_PCH_SYS_PWROK is 0, ALL_SYS_PWRGD is 0, PP3V3_S0 is missing. Sorry that might be too much info - followed it from P3V3SUS_EN as you can tell but got a little stuck at PP3V3_S0.
PP3V3_S5: 0.5876 V
PP3V3_SUS: 0.0 V
Still get orange light with charger. Does that mean the short, which caused the spark and noise, didn't break anything?
