Machine boots fine.
ASD says battery may not be charging correctly

FAN maxes out and stays there at 6800 rpm always
Installed Hardware monitor

Battery temps : 129 C in hardware monitor
The battery temps are the only temps that are high
all other temps normal



this is a water damaged air
I already:
replaced trackpad, trackpad flex cable
dc in board
flex cable for dc board

Other problems?
R6950 or D6950?


looking at page 44 sensors
It looks like the transistors like Q5830 are acting like sensors?
Q5810
Q5830
Q5860
seem to be battery monitor sensors/ddr sensors

I don't have another IO flex cable and the one I have is red on the water damage indicator
I'm going to get another one.

Yes the fan was running high without the battery connected.

OK new flex cable and DC in board.
Connected battery.
Boots to OS.

The 128C battery reading is gone.
but
Fan still at 6100 RPM-6300RPM
Machine seems a bit sluggish

The PECI SA sensor seems to flip between 0C and 38 C.

Next I will try to use a new trackpad. I used a known working trackpad.
