Been a while since i needed help, but here's one that's been bugging me for a couple of days.
820-3332 that had some damage due to probably a knockoff charger, had to replace R6920,R6905,D6905 and basically carpetreplaced a lot of things around U6990.
Got it back to life, works perfectly, only to notice in final testing that the fan would occasionally run high out of the blue (when machine is just sitting idling).
Ran ASD, and noticed that when i run the sensor-tests while connected to AC (Genuine 85W Magsafe 2), all sensors pass, however, running the same tests off of the battery, the ID0R sensor fails.
It's reading 4,080A with charger connected, and reading 0.000A when only on battery (it should read between 0.65 and 4.671A according to hardwareprofile in ASD)
I've searched here and found a couple things i've already tried so far:
Replaced R5441 and C5441 together,
Checked continuity from R5441 pin 1 to U7000 pin 9: checks out.
R5441 pin 1 reads 0,45V
Checked currentsensing by the ISL and for the heck of it replaced the ISL twice.
R7021/22 check out and their traces to both R7020 and ISL appear fine.
Just finished replacing the SMC as a final check before asking here.. No difference.
Any other ideas?
Thanks in advance!
