Hi guys, I have this mac that does not turn on, green led for 1 minute and then orange. I had an absorption of 0.22 and after replacing u7100 it dropped to 0.8. but still does not start. Some idea?
Then is safe to inject voltage, if short remains on PPBUS_G3H.
Start with 1V and go high slowly, if needed.
Set first the lab PSU amp limit to max.
Probably a big cap will heat on PPBUS_G3H.
