Hi guys,
A friend tried to upgrade to SSD and he did something that killed this mbp,
I noticed that PP3V3_S5 was missing and that U7200 gets really hot. I replaced u7200 and it gets hot again. There seems to be no short on that line and diode mode at L7220 measures 0.089.
If I connect the magsafe and after U7200 gets hot (10-15 secs) this line gives a zero diode mode reading (magsafe disconnected of course).
Since there is no apparent short injecting voltage would be pointless?? Any ideas?
