Hi,
I have an A1534 820-00045-A that has no power.
With one side of the charger conected, the ampmeter stays full black. If I switch the side of the power cable, the ampmeter just blinks.
On F4700, when the ampmeter blinks, I only get 2.5-7 V
F4700 diode value is ok (0.554)
E85_CC1/2 diode values seams to be ok (0.547).
CHGR_LDO_VDDA/P diode values also seams ok (0.445)
Should I replace U4700?
