Hi,
I have got 820-2914-a that is not turning on. No light on magsafe. Checked ISL62 and it seems be ok. Reistance between 17/18 and 27/28 is fine.
PPBUS is los 1,7V
PPDCIN_G3H is fluctuating from 16,8 to 17,1.
Checked resistance arroung ISL and also didnt find nothing wrong.
PP3V42_G3H - 3.45V.
Before checking S3 and S5 lines. Is there any idea why it is fluctuating if ISL and all componentes arround are ok?
Thanks
