Hello,
i got another problem with an 820-2330. The board has no green light. I cant measure any Voltages i want. Nothing at DCIN Fuse, no PP3V42, no SMC_BC_ACOK or PPDCIN_S5_CHGR. So i don´t know what to check next. Could it be the SMC?
I noticed, that after i plugged my charger in i need to completely unplug it from the wall and wait few seconds until the charger will work again with a good board. If i once plug it into this it´s like a dead charger. But at other Boards it works perfectly fine - no unplug from wall needed.
I measured Adapter_Sense witch jumps between +0,000V and -0,000V. At the moment i plug the charger in (only if i unplug it from the wall before, of course) i can measure at pin 1 & 2 of J6900 a spike of 0,384V for a second. Thats the only sign of life from this board. No evidence of water, soldering etc.
Thanks for any help!
