PPDCIN_G3H at lower voltage
Hi Everyone
I have a board 820-00165-A
The PPDCIN_G3H should be at 18.5 V , but it is at 14.90
I see that PPDCIN_G3H comes from J700, which is the conector to the I/O Board.
What would be the next step on this issue?

First of all, Is it powering on? If PPBUS_G3H is at 8.56 I wouldn't worry about it and I'd look elsewhere. Try a new DC in board and a KNOWN GOOD charger and it should be set. If it is still at 14.65 we can go from there but I don't think this is an issue.

PPBUS_G3H is in 8.58 so I would say it is within the range.
And the charger is proven to work Ok.
PPBUS is fine. 8.58 is perfect. Does the system power on?
No, and not even the fan
BTW I forgot to add that I have not tried switching the DC board.
I'm from a place where I have to wait at least a week to get the replacements. Should I go ahead an order it?
DC IN board is fine if it has PPBUS. U1900 area? PPvRtc_g3h present? PM_SLP_S4 present?
PPVRTC_G3H is at 3.42 schematics says it should be at 3. I'm not sure if that is within the range.
PM_SLP_S4 I measure no voltage if that's what present means

Do you remember how you solved this?
I have the same board with the same issue PPDCIN_G3H is at 14.4V and the laptop won't turn on.
The fan is spinning at low rpm and it looks like the SMC reset is happening (the magsafe LED is turning back green and then orange)
The history of the laptop is that it was working, I left it for a few months and now, it's in this state.
Thank you
