Re: MacBook Pro 820-3115 G3H missing



Hi there,

Sorry for the delayed response, I've been busy with work.

I've attached both the schematic and boardview ...

Re: MacBook Pro 820-3115 G3H missing

Just updating after some probing.

Pins 27 and 28 of U7000 both have no resistance.
C7030 and C7031 are also showing as short in diode mode.
Q7085 does not open even though there is a lesser voltage on the gate.

I hope this helps anyone who can make more sense of schematics than I can

Thanks very much.

Thanks very much for the response.

My resistance to ground on PPBUS_G3H is 0.840kΩ....

Hi all,

I'm new to the forums and was pushed in this direction based on recommendation from friends and also YouTubers in the repair community.
Please excuse my ignorance as I'm new to Apple repairs.

I've got a 820-3115 that I purchased as faulty. The laptop obviously had a repair attempt previously and there are signs of widespread liquid damage.

I'm getting no PPBUS_G3H created on the board.
I have PP3V42 across the board.

My input voltage is around 16.6V at DC in. The schematic shows that I should be getting 18.5, is...

Hi all,

this forum was recommended by multiple YouTubers in the repair community.

I've signed up to the forums because it's recognised as a great resource for finding schematics and just seems to be a very helpful environment in general

I'm Joe, 23 from England and have only just got into microsoldering. At the moment I've got very basic kit that does the job, but will certainly upgrade if I ever decide to monetise my repairs.

I look forward to getting stuck in!
