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 this something to worry about?
After looking the machine over initially I came to the conclusion that I needed U7000 replaced for the OneWire circuit to function. After replacing U7000 I get a green light on the charger, but only for 5 seconds! The green light then disappears for a while and then comes back for 5 seconds.
Again, I'm sorry for my ignorance here, but I'd really appreciate a push in the right direction.
Thanks in advance for your help and I look forward to your responses!
-Joe.
