Dim green light on magsafe, doesn't charge but boots fine if connected
I’ve spent the last few days browsing tons of posts about dim green light magsafe connectors but still haven’t found a similar case.
I’ve bought a MBP that had dried up thermal paste on the CPU and GPU which caused overheating. The charger was working fine, bright orange or green light.
I took it apart, installed new paste and after putting everything back together the charger will not charge the computer and will only have a very dim green light on the connector.
When I connect the magsafe power supply the light is very dim, even when the board is out of the case with nothing else connected. I do not see any corrosion on the board, or any damaged components.
An SMC reset does nothing
A PRAM reset does its thing but doesn’t solve the issue
Using Coconut, I can read the battery info (serial, temperature, cycles, etc), it sees that it is connected to AC and it also says that battery is not charging. It currently runs at 1.6% (74mah)
I tried a different power supply which works with another Macbook but I have the same issue.
I cannot find schematics of the one-wire circuit on this computer so I cannot verify the voltage (I dont know where the chips are).
Do you have any advice?
that’s all I currently have on my cellphone. Like I said in my original post, the computer can read the battery info.
I have tested with a known good adapter already and it shows the same behavior. I dont have a spare dc in board to test but I have already ordered one yesterday
here is a screenshot of Coconut with magsafe disconnected
Es esta una buena pregunta?
