Battery not charging after changing thermal paste
I have changed the thermal paste and upgraded the RAM of my two MacBook Pro "13 Mid 2012. Everything seems to go OK, except for one of them. After mounting everything in the right place, the computer boots normally, but the battery does not charge. The led in the charger doesn't light. I have checked the battery connection and seems OK, even if I unplug the charger the computer continues running with it charge.
I have also reseted the SMC.
Might I have messed something from the DC IN?
Thank you in advance.
Ist dies eine gute Frage?
