Why do I need to short-out my charging port to get my MBP to charge?
Here's an interesting situation...
I thought my MBP was dead. When I attach my 85w (or any) power adapter to the charging port I get no indication of charge. I get nothing at all.. no green light, no orange light, no blinking lights. nothing. That is until I found out that if I carefully angle the power adapter to connect one magsafe board contacts to the body of the computer (a little spark occurs) the computer will charge soon after.
This is very frustrating only due to the fact that if I short the contact while the computer is on it will kill all power. It makes being mobile very difficult because if I need to re-charge the computer I have to shut it down first, short it out, boot it back up and update my date and time settings. I have since replaced the magsafe board and the battery to try to remedy this to no avail. It seems to me the issue resides within the logic board. a grounding issue perhaps? Is there any wisdom in the realm of macbooks and electricity out there that can point me in the right direction to a potential fix? I would hope, at the very least, to gain insight on what exactly is happening (technically).
I should also note that the computer will only charge when I use my 85w adapter.
