But just wait for something to happen, mac batteries have an issue where they can get all screwed up and need discharging and this is how I would fix it. if after a while nothing happens plug in the mag. before you plug it in the mag hold down the power button to 15 seconds or longer, something should happen a beep, a flashing light so just wait. Then close your mac back up and screw it back together. (trying to discharge the mac battery while the mains is plugged in won't discharge the battery).

I would disconnect the battery from the logic board and leave it for 15 mins then be very careful to firmly plug it back in using even pressure so all of it is plugged in evenly, be very careful. When unplugging them you cant just flip them out they need even pressure from each side and the middle and gentle levering very tiny amounts at a time if you are in the habit of flipping them out you may have inadvertently damaged them, if you think you may have been careless with the connectors you can get replacements inexpensively and this is a common issue on the mac.

So, my more specific question would be, based on the information I have provided, is if the issue can be narrowed down or isolated to a particular part or area of the system, and/or if there are any other possible fixes or troubleshooting steps I can attempt?īelow is the full text of the system power report: The next step would be to replace the DC-In board, but I wanted to see if I can get any more specific insights before I go throwing more $$ at the problem. I have also tried doing an SMC reset and a battery recalibration (remove battery, wait 5 seconds, plug in Magsafe, hold power button for 5 seconds, etc.), but none of the common possible fixes have worked.
