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.

Take the back off your mac and check to see all the ribbons are undamaged also check to make sure the the ribbon connectors are not cracked twisted or broken its a common problem when unplugging the battery to damage the connector they are very delicate and require a very light touch. I've had battery problems before these are my steps I know you have probably tried already but if your desperate it might be worth trying again. Its not really relevant if you can't boot because of no charge. The idea is a normal battery would not suffer much impact like this in short term use but a dodgy battery would be very sensitive. a logic board problem would make no difference if you get my drift.

either of these situations confirm a battery problem in a case of less or more charge. blue tooth fire-wire thunderbolt SD CD and DVD drivesĭisabling OR enabling as many as possible and changing the settings to low power or high performance should make it last longer or less long. they can run hot and burn out it might be possible to have 2 broken units.ĭisabling or enabling devices that use power can be used to diagnose a battery problem e.g. PrioritizeNetworkReachabilityOverSleep: 0Ĭheck the ac/dc adaptor with a multi meter it should match the writing on the unit.

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.

I have replaced the battery with a new OEM battery, but this did not solve the problem.

I just replaced the battery with a new OEM battery, no change.

I have 2 chargers, both exhibit the same behavior.

Macbook will not power up/respond with charger connected and battery removed.

Current battery charge level remains relatively unchanged as long as the computer is being powered by the charger.

Macbook is being powered off of the charger.

I have a Macbook Pro (Mid 2012) 13' unibody and having issues with a battery that is not charging.
