Battery not charging on old non-unibody


Just inherited an old MacBook Pro 15" non-unibody (A1211) from a friend. The original battery had stopped working, so I received it without one. Bought a cheapo on Amazon and it powered up, but when plugged in it displayed "not charging" by the battery life. Returned it and bought another less-cheap one. Same result. Friend says he never had that issue but that it did sit unused for about a year before I got it. Assuming it's computer-based at this point, and not two bad batteries in a row. I believe the charger is a non-Apple model, but again, worked fine before. Any ideas?


Update (12/18/2016)

I've also noticed that plugging/unplugging the charger results in brightening/dimming of the display, so it seems to at least recognize the charger...not sure if this helps anyone diagnose.

Any way to confirm that the charger is working properly? As I mentioned, it *was* working when it was put on the shelf a few years ago.

Try performing an SMC reset and see if that helps.

More information on how to do it here:

Instructions from website as follows:

If the battery is non removable

1. Shut down the Mac.

2. Plug in the MagSafe or USB-C power adapter to a power source and to your Mac.

3. Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.

4. Release all keys, then press the power button again to turn on your Mac

If the battery is removable

1. Shut down the Mac.

2. Disconnect the MagSafe power adapter from the Mac.

3. Remove the battery. (Learn about removing the battery in MacBook and MacBook Pro computers.)

4. Press and hold the power button for 5 seconds.

5. Reconnect the battery and MagSafe power adapter.

Hello. Maybe you have had bad luck wheb purchasing. But a possibility could be also when you had the damaged battery in it. It could have damaged the charger.

Do you mean that it could have damaged the actual charger that goes into the wall, or that it could have damaged some charging component(s) inside the computer?


They are both possibilities. Sadly
