Macbook Pro 13 inch early 2011 doesn't charge. Green light. Turns on with charger!

Could it possibly be the charger? (Because of the green light). Could there be a situation where a charger is not charging but at the same time powering the macbook? Or is the charger just passing electricity to the max?

Interestingly, my old 2010 17" MBP that my son has been using was behaving like that this morning. The light on the MagSafe charger was green, unplugging it then reconnecting it, it stayed green. The battery indicator on the case showed one flashing green light (i.e. nearly out of charge). MacOS showed ~5% battery and that the power source was Battery. An SMC reset did not help.

I connected the Mac to another power supply, and 2 seconds later the indicator light on that one went from green to orange. It's been a couple of hours now, the light is still orange and the battery indicator on the case now shows the battery is about halfway to a full charge.

So, you may want to try a different MagSafe adapter (if you have or can borrow one), or buy a new one. If you take it to the Genius Bar, they can try one of theirs.

You may have a defective battery even though it shows as good. Or you need to remove and reseat the battery cable. Worse case would be the logic board. I'm going to try and insert a pic of what should show up in about this Mac-system report -power.

You could try a reinstall from recovery. But I am starting to think this is a hardware problem.

I suppose it's possible. If you did the SMC reset that may have also woke it up. In About this Mac-System report- Power, you should look at full charge capacity and charge remaining. If it's fully charged they should be the same. If it shows a low count you might need to replace the battery. Also look at voltage, sit should be around 12222 then down near the bottom of the report it shows your Mag Safe power supply, which should show 60 watts.Determine battery cycle count for Mac notebooks - Apple Support

Anything is possible. But you would have to try an known good charge cable to know that. If you look at the very bottom of my screen shot it shows the charger.Which in my case is not charging because my battery at the time was fully charged. But it shows as putting out 60 watts.. Which is what it is supposed to do. In rare cases your MagSafe connector on the laptop could be defective. but that is rare. You would have to let the Apple Genius Bar check it to know.

Try restarting, but hold the Command Option Shift key down while pressing the power button for 10 seconds. Then let it boot up. Can you run the MacBook Pro on battery only? Go to about this Mac, top left the apple click on it. About this Mac system report-Power. Look under charge information. Fully charged -charging- charge capacity- cycle count -condition.. If coconut battery shows above 90%, like 97-98% your Mag Safe my show green. If your MacBook Pro will run on battery then it has a charge.

If the battery per the computer really is at 0 or 1% then if you disconnected the MagSafe power cord, your computer would immediately shut down. Does it?
