I have a problem with charging of my Battery which has been appeared last night. It was working perfectly well for a long time. All of my friends who had different laptops were so jealous at my Macbook, because their laptops must have been plugged-in mostly to function well. I am worried that may laptop may being like theirs.


This is the case:
The battery is not fully charged. So, I plugged the charger to the power source, but the magasafe LED is green and only says Battry is not charging. I have tried to reset SMC (I hope I did it properly), but the problem still exist. Here is the battery status that you may find it helpful to assist me.

Thanks for sharing your knowledge

Problem Solved
The battery was fine and the problem was with the charger. It seems that the charger couldnt transmit enough power to charge the computer while it was in use.
I opened the casing of the charger and observed that 2 capacitors were swelled. I changed them with new ones (I found them in a video receiver). Now its working like the first day I got it.

Status says 'Check Battery'.
Looks like time for a new one, maybe?

Potential cycle count for that machine is 1000, & you're pretty near that figure.

  • So sad, It was working perfect till last night. Is there any way I can fix it? @Tetsujin – Electricman Feb 5 '15 at 14:27
  • If the battery is removable on that model, you could try [with it switched off] removing, checking connections, put it back. Or, has been known to work, turn the magsafe connector the other way up & make sure it's properly seated… & clean – Tetsujin Feb 5 '15 at 14:32

    I'd go see a Genius; while they're testing it they can decide if it's connectivity/PSU or a dead battery. – Tetsujin Feb 5 '15 at 14:48

    PS - That 'Power Adapter: (null) Watts' looks to be highly suspect. – Trane Francks Feb 5 '15 at 23:11

    @Electricman: I'd be inclined to run diagnostics on the laptop itself. If the Apple Hardware Test comes up roses, it would suggest that there is a failure happening in the charger. A Genius Bar visit or authorized repair centre would be warranted then. My daughter's Air wouldn't charge a couple of months ago. The tech at the Genius Bar tested the MBA and when it passed, he just gave me a new AC adapter without even testing the old one. The MBA is covered under APP, so if your system isn't warrantied, you'll probably have to pay for a replacement. – Trane Francks Feb 7 '15 at 0:07

Either you're using your laptop heavily or you need to upgrade your charger with higher power (e.g. from 65Watt to 85Watt) so it can charge faster.

This usually happens when you take/borrow charger from other MacBook Air and you'll try to charge your MacBook Pro (which could have Core i7 instead of i5).

You can click on Battery icon to see which apps are taking the most power usage.
