Battery not charging, slowly draining?

Question

Battery not charging, slowly draining?

I have watched my battery slowly drain while it is plugged in and now it is at 95 percent. It was never an issue before I upgraded to Yosemite. It would always charge to 100% but now it will not.

My MacBookPro (13 inch late 2011) has been plugged in the entire time I have been using it over the last few days, yesterday it was at 96 percent. Can anyone explain to me what is going on, and how do I fix this?

Thanks!

MacBook Pro (13-inch Late 2011), OS X Yosemite (10.10)

Hey there FarmGirlShelley,

If your MacBook Pro is not charging at all at this point, I would recommend using these troublehsooting in the following article:

Mac notebooks: All about batteries - Apple Support

My battery is not charging

Confirm the correct wattage AC adapter for the computer. A power adapter rated for a lower wattage than is required for the system may not reliably charge the computer. For assistance identifying the proper adapter, review Intel Based Mac notebooks: Identifying the right power adapter and power cord--US. Additional adapter troubleshooting is available in Troubleshooting MagSafe adapters. If issues persist please reset the SMC.

Thank you for using Apple Support Communities.

All the best,

Sterling
