Q: New Battery and it is not recognized and won't charge.

Jan 21, 2015 1:41 PMby my ginger,Do you have an X in the battery menu top right? At any rate you could try zapping your pram by holding down the command/option/p/r on startup and wait for the macbook to chime three times. If that does not work, then if you have the macbook with removable battery. Shut it down remove power cord and battery and hold the start button down for 5 to 10 second then reinstall battery and power cord . This is SMC reset. Restart Macbook and see if it is now charging. ON Macbooks without removable batteries, it's Hold down command/ option/ shift and power button for 10 seconds. You might hear a couple of beeps. Release and restart. If that does not work you have other problems. Coconut battery app is a good app to show what your charge and battery are doing. I have a macbook that does not show charge but coconut battery shows that infact it is,but at a very slow rate.

Jan 23, 2015 10:32 AMby dwest1935,Thanks... I have tried the SMC Reset... and nothing. I also tried the Pram reset which actually didn't work. I took the mac to the apple store. They ran a hardware diagnostic test on it and told me that the Battery and Battery Sensor (which is in the battery) was bad. All other hardware tested ok. I had a new battery overnighted to me from OWC (Other World Computing) and still have a battery with a X in it. Tried the SMC Reset again and nothing. OWC stated I may have gotten another bad battery?? However, if I unplug the laptop from the power supply while on... the mac shutoff and the sleep/hibernate light stays on. This tells me that the battery has power but my mac won't run on battery power. When I check the hardware in the software. It shows that my battery is not recognized. Still stumped...

If any of either side has debris or an obscured connection, this will
prevent adequate electrical contact from being made.
•Apple Portables: Troubleshooting MagSafe adapters - Apple Support
•Mac notebooks: All about batteries - Apple Support
•Intel-Based Apple notebooks: Identifying the right power adapter and power cord - Apple Support
•This also considers - if an update in existing software - may be needed:

Another connection issue could present itself should the MagSafe
DC-in Board (in computer) has became defective; as this would
require a service for the part to be replaced, if determined so...
The DC-in Board (equivalent) can be looked into, and it may help to see
the iFixit repair guides for MacBook models; find your specific one here:
https://www.ifixit.com/Device/MacBook
{Of course, the basis of most troubleshooting relies on the peripheral
or removable parts, cable, adapter, battery, to be known-good & OK.
So if OWC can pre-check their product before shipping, that'd help.}
Sometimes those SMC and NVRAM resets don't appear to change
anything, they could be performed more than twice without harm.
There could be another hardware issue behind this situation, or
there may be some other problem. Not sure if a detailed look into
the Console logs or the System Profile's power or energy info could
be of much help to a non-professional, who may diagnose from it.
Hopefully the problem will be overcome, perhaps a visit to another
Apple repair specialist, or an AASP with other testing measures?
Good luck & happy computing!

Jan 23, 2015 10:56 AMby my ginger,I had something almost like that with my wife's 2006 Macbook. Turned out to be the battery cable inside the laptop. It also would not run with power cord removed. But hers shut off completely. If this is the case with yours, i'm surprised that the mac store didn't find it. This battery cable inside the macbook controls the charge getting to the battery/ the battery running the macbook and sleep mode. It would be surprising to get two bad batteries in a row. The X means no battery found.
