Why is my MacBook not drawing power from the (new) battery?
Suddenly (about 8 weeks ago) my Macbook stopped working when the AC-Adapter was not plugged in. When it was, every worked fine, the battery would even charge to 100 %, vbut as soon as I unplugged it, the power would go completely off. I have since tried the following:
- purchasing a new charger cable (offbrand)
- install a new OEM battery (bought it from iFixit)
- replaced the I/O board.
Now my Mac says "replace now" in the battery status dialogue, and is still only drawing power from the charger, not from the battery. Same effect if I switch to the old battery, so the initial problem is still not solved. Of course I have reset the SMC (multuple times both with the device powered and not powered) and the PRAM.
Any help is greatly appreciated!
Is this a good question?
