MacBook Pro repeatedly shutting down after battery replacement
I recently replaced the battery for my Mid-2012 MBP using the iFixit battery replacement kit and instructions. Everything booted up without a hitch, worked great for about 2 hours, and then shut down randomly.
I've been able to reboot using my magsafe charger, and then unplug and run off battery power. However, this only works for about 10 minutes before the computer acts as if the battery is suddenly disconnected and shuts down again.
Things I've already tried:
- SMC reset
- PRAM reset
Anyone have suggestions? Thanks in advance!
