I have a late 2008 MacBook Pro work computer. Here's the sequence of events:
- I fully charge the battery
- I unplug the Mac from the power cable
- The Mac immediately shuts down
Before unplugging the Mac, I press the battery power indicator button and all lights are green. When I unplug the Mac I press the indicator button again and only one light is green.
I've tried resetting the PRAM, SMC and even bought a new battery but the problem persists. Here is the System Information.
How can I get my MacBook Pro to stay powered on when not plugged in?
