Hello all, Do i need to get a new battery? here i am, trotting along at 40%-45%, running on battery power, sitting on the toilet and checking my email... and it all goes black. doesn't restart. i turn the computer over and press the little button on the battery, and nothing happens. no led's. i take the battery out to make sure it has not exploded, put it back in, and then it restarts. seconds later it goes black. no blinking lights on led. plug it in and it works.... any suggestions? a trip to the apple store and a free new battery? r.
