Hey Guys, Hoping you could help me with my current problem. I've been looking around and I'm not really that tech savvy so I don't know where to search or what to look for. Recently I've had this problem with my MBP, which I purchased last year (april) a 2.5ghz MBP with a 250gb hd. When I unplug it and use it, it would often shut off for no apparent reason. There are no Low Batt warnings and even with more than an hour left on the charge. Though rare, it would even shut itself while its asleep. When its plugged its perfectly fine, but then that kinda defeats the purpose of a laptop. This is quite disturbing and I really want to fix it asap. A visit to the apple center is a last resort since these coming days are quite heavy with a lot of school work and projects that I need my mac for. Any help would be deeply appreciated and if this has already been covered before, please point me in the right direction. Thank you very much!
