Hey all, My 17" MBP (2.4 Ghz Santa Rosa) has given me nothing but problems since I owned it. Recently my battery stopped holding a charge, and thus I could only get 15 minutes out of it. I figured since I had this battery over a year, it was time for a new one anyway. Last week however, I discovered that the battery was swelling up. It's at the point where it's swollen about 2 cm out the bottom of the laptop. I've ordered a new battery, but am still waiting for it to arrive. To be save, I've removed the battery, but have been noticing quite a few problems with my mac without it in there. The first thing I noticed is that my 3d video performance has halved. There was a time when I would remove my battery to keep the unit cool and didn't notice any performance hit. The second thing is my computer will not boot without the battery in it. When I hold down the power button, the led on my mouse and memory stick flash on and off as long as I hold the power button down. However, the computer will not turn on without the battery. If anyone has a same machine, it would be wonderful if they could test this. All you need to do is shut off your computer, pull the battery out, then try and boot the machine with only the AC plugged in. Thanks for your time.
