Hey, my dad's got a 2007 2.4 GHz core duo white MacBook, and I think he might have a bad battery, but we're not sure and I thought I'd ask around here. The entire lower portion of the top part of the case is running hot, and a light touch anywhere on that panel, from just below the fn key to the right arrow key on both sides of the trackpad, will cause the mouse to jump, things to be clicked, etc. On the bottom of the case, the battery compartment has swelled and bowed. It's jutting out on two sides and is also running hot. My dad tried to unscrew the compartment to take a look at it, and the screw broke off. Is this a widespread problem with these models, or is this something fairly unique? Is it dangerous, or just annoying? Is my dad going to have to completely replace his MacBook, or can this be fixed with a new battery/case/something else? Thanks in advance for any help.
