One of the batteries in my wife's Dell Latitude D810 is stuck in place.
It doesn't budge a bit when I try to pull it out. It's the battery that
fits in the right-hand-side, where you can also put in a CD drive. The
case is bulging down a bit under the battery, and this might be causing
it to grab the battery from the sides. I'm not sure what is causing the
bulging, but it might be that the battery is doing this. It's an old
battery that hasn't worked in a while.

Any suggestions for how to remove it? Would taking the laptop apart
help?

Thanks,

Dan
