I thought the normal behavior for a laptop when the battery runs down and close to running out is to warn the user with a dialog saying the battery is low, and the computer will go to sleep in x minutes. It'd then go into deep sleep until you plug it back into the socket, or until the battery runs completely dry. But with my MBP, there was no warning or going to sleep. The battery runs out, and BAM the computer's turned off completely, just like that. I had this happen a few times, and know this couldn't be good for the hardware at all. So what's up with that? Leopard issue? Hardware issue? What?
