By unplugging the battery and booting up with the AC cord only, I can get into my OS (Linux) but then after ~10 minutes it suddenly shuts down - the weird thing is it doesn't shut down abruptly, like when you hold down the power button, but it shuts down like I initiate it from inside the OS. Doing the 30-second power button trick doesn't seem to help.
What's going on with my machine?
