Power management on a laptop

Was sitting in a mall today, wondering why my PC powers down so fast. Tried using powertop, it gave a lot of tips on-the-fly.

One thing useful I’ve been reminded of by it: the mouse (touchpad in this case) causes a lot of interrupts, like 50/s or so. So I try to avoid using it. Luckily, I’m a keyboard+terminal fan anyway.
