Time To Die
What's the lifespan of a notebook battery these days?
I got my notebook last September, and at the time I could watch 3 hours of anime on a battery charge. I was editing the subtitles for Dirty Pair episode 4 on my way home yesterday, and the battery was dead by the time I got to Waitara; that's about 40 minutes. And that's less intensive than just watching anime, because I keep pausing the video while I edit the script.
Also, the power meter went from 10% to 3% in two seconds, which seems to be just a tiny bit abrupt.
I'm doing a test right now: 100% CPU, screen on, no disk activity; so far it's gone from 98% (which is where it is once you've booted from standby on battery) to 57% in 14 minutes. The 3% per minute seems to be pretty steady. Also crappy. Particularly since the last 10% is basically gone anyway.

That sounds a bit abrupt.
The only thing I've heard for that is to charge the battery again from full discharge - which it seems you'll have to do anyway - but 40 minutes sounds like it is gone for good.

I warned you running your waffle iron from a USB port was a bad idea.
