I finally got around to looking up solution to my laptop power problem. I'd actually never really worried about it, since I almost always use the laptop plugged in, but I read a blog post complaining about battery life under Ubuntu, so I figured I'd look into it.

My Dell Inspiron B120 normally got about an hour an ten minutes on battery. I never actually ran Windows on it, so I have no basis for comparison. However, I'd read other comments about people getting two to three times as much battery life on Windows. For instance, my brother's Inspiron 1501 gets about 3 hours.

The good news is that there's "laptop mode." By flipping on the ENABLE_LAPTOP_MODE setting in /etc/defaultacpi-support, I gained about 20 or 30 minutes.

The bad news is that there's not an awful lot of other tweaking to be done. There are some other tips on the Ubuntu wiki, but I haven't found anything that seems to make a dramatic difference. At least, not anything I can configure with a truly intimate knowledge of the system.

So basically, it seems like we're kind of out of luck for the time being. But I'm not going to complain too loud. I'm just glad all the hardware in the laptop actually functions.
