What’s up with my battery? I got this laptop, a Lenovo T400, about a year ago, and my 4 cell battery is reporting 37.4% capacity. This sucks. I’m going to need to get a new one.

What did I do to deserve this? Any fellow Internet users know? I have been running alpha versions of Ubuntu often, has there been some major power management bug that may have killed my battery? Have my usage habits been destructive? I can’t think of any awful abuse that I put my battery through.
