Try ibam, and (if you use gkrellm) gkrellm-ibam. I've been using them on my laptop for a month or so now, and they seem like roughly what you're looking for. If you don't use the krell, you may need to read the documentation in some detail and do manual configuration to get it checking your battery state on a regular basis (and thus building a meaningful usage/charge profile), but I believe it's doable. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
