Hi ,I have a Studio 1555 laptop ,when I install "quickset" from dell drivers in windows7, I have a battery meter program that helps me a lot, I can control my battery charge anytime, without unplugging the battery over and over, I want to know if there is a linux version of this usefull tool, anyone can help? if there isn't such version, so how can I control my battery charge(control "Charging" and "Not Charging" states on my own)? how this "Dell Battery Meter" tool works? deals with BIOS or Battery's Internal Circuits? (I have my orginal 9cell Lion battery by the way...)
