nah, tried that when I had windows on it. that and a bunch of other stuff from the unhelpfulest site on the webz - dell.com. screen rates and resolutions and auto brightness as well. the battery contacts are way too tiny for me to do anything meaningful there. besides, I’m thinking that if the battery is the problem, then there shouldn’t be any issues when running the thing on external power; it’s not like the battery is powering the laptop when connected to external power, it’s running on external power and using the surplus to charge the battery.
