same problem here with a TP385. Please check the docu for the TP310 series whether the batteries actually support this information. I.e. my batteries only "know" the critical state (< 10%?), the normal state (>10%, <80%) and the fully charged state (>80%). >> So, this is the question, what can I do to have the kernel check >> (or report, or "be informed bye the bios", or whatever) the battery >> status ?

Hmm, you could start logging the output of /proc/apm over time and together with the average load figure out a formula for the discharge... -tom
