I'll check with Win XP and Linux with latest ACPI CA to see if I notice a speed difference between Windows and Linux. The XP battery indicator detects AC/battery power changes in a few seconds, so I expect the batery status polling in Windows to occur at the same speed. (or does the AC/battery power work with an event? The my assumption won't hold then) Bas. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
