For example I use cpufrequency (a daemon to switch CPU frequency on my P4 laptop) http://sourceforge.net/projects/cpufrequency/ (this program checks every some seconds the status of battery) and I use watch -n 8 "cat /proc/acpi/battery/BAT1/*" to see the battery state in a xterm. Is there some lock to access to status of battery? thanks for your time, Paolo Dovera
