I wonder whether I'll better do that outside the computer though. After all, the Coulomb counter in the battery does not care much whether it is attached to a computer querying it or not. > You should not stop the discharging prematurely - it affect the > results. I did want to reboot it into normal operation in order to allow the nightly backup to run. I simply ran out of time waiting for the battery to drain completely. Anyway, at a voltage level of < 9.0 V, it wouldn't have lasted for another quarter of an hour. (Worst case cutoff level for a LiIon cell is around 2.7 V.) -- cheers, J"org .-.-. --... ...-- -.. .
