This battery is really strange... After an O/N with the battery out of the XO tried to run it down and suddenly none of the info in /sys/devices/0.baterry/power_supply/olpc-battery/ was changing after an hour of CPU burn and the battery was showing as "Full" Shutdown and removing the battery to reset the EC, made it behaved. The battery started from 35% and dropped normally thereafter. As per the suggested test, indeed after shutting down at 9% with the red led on, pressing a game key lights up the red led for ~2 sec. > > What was striking was that the XO-1.75 used 25% of the > battery for 1 run while the XO-1.5 used 65% of the battery! > > If you are going to do more of this then you really need a > better tool > than just the battery SOC measurement.

I can understand some bash scripting but python is out of my league, so please advise. _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
