|
| hi fellas! wanted to check with you guys. I got lenovo edge 330, and interesting question regarding acpi showing up battery percentage: after 2 or more days of uptime the percentage goes from 100% -->> 99% and state becames like this: "Battery 0: Unknown, 99%". I wonder if this is normal or maybe I could have forgot some modules to compile? Thanks |

On my old lenovo v570 (onboard was Debian testing) I got the same issue. Sometimes perc. was even lower than 99%. Sometime after reboot the acpi state came back to normal, like:
| Code: | gentoo boot # acpi
Battery 0: Full, 100%
gentoo boot #

| Not really sure, but could that be the cause if I compiled acpi modules directly into kernel? (on my lenovo e330 -- Gentoo) |

Batteries loose maximum capacity with time, though I wouldn't expect the effect
to show over a couple of days. To know exactly what is going on check the
/sys/power (???) entries directly. They will give you current charge, maximum
charge, and maximum design charge and lots of other stuff.
