No AE_* ACPI errors and battery initialisation looks good, assuming you have just one battery fitted of the two supported. It's quite possible that there's no problem. Li-Ion batteries are not trickle-charged like older technology batteries (NiCd or NiMH) but after a full charge gradually self-discharge over days, perhaps weeks while the laptop is powered, until the battery gets down to below around 95% (on my Thinkpads anyway), when it will get boosted back to 100% again. My X200 is down to 95%; I'm expecting a charge cycle any day now :) State: high Remaining capacity: 95% Remaining time: unknown Present rate: 0 mW Present voltage: 12418 mV Try unplugging power and watching with acpiconf -i0 until down to say 90% or lower, then reconnect power; it should charge up to 100% again, and stay up around 98-99% for a while before gradually dropping. If it doesn't, try reporting the result of acpiconf -i0 at different states and times; just the lines above will do, except for the first. And don't forget to let it run on battery sometimes, it's good for it; occasional deep (or even complete) discharges help keep the battery's internal 'coulomb counter' in good shape, and don't hurt battery life. cheers, Ian
