Hello,
I'm running a Lenovo T400 thinkpad, the battery is from 2010, and the
battery cycle count (as reported through the tp_smapi module) is 331
cycles. So the battery is in reasonable condition, and the thinkpad itself
is in good condition in all but caring the battery.
I do not know why, but despite buing plugged in, while the computer is on
or off, the battry stays at 0$ charge. I cat
/sys/devices/platform/smapi/BAT0/state and get "idle" back.
Searching the archives (at least the ones since I've been subscribed) and
google didn't turn up any information I can use to determine why my battery
is so stubbornly not charging.
Yes, the battery is at 0%. I can unplug the laptop and watch the machine
instantly poweroff.
Dump of /sys/devices/platform/smapi/BAT0 follows.
Any help would be much appreciated,
