Battery isn't charging [Lenovo X61s]

Hello,
my battery is not charging while power supply is connected. Do you know how could I determine if it's battery or driver problem? This is what I get from /sys/class:

# cat /sys/class/power_supply/BAT0/uevent
POWER_SUPPLY_NAME=BAT0
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=0
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=14400000
POWER_SUPPLY_VOLTAGE_NOW=12579000
POWER_SUPPLY_POWER_NOW=0
POWER_SUPPLY_ENERGY_FULL_DESIGN=63360000
POWER_SUPPLY_ENERGY_FULL=54840000
POWER_SUPPLY_ENERGY_NOW=0
POWER_SUPPLY_CAPACITY=0
POWER_SUPPLY_CAPACITY_LEVEL=Critical
POWER_SUPPLY_MODEL_NAME=92P1173
POWER_SUPPLY_MANUFACTURER=SANYO
POWER_SUPPLY_SERIAL_NUMBER= 1714

Many thanks,
PM

You might want to update your bios/firmware. For my thinkpad lenovo has released a firmware update solving a rather nasty bug regarding the battery, which they don't consider very important funnily enough.

In my case the changelog said:

[Important updates]
Nothing.

[New functions or enhancements]
Nothing.

[Problem fixes]
- Fix the issue that battery over discharge and then cannot charge.

Hello,
I've checked it with multimeter and it seems that battery is fine but the problem is with socket on laptop side. I need to check now if this can be fixed somehow...:) thanks for help

Do you have the tp_smapi package/kernel modules installed? Maybe you set the thresholds in a specific way which would prevent the battery from being charged when your power supply is plugged in.
