Hello,
battery in my X61s is not charging while power supply is connected. From the OS point it looks as below:
# 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

I've checked battery port with multimeter and it seems that voltage is not given to it. So looks rather like HW issue. Is it something that could be easily fixed?

Judging by the number of values =0, I'd say your battery is utterly dead.
Try another one.

For reference, here's the output from a functioning battery:

POWER_SUPPLY_NAME=BAT0
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=0
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=14400000
POWER_SUPPLY_VOLTAGE_NOW=16326000
POWER_SUPPLY_POWER_NOW=3934000
POWER_SUPPLY_ENERGY_FULL_DESIGN=74880000
POWER_SUPPLY_ENERGY_FULL=74880000
POWER_SUPPLY_ENERGY_NOW=73310000
POWER_SUPPLY_CAPACITY=97
POWER_SUPPLY_CAPACITY_LEVEL=Normal
POWER_SUPPLY_MODEL_NAME=42T4776
POWER_SUPPLY_MANUFACTURER=SONY
POWER_SUPPLY_SERIAL_NUMBER= 718

Two things to check - the power jack and the power supply.

Hello,
thanks for your answers. Battery is dead because it's not being charged. It worked fine before. Moreover I've checked with two power supplies and the situation is the same. Works ok when power supply is connected, after disconnecting server is powered off.

The system needs to be tested with another *known working* battery, that's the only way to find out whether the battery is dead or the charging circuit got blown without ripping the entire system apart.

Good luck.
