Title:
Battery design capacity is zero
Status in “linux” package in Ubuntu:
Expired
Bug description:
Seen on Ubuntu 12.10.
I've a Lenovo G780 unit for which the battery design capacity is
reported as zero. This is a brand new unit.
In /sys/class/power_supply/BAT1 I can find the following information:
POWER_SUPPLY_NAME=BAT1
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Unknown
POWER_SUPPLY_CYCLE_COUNT=1491
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=1000
POWER_SUPPLY_VOLTAGE_NOW=11820000
POWER_SUPPLY_POWER_NOW=635500000
POWER_SUPPLY_ENERGY_FULL_DESIGN=0
POWER_SUPPLY_ENERGY_FULL=47520000
POWER_SUPPLY_ENERGY_NOW=36350000
POWER_SUPPLY_MODEL_NAME=
POWER_SUPPLY_MANUFACTURER=Li-Ion
POWER_SUPPLY_SERIAL_NUMBER=PABAS0241231
At first, I thought that this was a battery issue, but when I use
Windows based battery tools, I get good values for the 3 capacity
values:
design capacity
last full charged capacity
current capacity
These 3 values are different in windows, so it's not that one of the
capacity values is reused for one of the other values.
This is a Ubuntu defect.
