Bug#574850: dup of #571161

[M Z]

Hi Michael,


checked out that bug thread and here are my numbers (cat
/sys/class/power_supply/BAT1/uevent && acpi)

a) power cord plugged in and full battery.
POWER_SUPPLY_NAME=BAT1
POWER_SUPPLY_TYPE=Battery
POWER_SUPPLY_STATUS=Full
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Unknown
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=11100000
POWER_SUPPLY_VOLTAGE_NOW=12552000
POWER_SUPPLY_CURRENT_NOW=0
POWER_SUPPLY_CHARGE_FULL_DESIGN=4400000
POWER_SUPPLY_CHARGE_FULL=4166000
POWER_SUPPLY_CHARGE_NOW=4166000
POWER_SUPPLY_MODEL_NAME=MS-1221
POWER_SUPPLY_MANUFACTURER=MSI Corp.
POWER_SUPPLY_SERIAL_NUMBER=
Battery 0: Full, 100%

b)power cord plugged off just milliseconds before, the battery still
fully charged (4m wrong time remaining shown in warning pop-up
notification - in case of battery charged bellow ~ 20% it would try to
shutdown the laptop)
POWER_SUPPLY_NAME=BAT1
POWER_SUPPLY_TYPE=Battery
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Unknown
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=11100000
POWER_SUPPLY_VOLTAGE_NOW=12328000
POWER_SUPPLY_CURRENT_NOW=65535000
POWER_SUPPLY_CHARGE_FULL_DESIGN=4400000
POWER_SUPPLY_CHARGE_FULL=4166000
POWER_SUPPLY_CHARGE_NOW=4096000
POWER_SUPPLY_MODEL_NAME=MS-1221
POWER_SUPPLY_MANUFACTURER=MSI Corp.
POWER_SUPPLY_SERIAL_NUMBER=
Battery 0: Discharging, 98%, 00:03:45 remaining

c)power cord still unplugged, battery still fully charged, time like
second or two after the power cord yanking (everything seems to be ok
now)
APOWER_SUPPLY_NAME=BAT1
POWER_SUPPLY_TYPE=Battery
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Unknown
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=11100000
POWER_SUPPLY_VOLTAGE_NOW=12295000
POWER_SUPPLY_CURRENT_NOW=1536000
POWER_SUPPLY_CHARGE_FULL_DESIGN=4400000
POWER_SUPPLY_CHARGE_FULL=4166000
POWER_SUPPLY_CHARGE_NOW=4096000
POWER_SUPPLY_MODEL_NAME=MS-1221
POWER_SUPPLY_MANUFACTURER=MSI Corp.
POWER_SUPPLY_SERIAL_NUMBER=
Battery 0: Discharging, 98%, 02:40:00 remaining


So it seems like the POWER_SUPPLY_CURRENT_NOW=65535000 right after
yanking out the cable leads to the wrong estimations of remaining
battery life and premature shutdowns/hibernations/suspends in case of
weaker battery energy levels.


Thanks for your time. :)
