I think I know why the battery monitor doesn't work.
For comparison my netbook:
Code:
$ cat /sys/class/power_supply/BAT0/uevent 
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=8400000
POWER_SUPPLY_VOLTAGE_NOW=7500000
POWER_SUPPLY_CURRENT_NOW=1192000
POWER_SUPPLY_CHARGE_FULL_DESIGN=6580000
POWER_SUPPLY_CHARGE_FULL=4194000
POWER_SUPPLY_CHARGE_NOW=3337000
POWER_SUPPLY_CAPACITY=79
POWER_SUPPLY_CAPACITY_LEVEL=Normal
POWER_SUPPLY_MODEL_NAME=901
POWER_SUPPLY_MANUFACTURER=ASUS
POWER_SUPPLY_SERIAL_NUMBER=
Notice the key POWER_SUPPLY_CHARGE_NOW which is used to determine the current charge of the battery:
Code:
$ cat /sys/class/power_supply/BAT0/charge_now 
3237000
On the N900 (on battery) I get this:
Code:
$ cat /sys/class/power_supply/bq27200-0/uevent 
POWER_SUPPLY_NAME=bq27200-0
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_VOLTAGE_NOW=4012000
POWER_SUPPLY_CURRENT_NOW=307912
POWER_SUPPLY_CAPACITY_LEVEL=Normal
POWER_SUPPLY_TEMP=311
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CHARGE_FULL_DESIGN=2056320
POWER_SUPPLY_CYCLE_COUNT=22
POWER_SUPPLY_POWER_AVG=315818
POWER_SUPPLY_CHARGE_NOW is missing so the battery monitor has no way to determine the current charge of the battery:
Code:
$ cat /sys/class/power_supply/bq27200-0/charge_now
cat: /sys/class/power_supply/bq27200-0/charge_now: Keine Daten verfügbar
("No data available")
