My laptop is Lenovo T400 and OS is Ubuntu 10.10. Here is information about my battery:
$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: charged
present rate: 0 mW
remaining capacity: 28730 mWh
present voltage: 11390 mV
$ cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 56160 mWh
last full capacity: 58730 mWh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 2936 mWh
design capacity low: 200 mWh
cycle count: 0
capacity granularity 1: 1 mWh
capacity granularity 2: 1 mWh
model number: 42T4653
serial number: 285
battery type: LION
OEM info: LGC
$ cat /proc/acpi/battery/BAT0/alarm
alarm: 2936 mWh
- I was wondering if
1-(remaining capacity/design capacity)
is the current charged percentage of the battery? - Since
present rate
is 0 mW, does it mean that the battery is currently not charging nor discharging? - Is the present voltage (11390 mV) being bigger than the design voltage (10800 mV) a bad thing? If yes, what can I do about it? My laptop is currently using power from power cord.
Thanks and regards!
