How to get the correct battery status?
- by GUI Junkie
At this moment, ever since I installed Ubuntu on this machine, the battery status says: not present.
Looking at this answer, however, I find that /proc/acpi/battery/BAT1/info (sometimes its /proc/acpi/battery/BAT0/info, use tab complete to help) has the following info:
present: yes
design capacity: 4400 mAh
last full capacity: 4400 mAh
battery technology: rechargeable
design voltage: 11100 mV
design capacity warning: 300 mAh
design capacity low: 132 mAh
cycle count: 0
capacity granularity 1: 32 mAh
capacity granularity 2: 32 mAh
model number: BAT1
serial number: 11
battery type: 11
OEM info: 11
In accordance to this answer, I've checked the /proc/acpi/battery/BAT1/state file:
present: yes
capacity state: ok
charging state: charged
present rate: unknown
remaining capacity: unknown
present voltage: 10000 mV
The acpi -b command returns:
Battery 0: Unknown, 0%, rate information unavailable
Any suggestions on getting the battery info updated?
