I have been using Ubuntu 11.04 on DELL Inspiron 14R (N5010) laptop for last three months. Before I switch to Ubuntu my laptop battery used to give 2.5 hrs to 3 hrs back-up. But since I have been using Ubuntu, it has been reduced to 1hr to 1.5 hrs at max.
I tried following commands:
cat /proc/acpi/battery/BAT0/state
Which gave result as:
present: yes
capacity state: ok
charging state: charged
present rate: 1 mA
remaining capacity: 4400 mAh
present voltage: 12407 mV
Then I tried acpi -b
, that resulted in:
Battery 0: Unknown, 100%
When I gave command as upower -i /org/freedesktop/UPower/devices/battery_BAT0
native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0

- Someone please let me know, what is going wrong with my laptop?
- How can I get charging with full capacity?
Kindly go through the ACPI Problem and regression problem occured during the period from the ubuntu 10.10, 11.04 and 11.10.. Try to install the ubuntu 12.04 or the newer version . Or else check with the installing the Jupiter app. which is mainly developed eee asus .
