I recently installed Linux Mint 13 with Xfce on an Acer Aspire One (532h) and I've been really pleased with it apart from one issue...the battery status indicator. Basically, if I select the "always show icon" option, the icon appears in the panel but says the adaptor is online, even though it isn't. If I select any other option it doesn't normally appear at all. At one point it was appearing when I selected the "when battery is charging or discharging" option but now it doesn't do that either.
I searched this site and read through quite a few threads but couldn't see a solution to my problem. I tried the following commands in the terminal:
cat /proc/acpi/battery/BAT0/info &&
and I get the following output:
design capacity: 4400 mAh
last full capacity: 2942 mAh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 220 mAh
design capacity low: 132 mAh
cycle count: 0
capacity granularity 1: 264 mAh
capacity granularity 2: 3780 mAh
model number: UM09H31
battery type: Lion
OEM info: SANYO
cat: /proc/acpi/battery/BAT0/status: No such file or directory
I'm a bit confused about that last line because it comes up with all the info and then says "no such file or directory", but I'm new to Linux so maybe I just don't understand what's going on.
At first, when I used those commands the battery indicator would suddenly appear in the panel and show the correct state of the battery rather than telling me the adaptor was online but now it doesn't appear any more. I've tried a number of alternative battery monitor applications and most of them don't appear anywhere when I run them. One that I tried, xbattbar, appears and tells me my battery is -1% all the time and the last time I started it, the Xfce Power Manager icon appeared in the panel as well, showing the correct info.
Sorry for the lengthy post, I wanted to make sure I supplied all the relevant info. I'd really like to solve this problem because an OS with no battery indicator on a netbook is not very useful and I'd like to carry on using Linux Mint.
Thanks in advance for any help that anybody can give me.
