Public bug reported:
Binary package hint: gnome-applets
Hello,
There is a bit of a problem with the battery applet. I am using Feisty
with all the updates, and a Lenovo V100 laptop.
The problem is especially there at the beginning. After a while, things get
better. However, it takes a little too long.
This is a table of what the monitor tells me. At this point, the machine had
been running for about 15 minutes (and the "battery left" was just silly to
start with, but that's OK).
Here we go:
Time - Battery left
5:20PM - 1.54
5:21PM - 1.48
5:25PM - 1.35
5:30PM - 1.28
5:40PM - 1.15
5:45PM - 1.09
5:50PM - 1.04
5:55PM - 1.00
6.00PM - 0.56
6.05PM - 0.50
As you can see, it only starts telling the truth after about 35 minutes
(that's 15 minutes before I started logging, plus 20 minutes after
starting logging).
The computer was used the same way throughout these measurements: light
internet browsing, etc. The fan turned itself on every now and again
throughout the testing. PLEASE NOTE that I am in Australia, it's summer
and it's bloody hot here.
This is the output of cat /proc/acpi/battery/BAT0/*

The output of lshal is attached.
I know I might be knit picking, but really, 40 minutes to have a realistic
estimate really is a little bit much.
I hope this helps. I am here if you need me to test it more - I am more
than willing to keep track of what the estimates are every 10 minutes.
Bye!
Merc.
