Hi!
A couple days ago, I updated my test build to commit
8033c6e9736c29cce5f0d0abbca9a44dffb20c39 and noticed an odd behavior
with the battery. If I unplug the power, the battery discharges and
that is reflected in /proc/acpi/battery/BAT0/state. I am not certain
the discharge is continuous and uniform or if it goes in steps. When I
plug the power back in, the level stays at a constant value (+-1mAh)
for a considerable period of time. It then does a single step back to
the fully charged value.
I have not done any searching to see when this began. I had been running
the ubuntu 2.6.22-14 kernel before this and the behavior was normal.
I am not certain what information you will need. Commit is above.
git bisect would certainly help...
$ cat /proc/acpi/battery/BAT0/alarm
alarm: unsupported
$ cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 4800 mAh
last full capacity: 4096 mAh
battery technology: non-rechargeable
Because something is clearly wrong here.
Pavel
