Battery status don't work correctly on IBM Thinkpad R30

please attach the output from the files under /proc/acpi/battery
and note if they change between AC/DC.

i'm sorry if my answer come too late.

in /proc/acpi/battery i have one folder BAT0 and inside this folder 3 files:

alarm
info
state

all file are 0 byte size ... what can i do??

thank's very much

What version of Ubuntu is it ?

Can you paste the output of "uname -a" ?

now I'm on Dapper ... it's seem to work on battery-state applet ... it' seem don't work on power-manager applet.

for new version of ubuntu power-manager applet replace battery-state applet?

uname -a:

cff@nb08:~$ uname -a
Linux nb08 2.6.15-18-686 #1 SMP PREEMPT Thu Mar 9 15:29:22 UTC 2006 i686 GNU/Linux

Could you do again what Len proposed ?

So, if I understood correctly, it works normally all the time but when the battery is fully charged. In this case, instead of stop charging the battery and keep using AC it uses the battery only. Is that it ?

Hi, i'm sorry for my delay ... It's correcto what you had write ... now, i'm using dapper and seems to work correctly battery state icon but not power manager icon.

Now, also when battery is full charged battery state show AC cable ... but power manager icon show only battery, like I work out of AC ... it's correct or not?

Thanks for the reply.

Could you have a look into the HAL device manager (Alt+F2, type hal-device-manager). There you have AC Adapter and Battery Bay. Could you tell what are the values of the following in the case where Gnome Power Manager fails to show the AC as present:

- ac_adapter.present
- battery.present
- battery.rechargeable.is_charging
- battery.rechargeable.is_discharging

hi, i have this values:

- ac_adapter.present: true
- battery.present: true
- battery.rechargeable.is_charging: false
- battery.rechargeable.is_discharging: true

thanks!

The results you gave from /proc/acpi/battery and from HAL seem consistent to me. It clearly indicates that once the battery charged your laptop stops using the AC and works on battery. Did you notice anything that can actually confirm this ?

It looks like a hardware bug or a BIOS misconfiguration. We could as well suspect the Linux kernel. Do you have any other operating system you could try on ?

Sorry not to be of great help concerning your issue...

Any news of the bug An3a on Edgy, Feisty or Gutsy?

Hi,

sorry, from november 2006 I don't use IBM Thinkpad, now I work on HP nx7400.

Now it's running Gutsy and it's work fine ... only little different version problem between acpi, acpid and acpi-support package now ... but on a developping version it's usually I think.

;-)
