AC disconnect not seen by Battery Charge Monitor on Travelmate 3000

[Tero Karvinen]

Battery Charge Monitor 2.13.90 always shows "Connected to AC power", even if AC is disconnected and computer is running on battery. Battery load level is shown correctly.

Gnome power manager applet shows AC connection status correctly in tooltip. User just has to make power manager applet visible with 'gnome-power-preferences'.

I am using Acer Travelmate 3000 (3004WTMi) and Dapper Flight 3 with updates on 2006-03-02.

Ryan: do you have any idea on this?

[Allison Karlitskaya (desrt)]

No idea.

Tero: if you could run 'lshal' and include the relevent sections (ie: the parts to do with your battery) in this bug report it would be appreciated. Please do this when on battery power (ie: when the applet is showing the wrong information).

Cheers

It works now, but after a considerable (20 s - 30 s) delay. In the morning, the AC icon did not work at all but was always on. I don't know why the behaviour has changed for the better, I have tested lot of configurations today.

I am attaching an lshal taken during the delay (after disconnecting AC, before AC sign has been hidden in battery meter).

  battery.rechargeable.is_discharging = false (bool)

Your battery is initially reported as not discharging. battstat takes this to mean "I'm on AC".

I think maybe the laptop is failing to delivery "battery state change" ACPI events to hald which means that hald is only updating the battery when it polls acpi (explains the 30 seconds delay). Only when it does the poll would it properly update the battery state.

This should be easy to fix.

[Allison Karlitskaya (desrt)]

er. I mean, should be easy to work-around in battstat. The fix involves getting your laptop to properly deliver the events, which is probably out of our hands.

Works in 6.06 Dapper with normal updates.

I'm the original reporter and there has not been activity for a while. Thus, I close the bug.
