Laptop suspends when power unplugged

Daniel, I've seen this myself a couple of times. Any ideas?

It happens randomly on my Sony Vaio SZ as well.

Please note that if I unplug the power when my laptop lid is closed, the laptop goes to suspend mode. This is in my opinion the proper behavior.
The fact that the same behavior occurs randomly when the laptop lid is open could lead us to think that the lid state may not be reported properly by the kernel (or whatever is supposed to report this :-P). That's probably why the laptop goes into suspend mode, thinking that the lid is closed when it's actually not.

Hope it helps.

lenovo 3000 n100 laptop with dapper flight 6 + updates. the battery is fully charged and the cord is plugged in. when i unplug the power cordinstead of dimming the display the laptop goes to suspend. The laptop very consistent with this behavior.

Apparently this is fixed in g-p-m 2.14.3 see http://mail.gnome.org/archives/gnome-power-manager-list/2006-April/msg00092.html and http://mail.gnome.org/archives/gnome-power-manager-list/2006-April/msg00091.html

I get this on my IBM x31 too.

Is it too late to get this into dapper?

Richard, do you have the HAL and g-p-m fixes as separate patches so that can be backported easily?

gnome-power-manager (2.14.3-0ubuntu2) dapper; urgency=low

  * Patches added in this version:
    - 20-enable-xfce-startup.patch
      Enable XFCE in the .desktop file so that it starts up for xubuntu too.
      Closes: launchpad #43077
    - 30-transparent-notification-icon.patch
      Enable the eggtrayicon stuff to do transparency.
      Closes: launchpad #40446
    - 95-lid-state-tracking.patch
      Augment lid state tracking to use hal if hal reports it is capable
      of tracking the lid state.
      If hal reports an acpi_LID with button.has_state == true then we use
      that state information whenever we want to consider the lid switch
      This should deal with LP #33072 and thus its duplicates #42988,
      #42823, #40730, #40662, #37442, #36459 and #33952
    - 96-disable-session-save-on-shutdown.patch
      Disable the saving of the session during critical power shutdown.
      This confuses too many people for now.
      Closes: launchpad #35691
  * Patches changed in this version:
    - 40-ubuntu-schema-defaults.patch
      Alter screen lock defaults to always lock, regardless of screensaver.
      Closes: launchpad #39448
  * Related fixes: #35591 -- We believe this is caused by the hal and
    gnome-power-manager interaction wrt. lid status. The new hal and the
    2.14.3 gnome-power-manager should fix it all.
