Laptop suspends immediately after wake when ac power was removed before waking up

[Mark]

Binary package hint: gnome-power-manager

This has been reproduced on two Laptops - a Thinkpad T61 and a Dell Mini 1012. The attached debug information (from ubuntu-bug is for the T61), and is reproduced reliably. I am using Ubuntu 9.10 on both machines - desktop edition on the Thinkpad and Netbook Remix on the Dell Mini.

Steps to reproduce:

 * Ensure laptop is awake and AC power is connected
 * Close laptop lid - the laptop suspends as expected
 * Remove AC power while the laptop is suspended
 * Open the lid - laptop wakes up
 * Approximately 5-10 seconds later, the laptop suspends once more

I have attached the output from running 'gnome-power-manager --verbose' manually and performing the above steps on both machines.

I was only able to add one attachment manually, this post has attached the output of running gnome-power-manager --verbose on the Dell Mini.

I too am seeing this behavior on an ASUS Eee PC 900 running Ubuntu 9.10 UNR.

The suspend/wake cycles work as expected when the power source does not change while the unit is suspended.

I see there's a procedure for collecting Gnome-Power-Manager data https://wiki.ubuntu.com/DebuggingGNOMEPowerManager -- but I wonder if only the original bug reporter does this, or would it be helpful for me to add my data to this report.

I have not had this happen in several weeks on my Karmic NBR netbook. I see I am running 2.28.1-0ubuntu1.3 which was apparently updated about six weeks ago. https://launchpad.net/ubuntu/+source/gnome-power-manager -- it says this update fixed the "double suspend" Bug #425411 -- this must be same bug...
