Red Hat Bugzilla – Bug 439006
T60 powers off when suspended and plugged into dock
Last modified: 2010-03-14 17:32:21 EDT
Description of problem:
If my T60 is suspended (suspend-to-ram), it powers off completely when I plug it
into my docking station. I then have to turn it on with the power button. When
I log in I get a dialog saying the resume failed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use gnome-power-manager menu or Fn-F4 to suspend.
2. Plug the laptop into the docking station
Laptop changes to a state of not suspended but plugged in to AC and charging battery
I am able to resume from suspend with it docked.
I would be happy to supply logs, but with the sudden power off, I doubt there
Does booting with "acpi_sleep=s3_bios" as a boot arg help any?
acpi_sleep=s3_bios does help. I cycled suspend and resume in and out of the
dock a 6 or 7 times and only once did it power off when I docked it. That was
in a different dock. I will test more.

I also see the same issue when I dock the laptop when running (not suspended).
Is that a corrallary of this bug or a different bug? The annoying thing is that
it is not every time, but more that half the time that laptop powers off.
Its the same bug if the workaround in Comment #1 solves the problem. If not its
a seperate bug and a bugzilla should be opened for that issue as well.
