Description Cameron Meadors 2008-03-26 14:53:07 UTC

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):

kernel-2.6.18-84.el5
gnome-power-manager-2.16.0-9.el5

How reproducible:

Every time

Steps to Reproduce:
1. Use gnome-power-manager menu or Fn-F4 to suspend.
2. Plug the laptop into the docking station
3. 

Actual results:

Laptop changes to a state of not suspended but plugged in to AC and charging battery

Expected results:

I am able to resume from suspend with it docked.

Additional info:

I would be happy to supply logs, but with the sudden power off, I doubt there
are any.

Does booting with "acpi_sleep=s3_bios" as a boot arg help any?

Comment 2 Cameron Meadors 2008-03-26 17:34:54 UTC

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.

Hi,
the RHEL5.2 release notes will be dropped to translation on April 15, 2008, at
which point no further additions or revisions will be entertained.

a mockup of the RHEL5.2 release notes can be viewed at the following link:
http://intranet.corp.redhat.com/ic/intranet/RHEL5u2relnotesmockup.html

please use the aforementioned link to verify if your bugzilla is already in the
release notes (if it needs to be). each item in the release notes contains a
link to its original bug; as such, you can search through the release notes by
bug number.

Cheers,
Don

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.

Comment 7 Brian Maly 2008-04-03 16:38:47 UTC

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.
