unplugging AC puts laptop to sleep

[Matt Price]

Binary package hint: acpi-support

Unreliably, my dell d820 will go immediately to sleep when i unplug it from ac power. This is on an up-to-date gutsy, but it resembles the behaviour described in this inactive bug:
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/44863

 In general it happens unexpectedly; recovery of information has been impeded by unreliabe resume from suspend caused probably by compiz/nvidia combination. If there's anything I can do to help track down the problem (I could runa script in the background or something) please let me know.

Why don't you try to disable desktop effects and do in a terminal:

lshal -m to try to recover the information

[Matt Price (matt-price)]

thanks rafael. i will try to remember to keep that running all the
time; and when this event recurs, i will hopefully have the info.

more when i can reproduce the effect.

sorry for the delay. finally caught this bug properly, here is the
output of hslal -m, which doesn't say much to me, with the possible
exception of :computer _logicaldev_input_0 removed:

all of this stuff comes *before* the shutdown is ocmplete. after
wakeup, there are no immediate events reported.

i hope this helps a little, and would be of course happy to...

Hello,
I am also experiencing something similar. I use uswsusp to suspend and hibernate, and upgraded from feisty to gutsy. Unplugging the laptop from AC power causes it go into suspend.

[Matt Price (matt-price)]

[ping] -- just wondering if anyone's paying any attention to this
anymore, and whether the other reporters are still having issues. For a
couple of months this problem was intermittent for me, but in the last 6
weeks or so it's been omnipresent again. I suspend so often now that
I've discovered a suspend b ug, too -- about 2-5% of the time resume
fails and the system locks -- so this bug has become a little more
intrusive. i'd love to help track it down if there's anything i can do
beyond the reports i've already given. thanks,

matt

Hello.

I just upgraded to 8.04 and am newly experiencing this.

It occurs about 70% of the time. As you can imagine, that's really annoying, and I fear it needlessly wastes power and time when it goes to sleep, only to be reawoken moments later.

This did not occur with 7.10 or previous releases.

My system is a Acer Travelmate C100 Tablet PC.

[Richard Schwarting (aquarichy)]

Hello.

So I spent some time trying to get a good log of "lshal -m". My workflow usually sees me keeping my laptop on for a while and changing between hibernating and suspending. Anyway, my steps to reproduce this are:

Steps:
1. boot up
2. manually hibernate, wake-up
3. remove AC Adapter

Actual Results:
* laptop enters suspend (!)

Expected Results:
* laptop does not enter suspend :)

The laptop behaves properly on AC Adapter removal up until my first hibernate. I have annotated the output of "lshal -m" to provide a better idea of what I was doing throughout.

Notably, I see the following the first time I hibernate:
18:36:42.026: computer_logicaldev_input_2 property button.state.value = true
18:36:42.061: computer_logicaldev_input_2 condition ButtonPressed = lid
I do not, however, see this during subsequent hibernations.

Perhaps when I awake from hibernation, button.state.value should equal false? or ButtonPressed should change?

I checked computer_logicaldev_input_2 under "lshal -l" and got the following (left-angle brackets added to note the attributes previously mentioned):

udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_2'
  button.has_state = true (bool)
  button.state.value = true (bool) <<<<<<<<<<<
  button.type = 'lid' (string) <<<<<<<<<<<
  info.addons.singleton = {'hald-addon-input'} (string list)
  info.capabilities = {'input', 'input.switch', 'button'} (string list)
  info.category = 'input' (string)
  info.parent = '/org/freedesktop/Hal/devices/computer' (string)
  info.product = 'Lid Switch' (string)
  info.udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_2' (string)
  input.device = '/dev/input/event5' (string)
  input.product = 'Lid Switch' (string)
  linux.device_file = '/dev/input/event5' (string)
  linux.hotplug_type = 2 (0x2) (int)
  linux.subsystem = 'input' (string)
  linux.sysfs_path = '/sys/devices/virtual/input/input5/event5' (string)

Help :)

I can confirm this problem.
And I'm sure this would only occur after suspend and wakeup.

Is this symptom still reproducible in 8.10?

Seemingly not.

Thanks for the feedback; marking as resolved.
