Dell Inpsiron attempts hibernation when power cord is plugged in

[Adam]

Binary package hint: devicekit-power

Summary: I am on a Dell Inspiron 1501, several years old. Whenever I plug in the power adapter after running on battery, I get a message to the effect:

"Battery is critically low. System is about to hibernate."

The computer then begins the hibernation process but doesn't make it; the screen goes black but the system doesn't shut down. The only way to fix it is to hold down the power button till the system hard reboots.

This bug is identical in every way to https://bugs.launchpad.net/ubuntu/+source/devicekit-power/+bug/481056 except that the user who reported that bug had a Dell Vostro 1000, whereas I have a Dell Inspiron 1501. Users at the linked bug page were directed to file separate bug reports if the were using other systems.

I have the same problem. (dell inspiron 1501 -- ubuntu 9.10)
I've read the other bug report as well, but I didn't see any answers.
Have you happened to find anything useful so far?
Anyway I am making a seperate bug report (I have a different CPU, than you.) as well. Might come someone to help.

I am also experiencing a similar issue on a MSI Wind U100 running Ubuntu Lucid 10.04:
Except for me it happens whenever i plug out the power cord! Very nasty and annoying bug!!

[Alexey Brodkin (alexey-brodkin)]

The same issue as dfme mentioned above. I have MSI Wind U90 with up to date Ubuntu Lucid 10.04.
Netbook has fully charged battery, then I unplug DC connector and within 1 minute (not immediately) netbook falls into hibernate.
After waking it up with power button netbook operates from battery power normally, showing 100% battery icon in tray.

I also have an MSI Wind U100. I'm seeing the same behavior when unplugging. Clicking on the battery icon in the system tray to check the status shows the proper battery life. Doing this prior to hibernating appears to prevent the hibernation.

I have this same forced hibernation on power cord disconnect with Medion Akoya E1210. This machine is a rebadged MSI Wind U100. This bug only manifested since upgrade to 10.04 Lucid Lynx.

[Carl Heymann (ch-heymann)]

It's been happening to me as well, on an MSI Wind U100 Plus, only since installing lucid. Didn't happen on Jaunty.

[Mathieu Marquer (slasher-fun)]

People encountering the bug with a MSI Wind under Ubuntu 10.04 should open a separate bug report, since hardware and ubuntu version is different.

[Alexey Brodkin (alexey-brodkin)]

Mathieu, could you please clarify which details, logs and so on would be helpful for MSI Wind netbook bug report?
Thanks

To those who has PLUG OUT problems turn off time_policy. Here is details:

[Wesley Werner (wesley-werner)]

On a MSI U100 with this issue, a temporary but less annoying work-around is to run gnome-power-preferences, and on the "On Battery" tab, change the critically low option from Hibernate to Suspend, so you can resume after switching power on/off.

Thanks Konstantin for the time_policy fix, I'll try it out tonight.
