auto hibernate / auto shutdown doesn't work when battery power is critical or the battery is totally empty before

[Fabien Lusseau]

Binary package hint: gnome-power-manager

It is the same problem in all my laptops (a dell inspiron 640m, an ASUS A6K and a Gericom Webgine)

And can you add a system to set the percentage of the battery when it auto shutdown/hibernate the GUI ?

It is a critical bug because it can cause damages to the lithium in the battery when the power is less than 5 % and reduce the battery uptime

Confirmed. I thought it was my imagination but since an update about a week ago (so, around 20th September 2007) gnome-power-manager doesn't hibernate the PC when battery level gets to critical. This had been working fine up to then and was in regular use.

I did a manual hibernate test from a fresh start, and it also fails. Screen goes blank immediately, there's no hard disk activity as you'd expect, and there is no way to interact with the PC (Ctrl+Alt+SysRq+K tried to restart GDM).

There's not much in the log files for the battery-critical event. syslog and daemon.log just show NetworkManager releasing and then re-establishing the network lease, kern.log just shows the restart, auth.log seems to show an hourly cron process at about the same time, but I think that is coincidence. Here's what could be found:

=== auth.log ===

For me Hibernation work manually, but auto hibernate doesn't work at all ...

For your manual hibernate fail, it is an other problem.

[Fabien Lusseau (fabien-beosfrance)]

Please correct this bug before the stable release, it appear in all the laptops computers ... Dell include ...

I've seen this too on a Lenovo Thinkpad T60. On openSUSE 10.3 using KDE3 the laptop shuts down when the battery is critical and the BIOS is sounding an alarm. On Ubuntu Gutsy, the laptop keeps on going until it smashes down as the machine finally runs completely out of power. I've tried the hibernate, shutdown and suspend options and all had the same result - nothing happened.
