GNOME Bugzilla – Bug 505243
Laptop does not hibernate when power is critically low
Last modified: 2008-02-17 09:58:17 UTC
Please describe the problem: This bug was originally reported at Red Hat bugzilla #351551. Basically, the issue is that although g-p-m does display a warning about power being critically low, it does not put the laptop in ACPI S4 mode. Steps to reproduce: 1. Get a Toshiba Satellite A100-847 laptop 2. Plug out the AC cord 3. Wait until battery runs out of power Actual results: Laptop goes off Expected results: Laptop hibernates Does this happen every time? Yes Other information:
Created attachment 101507 [details] Power chart Take a look at the end. There is a false lid closed event, and also the power goes up without reason. FWIW, g-p-m 2.18 from Fedora 7 was working perfectly OK.
It looks like your battery is pretty screwed - could you please attach the discharge accuracy and data graph screenshot and we can see if this is indeed the case. Thanks.

I'm not sure what do you mean by a screwed battery, but I think this is unlikely. This laptop is only 11 months old. What is more, when g-p-m says that the battery is almost empty, it is almost empty. The time estimate for fully loaded battery seems a bit off, though (95 mins), as under windows (never really measured linux) you can certainly pull more than that.
Hmm. You are correct, the battery is fine. Could you please run gnome-power-bugreport.sh and attach the output here. Thanks.

Hmm, can I provide some more info?
Hibernation has started to work again. That's strange. Maybe that was a kernel bug and one of the kernel updates has fixed it? Or maybe g-p-m eventually learned when to hibernate? If that's the case, the required time is was far too long. Anyway, the problem seems to be gone now (without any g-p-m updates), so I'm closing the bug.
