hibernation

Hey all,

I have the hibernation option disabled on my laptop (Dell XPS 12), and I've also disabled the rapid start technology that uses hibernation. Even when turning those features off, I noticed there was still an 8 GB hibernation file sitting on my hard drive; upon doing some research, I discovered typing "powercfg -h off" on the command prompt would ensure that file was removed, and it did indeed work.

So I thought everything was fine except the other day I left the laptop running while on battery, playing music. Even though in the power settings it is set to hibernate the laptop when the battery gets low (critical battery action is set to "hibernate," and critical battery level says 5%) it did not--it actually ran the battery until it died, without hibernating. Is this expected behaviour when hibernation is turned completely off? I had assumed even with hibernation disabled, it would still resort to that when the battery reached critical level.


Thanks.

Hello. "powercfg.exe -h off" deletes the file hiberfil.sys
Usually when hibernation is disabled systems default to shut down.
Have you rechecked your power options since disabling hibernation?
When disabled, options to hibernate are removed. If disabled, the system will not create hiberfil.sys

You can run "powercfg.exe -h on" to re-enable hibernation.
Is there an option to shut down when the battery gets low?

Why would you think it would hibernate when you have hibernate turned off?

Hey,

Thanks for your reply. I watched it, and it would wait for the battery to drop to 0%, and then look like it was shutting down (the screen would go black), but then it would return to the login screen, and wait for the battery to completely die. It didn't shut down properly.

I figured it out: under "critical battery action" in the power options advanced settings, it said "Hibernate" under "on battery," but when clicking on that option, Sleep or Shut down were the only options I could actually choose. So, it had an invalid setting since hibernate was not available and yet somehow still set.

I only disabled the hibernate setting b/c I don't want an 8GB file perpetually present on the HD; it would be nice if I could keep the hibernate setting and it would purge that file after using it, but that has not been my experience. Oh well.
