Power Management Question

Shadowman2oo3 · 11-08-2009, 01:11 PM

Hello fellow Linux Users,

I have a question about power management under Linux. I have a Dell Laptop and I have been able to get suspend and hibernate to work. What I need to know is there a way to get the laptop to hibernate after it is already in S3(suspend) mode? What I mean is say after I close the laptop lid and it goes to sleep can I have it hibernate after say an hour of being in sleep mode. I know Windows does this but can it be done in Linux?

Thanks

Well, that kind of thing can be done (not sure exactly of the once it has gone to S3 part, but couldn't you go directly to hibernate?), but the details of how to do it (and maybe even whether it can be done) depend totally on which GUI you are using.

So, which GUI are you using?

I'm using KDE4. I know I can go directly to Hibernate but sometimes I close the laptop and forget about it. I want it to Hibernate on its own so it doesn't drain the battery and shut off.

I'm not quite able to get to KDE4 right now, but as far as I can remember, setting one of the power profiles like 'extreme powersave' (or the slightly less extreme one, whatever that is called) gives you an automatic switch to 'suspend to ram' which isn't quite what you want. Nice, but it still use some power, even if not that much.

Sorry I am a bit unclear on the details, I'd really need to get back to KDE4 to tell you more.
