Suspend Question

jsteel · 02-23-2010, 03:51 PM

Hi,

I recently found out the difference between an S1 and an S3 suspend. One of my laptops seems to just be doing an S1 suspend but I would prefer an S3 suspend. How can I do this?

I believe it is doing an S1 suspend as it's my only laptop that will wake by pressing a key. My other laptops wake only by the power button. It is also quicker to enter suspend and resume so it's not doing the proper deep sleep to RAM.

Thanks

The settings for suspend options are in the bios.

When you first boot up you will see a key designated to press to enter setup.

Within the setup there will be hardware or power options and suspend is usually there.

Good luck
Bob

Thanks, I've checked out the settings in my BIOS but there's nothing to do with power options. I only have general, security, boot and exit; very minimal! Nothing to do with power.

I am using Gentoo and there is a script called "hibernate-ram" for S3 sleep. My computer wakes up when I press power button. I do not know how that script works but I think it is a client for acpid. May be there exists a similar script for your distribution.

I don't know if it works or not, but there is a web page I found about hibernating on debian

Thanks for your suggestions. I'm still not any further along with this I'm afraid. It's very annoying as it resumes when my laptop lid slightly opens on the move (there's no catch). I must then unlock my session before I can suspend it again. On my laptop that does an S3 suspend, I must manually push the power button for it to wake up; this is ideal.

I wonder if there's a way to tell pm-suspend to do an S3 suspend but I have not found an answer yet.
