I can get some kind of suspend state working using 'echo 1 >/proc/acpi/sleep' but I don't think it's the genuine suspend-to-RAM state. For one thing, as soon as I put it into this state, one of the fans comes on and stays on (not very good when you're trying to conserve battery juice, but this is probably a Dell BIOS problem); and secondly, the screen doesn't actually seem to be turned off - I can still make out an image on it, it just looks like the backlighting has been turned off. Nothing at all seems to happen if I try to echo 3, 4, 4b or 5 to /proc/acpi/sleep, which is strange since the ChangeLog for the latest ACPI patch mentions being able to change settings for the S3 suspend, and it also claims to incorporate the s4bios patch. If I cat /proc/acpi/sleep I get "S0 S1 S3 S4 S5", so I'm not sure if I'm doing something wrong, or if ACPI suspend-to-RAM support isn't fully functional yet. So I'm wondering if anyone can give me any hints about getting these real suspend states to work? Any information would be much appreciated. -Luke ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com
