Thanks for the hint, that sounds promising. However, I didn’t have /sys/classes/rtc and since I didn’t know what I need for my ICH-7 chipset, I compiled everything I could find under Device Drivers/RTC. Then I loaded all those modules, but apart from an empty directory /sys/classes/rtc, the only reaction at all that I got in my syslog was: kernel: rtc_cmos: probe of 00:07 failed with error -16 :( Well, I’ll dig into it further... -- Gruß | Greetings | Qapla' I decided to go on a strict diet.

That must be there otherwise the content goes away if you try and resume. So what part of the machine is powered to be able to wake it up? PCs don't have alarm clocks, the on-board clock can't usually do it, so the only option is for some code to be running, polling the time and cause the system to wake up. Which is exactly what suspend does not do. PCs have a BIOS feature that allows them to be woken at a specific time. I think you can use Linux to set that time, then hibernate; I'm not sure about sleep. It's certainly common amongst MythTV users to set their machines to go into a low-power mode and then wake them in time to record a TV show, but I don't know the mechanics.

[gentoo-user] Scheduled wakeup from suspend to ram
Hi Group one of the very last things I still need Win***s for is to wake me up in the morning: I set up a task schedule to launch a playlist with Winamp. Do you know of any way to let my laptop go on again automatically after I put it to sleep in its RAM? In case it helps: I'm running 32 bit i686, version 2.6.30.
