Hi folks !

Maybe it's not possible but i just wanted to be sure.

Is there a way to set a particular time, the system should startup ?

Or, is it possible to throw the system in a "sleep" mode and restart it after a amount of time is gone ?

I'm using Fedora Core 2.

Thanks in advance, Wolfi.

I believe you can set a cron job with sleep to get what you are after

I've been trying to figure this one too. If you find anything Holla please.

Thanks

Assuming you're talking about bringing the system totally down ("shutdown") and then having it reboot itself automatically, I don't know of any direct way. I think you will need some external stimulus.

I've never used this feature, but I know some systems have a "wake on LAN" capability. But this requires an external stimulus via the network. And the system is not totally down I don't think - it's in some kind of sleep mode. Again, I've never used this capability so I really don't know the details. You could research it yourself.

Another possibility is to set your BIOS to start booting when mains power is detected. Then you could use some external device to turn the power on (an X10 Appliance Module, or something like that). You would need an external timer as well. I wouldn't do this myself, too much potential for problems if the X10 device inadvertantly received an OFF command or screwed up with line noise.

Personally, I just leave my systems running 24x7. They're on a UPS that will shut them down cleanly if a power failure occurs. Most CRT monitors these days can be idled down to a low power state, LCD monitors don't draw much power anyway, and when their backlight kicks off, power draw is minimal.

Now, after all that, if your question was not about system shutdown/startup and you were really interested in simply running a program at a preset time ... investigate the "crontab" and "at" commands.

For me there's a "Auto Power" option under "Power Management" in the BIOS that allows me to choose the time, and days, that the computer will turn itself on.
