Disable hibernate / suspend on desktop Dell Inspiron 531s
 

I recently purchase a Dell Inspiron 531s and installed Mandriva 2007 Spring. Everything works well, except when I leave the room, and come back about 15 mins later. The system goes into hibernate / sleep / suspense and locks up. It locks up to the point that I need to force a hard reboot to get back up.

I'm going to be moving this server over to replace an old web server I've been using for about 5 years, but I need it up and running 100% of the time (well at least as close as possible) and it seems whenever I stop using it, after 15 mins, it dies. No response to ping / FTP / SSH, just gone, and it needs a hard reboot. Obviously not ideal.

I've found some documentation stating that I need to change the power settings in the Display Settings, which I've done. I've also been told that there's a setting in the BIOS to lookout for, but I can't find it.

Does anyone know what I may be missing here? Any help is greatly appreciated.

Thanks

I've been looking all around now for help on this. It's extremely frustrating to have my box lock up after 5 minutes of non-use. ;)

I was looking around and thought maybe adding some kernel parameters would do the trick "noapci" etc, but alas, those changes were in vain.

I've tried installing other distros now (ubuntu and Fedora) but I'm not as familiar with them and would prefer to use Mandriva. When I had Fedora running, I didn't have any problems (at least with the system hanging on me) even after 4 hours.

If anyone has insight, links, articles or knows what I'm missing here, I'd really appreciate it.

Again, trying to run Mandriva 2007.1 Spring on a Dell Inspiron 531s with AMD64

Thanks

Just wanted to follow up with a solution that seems to be working so far...

To stop my computer from freezing up on hibernate, I disabled most (if not all) of the power management using kernel params on boot. I edited my /boot/grub/menu.lst file to have this as the first line...

note the acpi=no, noapic, nolapic and apm=off

Next, I went into the Control Center->Peripherals->Display settings and disabled all the settings in the "Power Control" tab.

So far, I have yet to go into hibernation / sleep / suspense, and everything is working well. Keeping my fingers crossed!

If anyone sees any problems / issues with what I did, or has some helpful advice, please post! ;)

Thanks
