Suspend to RAM:

This is the easier thing to do: simply build your kernel w/ APM enable (as module or not). There is no other required option. To test: press Fn + Ecape

Suspend to disc:

• This part is little more tricky.
• First download http://support.dell.com/filelib/format.aspx?releaseid=r22768 > (Suspend to Disk Util for Dell)
• This is a .exe ok .. but just unzip it (yes it’s a self-extractable zip file)
• Take a empty floppy, run ./setup.sh
• This will make a dos boot disk w/ all required tools on
• So it’s time to reboot on this floppy
• Here you will get a dos prompt
• Run mk2sd.exe (this will make a special hibernation partition)
• Important Note : This partition must be in the first cylinders of the hard drive. DOS has old restrictions about the partition size .. (I used partimage and parted to find the right place for this)
• So that’s all
• reboot Linux and press FN+A (Q on azerty keyboard) to test :)

– Enjoy hibernation …
