I hope my response to David Gilbert answered this, as well. S4 is "hibernate" and S3 is suspend. S1 simply stops the CPU clock and is, as far as I can tell, useless. Since your system lacks S3, it does not look like suspend is an option. Most systems don't come with a hibernation partition as hibernation is a BIOS function and Windows now has the ability to hibernate to a file in any Windows partition. Try checking with the manufacturer's web site or tech support to see if they have a tool to do this or information on using fdisk to do it. Since your BIOS lists S4, it should do it. I believe that all that is required is a slice slightly bigger (one page bigger?) than the total memory size with a special type field (not FAT32, FAT16, NTFS, FreeBSD or any other normal ID). BIOS sees this in the partition table for the disk and initiates the memory dump when S4 is requested. If no suitable partition is found, it should ignore the request. -- R.
