Most laptops have a feature where all the contents of the RAM is stored to disk, either in a file or partition, so that nothing is lost if the computer automatically shuts down due to low battery power. If it's working properly when you reboot, it should open exactly as it was when it turned off. The message you are getting indicates that your laptop save to disk needs a partition and can't find it, so the message is a warning that the feature isn't working. Susdisk.exe is probably a utility that configures the partition, it may be on your driver disk, or you may need to search the net for a copy. I can't offer any advice on how to use susdisk as my laptop has Phoenix BIOS and that uses PHdisk instead.
