(The time to enter or exit hibernation mode depends on the computer memory size.) Creating the Hibernation File Attention: The hibernation file must not be created in a compressed data area of the hard disk. When installing an operating system or installing additional computer memory, you must create a hibernation file on the hard disk drive to use the hibernation mode. (You need to create the hibernation file only once after installing an operating system or additional memory.) The size of the hibernation file will be approximately 1MB greater than total memory. For example, if you have installed an optional 16MB memory module (DIMM) and since the base memory is 8MB, the hibernation file is 25MB: (16MB + 8MB) + 1MB = 25MB The following describes how to create a hibernation file for your operating system.
