Method and system for managing computer low power mode

Abstract

A computer system and methods for determining whether to compress the content of memory in a computer system, optionally including video memory, prior to storing the contents of memory within a non-volatile storage device prior to entering a hibernation mode where power is disabled to memory. An evaluation of the actual performance of computer system speed in storing and retrieving a file having the content of memory and decompressing the file is made to determine whether time is saved as a result of reducing the size of the file by compressing as compared to the time to compress and decompress the file. The evaluation of actual computer system performance takes place after each exit from hibernation mode and a determination is made whether to compress the content of memory the next time a hibernation mode request occurs in response to that evaluation.
