<p>A method for managing the power consumed by a disk drive in a portable laptop computer which includes quantizing predetermined periods of disk inactivity into states which are stored in a state table in memory. Based upon a history of disk accesses by a user, the number of transitions between each pair of states is counted and stored in memory. In view of this history, a future period of disk inactivity can be predicted and said prediction is compared with a threshold value. If the predicted period of disk inactivity is greater than the threshold value, the computer is automatically placed in a low power mode by spinning down the disk. If not, the disk continues to spin.</p> |
