Hard Disk Does Not Spin Down According to the Power Management Settings (241679)

SYMPTOMS

The hard disk on your laptop computer may spin continuously, even though no programs are accessing it after the time that is specified in the Power Management tool.

This problem can occur when your battery is charging (after being on battery power), or discharging (when the computer is running on battery power).

CAUSE

This problem can occur because all programs are notified by a power broadcast message every time that the battery life percent changes; however, the Input Output Supervisor (IOS) resets the spin-down timer for the device whenever it receives the broadcast message.
