ACPI Sleep Button Does Not Wake Computer (305826)

SYMPTOMS

If your Advanced Configuration and Power Interface (ACPI) compliant computer entered Standby mode automatically, it may not resume from Standby mode when you press the ACPI SLEEP button. Typically, the hard disk spins up, and then immediately spins down.

Notes

After this problem occurs, moving the mouse typically wakes the computer.
When the problem occurs, pressing the ACPI SLEEP button puts the computer into the S1 sleeping state (which it is already in), instead of waking it up, and this is why the hard disk spins up and down.

MORE INFORMATION

This problem does not occur if the computer was put into Standby mode from the Start menu, or by pressing the ACPI SLEEP button.

Automatic entry into Standby mode occurs if the computer is idle for an amount of time that was previously configured in the Power Options tool in Control Panel.

The technical ACPI term for Standby is "S1 Sleeping State."
