JSI Tip 7383. How do I determine the Advanced Power Management status of my computer?

Starting with Windows 2000, the Support Tools on the Windows CD-ROM have contained Apmstat.exe, which is used to determine the APM status of your computer.

NOTE: The Windows XP and Windows Server 2003 Support Tools also contain Apmstat.exe.

When you type Apmstat /?, you receive:

apmstat \[-v\]
-v for vebose mode

The possible outputs include:
