JSI Tip 5588. How do I disable power management on a Windows 2000 device?

You may wish to prevent Windows 2000 from powering down a device that has gone inactive. One example might be a secure modem, that requires you to type a password. When you disconnect from the modem, Windows 2000 will power it down, forgetting your password.

Starting with Service Pack 3, Windows 2000 allows you to disable power management on any specific device.

To disable power management on a device:

1. Use Regedt32 to locate the device under the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum key.

2. Select the Parameters sub-key under the devices' key.

3. Add Value Name EnablePowerManagement, a REG_DWORD data type, and set the data value to 1 to disable power management. Deleting the EnablePowerManagement Value Name, or setting the data value to 0, will enable power management on the device.

4. Shutdown and restart Windows 2000.
