Power management not disabled

On my laptop I have it set to disable power management as I use a controller, but my laptop display still turns off after the period of time. Did I miss a setting somewhere for it?

The option itself doesn't work for Vista.

Using SetThreadExecutionState with the ES_DISPLAY_REQUIRED flag should work on any NT OS starting with Windows 2000, and is probably the preferred way of doing things. It should also work from limited accounts, unlike the SystemParametersInfo function.

It should probably also be used with ES_CONTINUOUS flag so the display required state persists until the next call.

does the same thing with a game controller on XP if you have the OS ask for a password on resume from screensaver/standby

Which must mean that the current scheme doesn't work, and that SetThreadExecutionState should be employed for 2000 and newer whenever.
