Any way to auto-off the screen without S2U2/Equiv Program

[robertkmagill]

What i want is a very basic program or registry change that will shut
Off the screen after 5 seconds like S2U2 does. It drives me nuts that
the phone turns on randomly (regardless of roaming/tower changes).
Because when it does, And its in my pocket, The phone will just suck
down the battery as my pocket constantly touches stuff on the screen.

I loved that 5 second/screen off thing that S2U2 does.
But i find it silly that i have to install a memory-hogging program that
does something windows should allready have. I have used all versions
of S2U2 before, And just find that it slows down the phone, And doesnt
answer properly every once in awhile. That is a pain in the rear when
a client calls me from an unlisted number that i can't simply call back.

Sooo, Any advice on a 5 second auto shutoff option that also keeps
the screen locked at the same time?? Keep in mind, That i have Searched.
And haven't seen much about how to pull it off.
