I assume your trying to save battery and put the phone back in its case?

To save the battery just hold the top power button down adn it will dim the screen.

There is no real way to lock the buttons and have the software still work unless you go to freecabs.de and find their screen lock software.

Use it carefully, you have to hold two buttons down to get it to unlock and it wont always unlock for you.
