Remap lock button?

Is there a way to remap the lock button? I have changed my battery settings so that when I click ‘Shutdown’ in the start menu, it should shut down, not go to sleep. However, I want my lock button to act as a sleep button.

Can you tell me your Serial number, so i can ask about this to tech? and also explain it a little more easy? i need to understand in order to explain it, or if you can make a video of what you want to do in the ubook would be easier :slight_smile:
