Detailed description：What is the hotkey for Sleep mode on the UM433D? Power button is off due to bad button placement, so I need the alternative. Last Asus I had had a Zzz key, but I don't see one on this model.

Hello EdB,
Each model design is slightly different.
The ZZZ key is only on certain model.
Hope you can understand.
Thank you.
