Another tip – adding sleep button:
I find the power button on the tablet a bit flimsy. Tried to do software shortcut, but SetSuspendState Sleep or the PsShutdown don’t work, instead it hibernates. So the only option I found is to emulate keypress Alt+F4.
Here is a simple way to make a shortcut for Sleep and add to Start menu in Windows:
You need automation tools such as AutoHotkey or Robotask. Create new task. You need to press the Alt+F4 keys on desktop, otherwise it just closes the topmost window. To do that, add task to open shortcut %windir%\explorer.exe shell:::{3080F90D-D7AD-11D9-BD98-0000947B0257}. After that just add stops .. press ALT+F4, up and up and Enter.
Make a shortcut and Startup button.
Voila.
(The Hibernation still works via SetSuspendState. )
