Why Does Surface 3 Shut Off Completely After Sleeping for 1 Hour

Yeah, that's the only way to do it. For most people it won't be an issue, it's always useful to know how to disable it though

It seems that it was changed perhaps by some patch I recently installed from windows update, in the beginning as I press the power key or cover it up with keypad cover, it would go to sleep mode, that way it wakes up faster, but uses up quite proportion of battery. Now it appears to be going to hibernation mode when it sleeps too long, which definitely saves a lot of battery power, but it also takes longer time to wake up, for people like me using Surface 3 as a tablet a lot more than a laptop, it would be a problem.
