Computer turning off

[Dlee45]

I recently just bought a macbook and whenever I leave my computer on for a long period of time or when it comes back from sleep mode it makes me manually turn off the computer, like it tell me to hold down the power button and turn it off. This really annoys me because I dont know who messaged me when I was gone. Am I doing something wrong that would make my macbook do this?

so you cant press the power button for a second and it comes up with options to shut down, restart or sleep ?

try reparing the permissions. - I THINK THIS WILL HELP
