I checked my sleep settings and that's not it! Basically, the only way to turn the screen on again is to hold on button for 7-10 seconds and then press it once quickly. It doesn't look like it is booting up, just takes a minute before it lets me use mouse and type. Is it really bad to do this almost every time I use it? Anything I am missing here? The MacBook I have is only 6 months old...
