I've recently been having issues with my laptop freezing when coming out of standby, so I wanted to reset my PRAM and SMC. When I went to go reset the PRAM (Shut off, held down Command, Option, P, R, Power On) it just goes straight to OSX. I also tried booting into diagnostics by holding down D and also tried pressing F2 as seen elsewhere, without success. So, what's going on with it? I can't tell if the SMC resets, but I will try to figure it out later.
