Okay, I have a problem, I dunno if it has something to do with the MacBook itself, though it wouldn't surprise me, or whether it's something I've done. I picked up a 2.0GHz model yesterday, and after a quick trial, I immediately popped off the back panel and replaced the stock HDD with a shiny new OCZ CoreV2 SSD and reinstalled the OS, Now; I used this SSD in an old MacBook and had no issues, so I'm wondering if maybe it's something to do with this new build of OSX or not. Now, here be my problem, whenever I go to Apple > Shutdown the machine shutdowns down and then boots straight away! - It's almost as if I've clicked 'Restart' instead (which I haven't). This, coupled with a *slightly* wiggly battery cover and slopy function keys is doing my nut. I may swap the unit out, but I want to know that I'm not going to have the same random reboot on shutdown errors with another one, any ideas on what may be the cause of this?
