Does anyone know if OS X logs the last time your CPU has been booted up? In Apple System Profiler, under Logs, there is an item named 'Console Log' but mine is only showing me the current Boot and not any previous Boots. I am curious if anyone else has been using my computer because my surge protector has been mysteriously on a few mornings. I'm in my 30s and I don't have 'brainfade' yet that I would forget that I did it!
