This happens whenever I switch on my wall socket. It automatically turns itself on without me pressing anything...is anyone able to explain this and give me a solution? I have run the PRAM and NVRAM Reset test but this did not solve the problem. I attempted to run the SMC Reset test but am unable to wait 5 seconds as per step 5 (see 'Resetting the SMC for Mac Pro' section at http://support.apple.com/kb/HT3964 ) - when I re-attach the power cord back into the machine, it boots itself up immediately. Thanks in advance!
