I was having problems before the battery sign desided to display an 'X'
earlier in the day the system was not regestering the trackpad's 'click'
I spoke to an apple support guy and it was sorted in about a half after a few tries of some restarting and command holding
about a couple of hours later the same 'click' problem thought it'd bloody come back! and so i tried to repeat the restarting and command holding to see if i could get my book going by myself...but then the moment i restarted the book the fan sound (a sound i had never heard my macbook make before) was there, loud, and i knew somthing was not right.
