MacBook Pro won't turn on … KB helps

I have been a mac user now for a little over 1 year – going on 2 I guess.

I have been happy thus far with my experience – however for 2 days I have not been able to power on my macbook pro.

Kinda frustrating.

I mozied on over to the apple website and simply typed into the search tool my serial number and then – cant boot – I am given a simple procedure http://support.apple.com/kb/HT1411

Voila – it worked very well  I am pretty pleased that the support channel online works so well. Now if I could only say the same for HP and that ML350 Server we are having issues loading an OS onto.
