Diagnostic LED - what order?

crwdns2934249:0crwdne2934249:0:

Hi -

I'm trying to figure out the sequence of the LED's. Is #1 at the top, looking at the computer the right way up, or at the bottom? I ask because the bottom one is lit while none of the others are, but it would seem odd for only LED 4 to be lit.  The computer does nothing upon pressing the start-up button. It also makes a slight buzzing sound from the power supply when plugged to power. Any suggestions would be most appreciated. Thanks
