Give me a second, and I can probably get a reading for you.
Power display, and HDD activity pins should be around 3V, as they run LED's on their own.
Crap... Too dark in there, I can't get a reading.
Sorry man. I'd guess it would be 3.3V, that would make sense to me.

Edit: one of the prongs just fell off my multimeter. May have been the reason I couldn't get a reading...

aww damn D: can u fix it? and the led's i looked at on ebay are 3.5v
I have a packet from DSE in front of me that says 3.2V operating range.
The ones in my DVD drive are setup to draw 3.2V

Note: LED's should work above 2.2V. A lot will burn out going above 3.5V though. Blue ones are usually rated higher, as they use more energy

These are the ones in front of me: http://www.dse.com.au/cgi-bin/dse.st...uct/View/Z3009
