Solder points for 12v Led

Hi just thought i would reach out for some help, I have a Xbox one 1540. I have been looking for a point that would trigger a transistor on and off for some LED lights while the Xbox is set to instant on mode. the I was trying to use a connection I found that also triggers the fan, but the fan does not work if I use that point.

Basically looking for a point that has a zero voltage when the Xbox is OFF and when ON has 1volt or higher. When set to instant on mode.
