That is for your front switches and lights the one you are looking for has no wire comming out of it, I still have a few dead e-machine motherboards here. What you should be looking for is a black or white jumper block. connected to 2 pins out of 3 next to it should say CMOC or bios configuration. If you can not find this just remove the cmoc battery for 20min and put it back and see what happens. I have fix over 70 e-machines in the past year with the same problem and 90% had to have the power supply and board replaced.
