My sis is building a computer and there is a connection on the case called M/B SW. I was just wondering if any of you know what this switch is for?

Well the board has a positive and negative led connector for the reset. The case also has a reset connection.

The problem is... she doesn't know where to connect the M/B SW to the motherboard and once that switcth is not connected, nothing comes on. But, she haven't figure out where to connect it on the board cause she can't get the computer to start up yet.

Any ideas or advice will be appreciated. Thanks all...
