Hello aunglina6

As i can see from the picture of your motherboard the connections are at the bottom close to the battery. it looks like this

o o o o 1 2 3 4
o o o o o 5 6 7 8 9

this is just to give you the idea how it is set up.

9 is no connection

8 + 7 is reset switch, 6 + 5 is hard disk LED with 5 the positive of + side.
1 + 2 is power LED with 1 the positive or + side, 3 + 4 is the power switch.

with the reset and the power switch don't worry about the positive or + side. it makes no difference.

good luck.
