Then pull up the other end without totally removing it.
This way, you do not mis align the pins and damage the board. If you do, or you install it back wrong, the board may be damaged beyond repair.
The connector is about 1 and a half inches long and it is white with a ribbon cable in between. You shoul be able to ID it by following the route from the CD drive unit to the board. The same procedure is used on the drves as well.
I am only going to mess with the connector, right, not the power supply?
