Standard External Connectors
Inside the case of any computer several cables and plugs have to be connected.
These cables and plugs are usually connected one-by-one to connectors located on
the mainboard. You need to carefully pay attention to any connection orientation
the cables may have and, if any, notice the position of the first pin of the connector.
In the explanations that follow, we will describe the significance of the first pin.

This connector has a specific orientation. Connect the five-thread keylock
connector cable to the connector pins on the mainboard.

The

is used to lock the computer
’
s keyboard.
This disables the keyboard so that unauthorized persons cannot
use it. When this function is in use, you will need to use the
unlock key to activate the keyboard.
Hardware Suspend switch
There is no specific orientation. Connect the two-thread hardware suspend plug
to the connector pins on the mainboard. Since most cases do not support this
feature, most of you ignore this instruction. Furthermore, this feature is not
necessary as it is already a part of the mainboard.
