Gently unclasp and unplug the four connectors by first lifting the black locking bars of the ZIF connectors.

The black locking tables can be lifted by using something small such as a fingernail.

There may be black tape covering the ribbon cables that need to be removed.

Be gentle while dealing with ribbon connectors since if damaged will cause malfunction.

When reassembling, make sure that each ribbon connector is completely inserted before lowering the black tab.
