Removing The Heatsink (Hp Authorized Service Providers Only) - HP OmniBook 7100 Service Manual

1. Lay the keyboard on the case slightly forward of its normal position, then connect the
pointing stick cable (smaller cable).
2. Lean the keyboard against the display, then connect the keyboard cable (larger cable).
Caution
Before inserting the keyboard into the case, tuck the excess length of the keyboard flex cable
under the top case behind the keyboard. Then pull the free end of the stiffener tab on the cable
toward the front of the case—so the tab is not under the top case. Check the cable again after
lowering the keyboard into its final position.
• When you lower the keyboard into the case, pull it toward the front so the three tabs at the back fit
down into the case. Adjust the keyboard until the tabs lock under the top case.
