Removing the front case and/or replacing the display (2.4 GHz)
1. Unplug the display cable from connector J4 and keyboard cable from connector J3.
2. Remove main board, subframe, and radio card (as one assembly) from the front case.
3. Remove the display from the front case by lifting the rubber cushions.
4. If you are installing a new display, remove and save the rubber cushions.
5. Set the display down on a clean surface with the circuit board side facing up.
Caution Do not separate the main board, the subframe, and the radio card.
They are not serviceable. Separation will damage the single-use antenna
connector, which can be replaced only at the factory.
Caution Do not bend or stress the display flex cable, especially at its
connection to the circuit board.
Caution Do not touch the display screen. Fingerprints are difficult to remove
without damaging the display.
