O CHECK INTERNAL COMPONENTS
1. Shut down and open the E-8100 (see pages 46 and 48 ).
2. Before you touch any components inside the E-8100, attach a grounding strap to your wrist
and discharge any static electricity on your body by touching a metal part of the E-8100.
3. Inspect the inside of the E-8100 (see Figure 9 on page 43).
Make sure that no foreign materials have been dropped into the chassis.
• Look for obviously loose boards and reseat each board securely in its connector on
the motherboard.
• Look for obviously loose cables and reseat each cable connector firmly.
• Make sure that each connector is properly aligned with its mating connector. If the pins
are offset from each other, the affected board will not function properly.
4. Reassemble the E-8100 and verify its functionality (see page 99 ).
