O CHECK INTERNAL COMPONENTS
1. Shut down, and then open the E-41 (see pages 49 and 51 ).
2. Before you touch any components inside the E-41, attach a grounding strap to your wrist and
discharge any static electricity on your body by touching a metal part of the E-41.
3. Inspect the inside of the E-41 (see Figure 12 on page 48 ).
Make sure that no foreign materials have been dropped into the chassis.
• Make sure that the DVD and HDD data cables are connected to the correct SATA
connectors on the motherboard (see Figure 12 on page 48 ):
– DVD drive power/data combination cable to motherboard connector SATA 1
– HDD data cable to motherboard connector SATA 2
• 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-41 and verify its functionality (see page 104 ).
