TROUBLESHOOTING 123
Checking internal components
To check the internal components, you must remove the side and front panels of the E-41.
Before you remove the E-41 panels, be aware of the safety precautions that you should take
when handling the E-41. Use standard ESD precautions when handling printed circuit boards
and electronic components. To review the safety precautions, see “Precautions” on page 14.
See the disassembly procedures on page 51 and the reassembly procedures on page 104.
TO 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).
