Troubleshooting an Optical Drive

10Enter the System Setup program and check the system memory setting. See "Using the System Setup Program" on page 43.

If the amount of memory installed still does not match the system memory setting, then proceed to the next step.

11Turn off the system and attached peripherals, and disconnect the system from its electrical outlet.

12Open the system. See "Opening and Closing the System" on page 65.

NOTE: Several configurations for memory modules exist; see ""General Memory Module Installation Guidelines" on page 92.

13If a diagnostic test or error message indicates a specific memory module as faulty, swap or replace the module. Otherwise, swap the memory module in socket 1 with a module of the same type and capacity that is known to be good. See "Installing Memory Modules" on page 95.

14Close the system. See "Opening and Closing the System" on page 65.

15Reconnect the system to its electrical outlet, and turn on the system and attached peripherals.

16As the system boots, observe any error message that appears and the diagnostic indicators on the front of the system.

17If the memory problem is still indicated, repeat step 11 through step 16 for each memory module installed.

If the problem persists after all memory modules have been checked, see "Getting Help" on page 179.
