Troubleshooting Your System
9 Reconnect the system to its electrical outlet, and turn on the system and
attached peripherals.
10 Enter the System Setup program and check the system memory setting.
See "Using the System Setup Program" on page 45.
If the amount of memory installed still does not match the system
memory setting, then proceed to the next step.
11 Turn off the system and attached peripherals, and disconnect the system
from its electrical outlet.
12 Open the system. See "Opening and Closing the System" on page 67.
NOTE:
Several configurations for memory modules exist; see ""General Memory
Module Installation Guidelines" on page 94.
13 If 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 97.
14 Close the system. See "Opening and Closing the System" on page 67.
15 Reconnect the system to its electrical outlet, and turn on the system and
attached peripherals.
16 As the system boots, observe any error message that appears and the
diagnostic indicators on the front of the system.
17 If 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 181.
