Hardware Diagnostics
NOTE
If you run a memory diagnostic check after installing a new RAM module (sold separately) and the message "Check
Result TEST FAILED" is displayed:
Remove the additional RAM module and run the diagnostic check again. If the message "Check Result TEST
FAILED" is still displayed, you can assume that there is a problem with the internal RAM module.
9 After the diagnostic check is complete, click
restart the computer.
NOTE
When you set [Optical Drive Power] to [On] in the [Main] menu of Setup Utility, you will hear operation sound from
CD/DVD drive soon after the computer starts the startup procedure. To avoid the sound when the computer is start-
ing up, set [Optical Drive Power] to [Off].
