CD/DVD Drive
Turning On/Off the CD/DVD Drive
When you are not using the CD/DVD drive, you can turn the drive power off to minimize power consumption.
When you want to minimize power consumption (example)
Set [CD/DVD Drive Power] in the Setup Utility to [Off].(
The drive power remains off when the computer is started up.
To use the drive, turn it on with the drive power/open switch or using [Manual Switching] in the Optical Disc Drive Power-
Saving Utility.
When finished using the drive, turn the drive power off.
NOTE
The drive power/open switch and the Optical Disc Drive Power-Saving Utility only operates after Windows has started
up.
When the drive power is turned off, the message "The 'USB Mass Storage Device' device can now be safely removed
from the system" will appear, but the CD/DVD drive is an internal device, so it cannot be removed.
If the software application may not recognize the drive, exit the software application, and then start up the application
once more after checking to make sure that the drive power is on.
