IMPORTANT NOTIFICATIONS

• Wake-on-Wireless LAN (WoWLAN) is not supported
• Hot plug and audio via the HDMI Out port is not
supported. If you want to extend the image via HDMI
cable, plug the HDMI cable into the HDMI Out port
first and then turn on the OPS.
• In order to use RTC alarm, make sure that your
Windows configuration is set correctly. Enter the
Control Center > Power Options menu and click
on "Choose what the power buttons do" first.
Then click on "Change settings that are currently
unavailable" and make sure that the "Turn on fast
startup(recommended)" option is unchecked.
• If only admin password is set, you can enter the
BIOS by simply clicking on "Enter" when password
window pops up to avoid a deadlock in case the
password has been forgotten. If you do not want that,
you should set both admin and user passwords. This
way, you will not be able to enter BIOS by clicking on
"Enter" when password window pops up.
• Ubuntu Usage
In some versions of Ubuntu Operating System
the platform in which the OPS is plugged may be
detected as a second screen due to the HDMI Out
port on the OPS.
In case of no signal or no menu is displayed
on settings screen or only the background is
displayed after Ubuntu installation, enter the BIOS
> Advanced > Power Configuration menu and
disable EDP to HDMI option. In this case, you can
see Ubuntu screen normally but you will not be able
to use HDMI Out port of the OPS.
Alternatively, you can keep the Windows button
pressed down and press the button "P" consecutively
