3D Ap-Key Button
The system will default to high performance video when powered by the AC/DC
adapter (the 3D Ap-Key button
will be illuminated in blue when in high perfor-
mance video mode).
If you switch from AC power to battery power the system will automatically change
to a lower performance video mode setting (the 3D Ap-Key button
will no longer
be illuminated in blue). High Performance Video can not be enabled when the
system is battery powered.
The system will retain in memory the last known video performance setting if you
switch back from battery to AC power.
