Problems with Display

darker
z Press the
Fn
+
F2
key. This makes the screen lighter.
z If the screen becomes darker after disconnecting the AC adaptor:
The computer has different set brightness levels for when the AC adaptor is
connected and for when it is not connected. If you press the
Fn
+
F2
key to
increase the brightness when the AC adaptor is not connected, this bright-
ness is maintained, and determines the brightness next time the AC adap-
tor is disconnected.
(Making the display brighter shortens the battery operating time.)
An afterimage appears (e.g., the key
green, red, and blue dots remain on
the display) or there are dots not dis-
playing the correct colors
z If an image is displayed for a prolonged period of time, an afterimage may
appear. This is not a malfunction. The afterimage will disappear when a dif-
ferent screen is displayed.
z High-precision and advanced technologies are used in the production of
color liquid crystal displays (color LCDs). Therefore, if 0.002% or less of the
picture’s elements either fail to light or remain constantly lit (that means that
more than 99.998% of the elements are functioning properly), this is not
considered a defect.
