Troubleshooting
Dealing with Problems (Summary)No display after powering on
The power has not been
turned off, but after a cer-
tain period of time, there is
no display
When the battery pack is
used, the screen is darker
than when the AC adaptor
is connected
The LCD brightness changes
a number of times when the
AC adaptor is disconnected
Image colors are not repro-
duced as expected when dis-
playing photographs or
other images
When there is no display to an external display,
•Check your cable connection to the external display.
•Confirm your display is powered on.
•Check the settings for your external display.
The display destination may be set to the external display.
Try changing the display destination by pressing Fn + F3 .

Has the computer been set to the power-saving mode?
To resume operation of your computer from the condition the power of the display is off
(for energy conservation purposes), press any key unrelated to the direct triggering of a
selection, like Ctrl .
To save power, your computer may have automatically entered the standby mode (power
indicator blinks green) or hibernation mode (power indicator turns off). In such cases,
press the power switch.
Press Fn + F2 and adjust the LCD brightness. Note, however, that when the LCD
brightness is increased, the battery running time will become shorter.
The LCD brightness can be set to separate levels for when the AC adaptor is connected
and when it is disconnected.
Intel(R) Display Power Saving Technology ( “Computing on the Road”) is
active and automatically changes the LCD brightness.
We recommend removing the check mark from [Intel(R) Display Power Saving Technol-
ogy]. ( “Computing on the Road”)
