Display Problems
Nothing appears on the screen.
During operation, the screen may automatically turn off as a result of
power management. Press any key to see if the screen comes back.
The brightness level might be too low. Increase the brightness.
The display output might be set to an external device. To switch the
display back to the LCD, press the
Fn+F5
hot key or change the display
through the
Display Settings
Properties.
The characters on the screen are dim.
Adjust the brightness and/or contrast.
The display brightness cannot be increased.
As a protection, the display brightness will be fixed at a low level when
the surrounding temperature is too high or too low. It is not a malfunction
in this situation.
Bad dots appear on the display at all times.
A small number of missing, discolored, or bright dots on the screen are
an intrinsic characteristic of TFT LCD technology. It is not regarded as a
LCD defect.
Clouding (or called “mura”) happens on the screen when you exert
forces
on
the left or right side of the LCD frame.
This is a normal phenomenon, not a defect.
Fingerprint Scanner Problems
The following message appears during the fingerprint enrollment
process – “Your device is having trouble recognizing you. Make sure
your sensor is clean.”
When enrolling a fingerprint, make sure you move your finger slightly
between each reading. Not moving or moving too much can both result
in fingerprint reading failures.
