3.10 Keyboard Test 3. Tests and Diagnostics
When you execute this test, the keyboard layout is drawn on the display. When any key is
pressed, the corresponding key on the screen changes to black as shown below.
It will indicate whether the subtest is passed or failed after the question.
NOTE: The “Fn” key cannot be tested in the keyboard test. To determine whether the “Fn”
key is working correctly, press “Fn+F6 ” or “Fn+F7 ” keys to check if LCD display
brightness change gradually.
* Fn+F6 = Fn+Up , Fn+F7 = Fn+Down
