Keyboard Test

To execute the Keyboard Test, select 3-KEYBOARD TEST from the DIAGNOSTIC TEST
MENU, press Enter and follow the directions on the screen. The Keyboard test contains six
subtests that test the computer's keyboard actions. Move the highlight bar to the subtest you want
to execute and press Enter.
Subtest 01 Pressed Key Display
When you execute this subtest, the keyboard layout is drawn on the display as
shown below. When any key is pressed, the corresponding key on the screen
changes to the key character that was pressed. Holding a key down enables the
auto-repeat function which causes the key's display character to blink.
To exit this test, press Del+Enter.
Subtest 02 Pressed Key Code Display
When a key is pressed, the scan code, character code, and key top name are
displayed on the screen in the format shown below. The Ins Lock, Caps Lock,
Num Lock, Scroll Lock, Alt, Ctrl, Left Shift, and Right Shift keys are
displayed in reverse screen mode when pressed. The scan codes, character codes,
and key top names are shown in Appendix D.
