Epson Endeavor 468C - Manual (Page 146)

Keyboard Problems
If you have trouble with the keyboard, check the following:
1. If the screen displays a keyboard error message when you
turn on or reset the computer, make sure the keyboard is
securely connected to the correct port. See “Connecting the
Keyboard” in Chapter 1 for instructions.
2. If nothing happens when you type on the keyboard, see
“The Computer Does Not Respond,” above.
3. If the cursor keys on the numeric keypad do not work
properly, the num lock function may be on. When num lock
is on, the keys on the numeric keypad work only as
numbers. If the Num Lock upper right corner of
the keyboard is lit, press to turn off the function.
If you want to change the initial num lock setting, see
“Setting the NumLock Boot Status” in Chapter 2.
4. If you still have trouble with the keyboard, contact the Epson
Connection for assistance.
Monitor Problems
For monitor problems, check the following:
1. If there is no display on the screen, check that the monitor’s
power switch is on and that its power light is lit. If the
power light is on but you still do not see anything on the
screen, check the brightness and contrast controls.
2. If the power switch is on but the power light is not, turn off
the monitor’s power, wait five seconds, and turn it back on.
Wait to see if the screen displays any text.
