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.
