If you are running the computer on battery power and the
Power/Speed LED is off, flickering, or dim, most likely the
battery is low. Turn off the computer, plug in the adapter, and
then wait at least five minutes for the battery to recharge.
Then turn the computer back on. See “Using the Battery” in
Chapter 4 for instructions on how to fully recharge the battery.
If you still don’t get an image on the screen, contact your
Epson dealer.

Be sure the power switches on the computer and monitor are
turned on.
Use the controls on the monitor to adjust the brightness and
contrast.
Remove any diskette from drive A, then turn off the power
switches on the monitor and the main unit. Check that the
monitor’s power cable is securely connected to the monitor and
to an electrical outlet, and that the monitor cable is properly
connected to both the monitor and the computer. Then turn
both power switches back on.
Check to see that DIP switch 4 above the keyboard is off to
select the external monitor as the display device. Also be sure
that DIP switch 5 on the back panel is on. (See “Setting the
DIP Switches” in Chapter 1 for instructions.)
Turn off the power switches on both the computer and the
monitor. Then check the electrical outlet for power. Plug a
portable lamp into the outlet you are using for the monitor,
then turn it on to see if the outlet supplies power.
If you still don’t see an image on your color monitor after
following steps 1 through 5, contact your Epson dealer.
