Non-System disk or disk error message.
Make sure there is no diskette in the optional external diskette
drive. If there is a diskette in the drive, remove it and press any key
to continue. If pressing any key does not work, press

The AC power light is blinking.
If the AC power light is blinking, try the following steps:

If the AC power light starts flashing, remove the battery, and

trickle-charged, it may begin working correctly again.
If the trickle-charging does not prove effective, visit the

adaptor that is rated for less current (amperage) than the
computer requires, even if the rated voltage is correct, and the
