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 Ctrl, Alt, and
Del. The Windows® Logon screen appears. Click the red arrow
button ( ) in the lower-right corner of the desktop to display the
Shut down options, and then select Restore to restart the computer.

The AC power light is blinking.
If the AC power light is blinking, try the following steps:
1Cut off power to the computer by disconnecting the AC adaptor
and removing the battery. The error condition will be
interrupted, and the AC power light will stop flashing.

If the AC power light starts flashing, remove the battery, and
continue with the steps below.

“trickle-charge” to the battery. Once the battery has been
trickle-charged, it may begin working correctly again.
If the trickle-charging does not prove effective, visit the
Toshiba Web site at pcsupport.toshiba.com and see the Support
Bulletin Step-Charging the computer’s battery (click the
Ask Iris® link and search for the support bulletin by name).
4Connect the AC adaptor to a different power outlet, preferably
in a different room. If the computer starts normally, there may
be a problem with the AC outlet itself, or the voltage level
available from it.
5Verify that the AC adaptor is the correct unit for your computer
model. The computer may not be able to start from an AC
adaptor that is rated for less current (amperage) than the
computer requires, even if the rated voltage is correct, and the
