Starting and booting
Symptom:
The VIPER will not power up from the AC
adapter.
Make sure that:
• The AC LED on the lower left of the display housing is on
after pushing the power button.
• The AC adapter is securely plugged into the VIPER 's power
input socket, and the AC adapter's power cord is securely
plugged into both the AC adapter and the AC outlet.
• Power is available at the wall outlet (use a lamp to test it).
Symptom:
The VIPER will not power-up from the bat-
tery.
Make sure that:
• The AC LED on the lower left of the display housing is on
after pushing the power button.
• The battery is correctly installed in the battery compartment.
See Using batteries on page 26 and Battery maintenance on
page 87 for more information.
• The battery is fully charged. To be sure, remove the battery and
press the QuickCheck button on the top. If the battery is fully
charged, all the lights on the drawing of the battery will be
green. If it is partially charged, the number of green lights indi-
cates the relative amount of charge the battery carries. No
green lights means the battery is not charged.
