– Ambient temperature is too low
(approx. 10 °C (50 °F) or lower).
– Ambient temperature is too high
(approx. 35 °C (95 °F) or higher).
– There is a problem with the battery.
Firstly, try charging the battery in a
suitable temperature range. If the
problem persists, consult your nearest
Sony dealer.
Notes
 If the battery is not used for a long time,
battery may be quickly depleted, however,
after a few recharges, battery life will
improve.
 When you do not use the unit for a long
time, charge the rechargeable battery at
least biannually to avoid the deterioration
of the battery.
 If the battery is not used for a long time,
charging may take more time.
 If the life of the built-in rechargeable
battery drops to half the normal length,
the battery should be replaced. Consult
your nearest Sony dealer for replacement
of the rechargeable battery.
 Avoid exposure to temperature extremes,
direct sunlight, moisture, sand, dust or
mechanical shock. Never leave in a car
parked in the sun.
 If the computer enters hibernation mode
while connected to the carrying case,
charging will not be completed properly.
Check the setting of the computer before
charging. The indicator will go off
automatically even if the computer enters
hibernation mode. Charge the unit again
in this case.
 Use the supplied USB cable only, and
connect the carrying case directly to a
computer. Charging will not be completed
properly by an indirect connection, such
as via a USB hub. Continued
