A Shorter Than Expected Battery Drive Time
Your computer may experience a shallow charge-discharge cycle characterized by
computer operation for a short period of time followed by battery charging. Repeti-
tion of such cycles will decrease your battery’s operating time temporarily. The above
should be kept in mind if you decide to run the computer off the battery after it has
been running off the AC adapter for an extended period of time.
The computer automatically determines the need for battery refreshing. In such cases,
the screen will display a message reminding you to refresh the battery, after the com-
puter has been started up. In this case, the battery indicator blinks in green to indi-
cate the need for battery refreshing. Refreshing is commenced after any key is pressed.
Also, if you leave a fully charged battery for 2 to 4 weeks in temperatures above 35°C
(95°F), the battery’s operating time may decrease temporarily.
These conditions are not due to a fault in the battery. Normal performance can gen-
erally be restored by fully charging and then discharging the battery two or three
times in succession. In order to fully discharge the battery in a short period of time, a
battery refresh tool (BATTREF.COM) is provided
(

. Please note that the
battery operating time may vary drastically depending on the types of installed op-
tions.
Battery Power
Replace the battery pack if the amount of time the computer can be operated on a full charge
drops to approximately one half of the normal duration.
NOTE
Hints on How to Use Battery Pack
If you plan to leave the computer idle for an extended period of time (approximately
two months or more), first discharge the battery using the “refresh” method, next,
charge the battery pack until the charge level reaches 50%, then remove it from the
computer and store it in a cool, dry place. (Refer to the Operating Instructions for
information on removing the battery.)
Excessive discharging of the battery can occur if it is left in the computer for ex-
tended periods of disuse, possibly shortening its service life or causing damage to
the computer. (Note that the battery will not discharge if the AC adapter is left
connected, so it does not have to be taken out in such cases.)
