first purchased.  Be sure to charge it before using it for 
the first time.  When the AC adaptor is connected to 
the computer, charging begins automatically.
zShould the battery leak and the fluid get into your 
eyes, do not rub your eyes.  Immediately flush your 
eyes with clear water and see a doctor for medical 
treatment as soon as possible.
NOTE
zThe battery pack may become warm during 
recharging or normal use.  This is completely nor-
mal.
zRecharging will not commence if internal tempera-
ture of the battery pack is outside of the allowable 
temperature range (0 °C to 55 °C {32 °F to 131 
°F}). (Î Battery Power in onscreen Reference 
Manual)  Once the allowable range requirement is 
satisfied, charging begins automatically.  Note that 
the recharging time varies based on the usage 
conditions. (Recharging takes longer than usual 
when the temperature is 10 °C {50 °F} or below.)
zIf the temperature is low, the operating time is 
shortened.  Only use the computer within the 
allowable temperature range.
zThe battery pack is a consumable item.  If the 
amount of time the computer can be run by using a 
particular battery pack becomes dramatically 
shorter and repeated recharging does not restore 
its performance, the battery pack should be 
replaced with a new one.  
zWhen transporting a spare battery inside a pack-
age, briefcase, etc., it is recommended that it be 
placed in a plastic bag so that its contacts are pro-
tected.
zAlways power off the computer when it is not in 
use. Leaving the computer on when the AC adap-
tor is not connected will exhaust the remaining bat-
tery capacity.
