Appendix Troubleshooting Useful Information Getting Started
Precautions (Battery Pack)
Do Not Use with Any Other Computer
The battery pack is rechargeable and was intended for the specified computer or charger. If it is used with a com- puter other than the one for which it was designed, elec- trolyte leakage, generation of heat, ignition or rupture may result.
Do Not Charge the Battery Using the Methods Other Than Indicated in This Manual
If the battery pack is not charged using one of the meth- ods indicated in this manual, electrolyte leakage, genera- tion of heat, ignition or rupture may result.
Do Not Throw the Battery Pack into a Fire or Expose It to Excessive heat
Generation of heat, ignition or rupture may result.
Avoid Extreme Heat (Near the Fire, in Direct Sunlight, for Example)
Electrolyte leakage, generation of heat, ignition or rupture may result.
Do Not Insert Sharp Objects into the Battery Pack, Expose It to Bumps or Shocks, Disassemble, or Mod- ify It
Electrolyte leakage, generation of heat, ignition or rupture may result.
Do Not Short the Positive (+) and Negative (-) Con- tacts
Generation of heat, ignition or rupture may result. Do not place the battery pack together with articles such as neck- laces or hairpins when carrying or storing.
Do Not Use This Computer with a Battery Pack Other Than the One Specified
Use only the specified battery pack
zDo not touch the terminals on the battery pack. The battery pack may no longer function properly if the contacts are dirty or damaged.
zDo not expose the battery pack to water, or allow it to become wet.
zIf the battery pack will not be used for a long period of time (a month or more), charge or discharge (use) the battery pack until the remaining battery level becomes 30% to 40% and store it in a cool, dry place.
zThis computer prevents overcharging of the battery by recharging only when the remaining power is less than approx. 95% of capacity.
zThe battery pack is not charged when the computer is 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 normal.
zRecharging will not commence if internal temperature of the battery pack is outside of the allowable tempera-
ture range (0 °C to 50 °C {32°F to 122°F}) (Î 
Ref- erence Manual “Battery Power”). Once the allowable range requirement is satisfied, charging begins auto- matically. 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 short- ened. Only use the computer within the allowable tem- perature range.
zThis computer has a high temperature mode function that prevents the degradation of the battery in high
temperature environments. (Î 
Reference Manual “Battery Power”) A level corresponding to a 100% charge for high temperature mode is approximately equivalent to an 80% charge level for normal tempera- ture mode.
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 package, briefcase, etc., it is recommended that it be placed in a plastic bag so that its contacts are protected.
zAlways power off the computer when it is not in use. Leaving the computer on when the AC adaptor is not connected will exhaust the remaining battery capacity.
