The computer's allowable operating temperature range is 5ºC
(41ºF) to 35ºC (95ºF). The duration of a battery's operation

When a spare battery pack is to be carried in a pocket or bag,
it is recommended that it be placed in a plastic bag so that its
contacts are protected.
The battery pack may become warm during recharging or
use. This is completely normal.
Although the battery has remaining capacity, the battery
indicator may light up red or emit a beep. This indicates a
significant rise in the temperature of the battery pack. This is
typically caused by the fact that the battery pack has been
delivering a high level of power because the computer has
been used with the display at the brightest setting and with
the power-saving function off. In this condition, if the
computer is left as is, it will automatically go off after about
three minutes have elapsed. Within that period, be sure to
connect the AC adapter or shut the computer OFF after saving
any open data (if necessary).
(To protect the battery pack from increases in temperature,
the brightness of the display automatically decreases, allow-
ing the temperature of the battery to drop.)
Always power off the computer when it is not in use. Leaving
the computer on when the AC adapter is not connected will
exhaust the remaining battery capacity.
If 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.
Mounting, Unmounting, and Charging
