Charging batteries
lose its charge completely, especially if you have had the computer
turned off for a long time.
To recharge the RTC battery, plug in the computer and leave it
turned off for at least 24 hours.
TECHNICAL NOTE: It is seldom necessary to charge the RTC
battery because it charges while the computer is on. If the
RTC battery is low, the real-time clock and calendar become
slow or stop working.
When Hibernation mode is enabled and the RTC battery is
completely discharged, a warning prompts you to reset the
real-time clock.
Using a battery charger
You can purchase an optional battery charger that recharges
lithium ion battery packs without requiring the use of your
computer.
Use the battery charger to charge the optional high-capacity
battery, and to charge spare main battery packs.
CAUTION: Avoid leaving batteries in the battery charger for
more than a week at a time. Doing so may reduce the
potential charge of the battery.
Use only battery chargers designed to work with your
computer and its batteries. You can order a Toshiba battery
charger through the accessories information sheet or
