The RTC battery does not charge while the computer is turned off even if
the AC adapter is attached.
Care and use of the battery pack
The battery pack is a vital component of portable computing. Taking proper
care of it will help ensure longer operating time on battery power as well as
a longer life for your battery pack. Follow the instructions in this section
carefully to ensure safe operation and maximum performance.
Refer to the enclosed Instruction Manual for Safety & Comfort for detailed
precautions and handling instructions.
Make sure the battery is securely installed in the computer before
attempting to charge the battery pack. Improper installation could
generate smoke or fire, or cause the battery pack to rupture.
Keep the battery pack out of reach of infants and children. It can cause
injury.
Use only battery packs recommended by TOSHIBA as replacements.
Charge the battery pack only in an ambient temperature between 5 and
35 degrees Celsius. Otherwise, the electrolyte solution might leak,
battery pack performance might deteriorate and the battery life might
be shortened.
Never install or remove the battery pack without first turning off the
power and disconnecting the AC adaptor. Never remove the battery
pack while the computer is in Standby Mode. Data will be lost.
Never remove the battery pack while the Wake-up on LAN function is
enabled. Data will be lost. Before you remove a battery pack, disable
the Wake-up on LAN function.
Never remove the battery pack while the Wake-up on Wireless LAN
function is enabled. Data will be lost. Before you remove a battery
pack, disable the Wake-up on Wireless LAN function.
To ensure the battery pack maintains maximum capacity, operate the
computer on battery power once a week until the battery pack is fully
discharged. Refer to the section
for procedures. If the computer is continuously operated on AC power
for an extended period, more than a week, the battery might fail to
retain a charge. It might not function efficiently over the expected life of
the battery pack and the Battery indicator might not indicate a
low-battery condition.
After the battery pack is charged, avoid leaving the AC adaptor
connected and the computer turned off for more than a few hours at a
time. Continuing to charge a fully-charged battery pack can damage
the battery.
