Battery types
The computer has three types of batteries:
❑Battery packs  – main and secondary (option)
❑Real Time Clock (RTC) battery
Main battery
When the AC power cord is not connected, the computer’s main power source is a
removable lithium ion battery pack, also referred to in this manual as the main
battery. You can purchase additional battery packs for extended use of the computer
away from an AC power source.
CAUTION: The battery pack is a lithium ion battery, which can explode
if not properly replaced, used, handled or disposed of. Dispose of the
battery as required by local ordinances or regulations. Use only batteries
recommended by TOSHIBA as replacements.
The main battery recharges the RTC batteries. The main battery maintains the state
of the computer when you enable Resume.
CAUTION: When the computer is powered off in Resume mode, and the
AC adaptor in not connected, the main battery pack and optional
secondary battery pack supply power to maintain data and programs in
memory. If the battery pack(s) is completely discharged, Resume does not
function and the computer loses all data in memory.
The following message appears when you turn on the power:
WARNING: RESUME FAILURE.
PRESS ANY KEY TO CONTINUE.

ODESSecondary battery (option)
An optional secondary battery can be installed in the Slim Select Bay to increase
your battery operating time. Note the caution on Resume mode in the previous
section Main battery.
CAUTION: The secondary battery pack is a lithium ion battery, which
can explode if not properly replaced, used, handled or disposed of.
Dispose of the battery as required by local ordinances or regulations. Use
only batteries recommended by TOSHIBA as replacements.
Real time clock battery
The Real Time Clock (RTC) battery provides power for the internal real time clock
and calendar. It also maintains the system configuration.
If the RTC battery becomes completely discharged, the system loses this data and
the real time clock and calendar stop working. The following message appears
when you turn on the power:
*** Bad RTC battery ***
Check system. Then press [F1] key . . . . . .
CAUTION: The computer’s RTC battery is a lithium ion battery and
should be replaced only by your dealer or by a TOSHIBA service
representative. The battery can explode if not properly replaced, used,
handled or disposed of. Dispose of the battery as required by local
ordinances or regulations.

Care and use of the battery pack
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.
Safety precautions
1. Be very careful not to short-circuit the battery pack. Contacting both terminals
with a metal object can cause injury, fire or damage to the battery pack.
2. Do not overcharge, reverse charge, mutilate or disassemble the battery pack.
Any one of those actions could release toxic materials, hydrogen and/or
oxygen or other electrolytic substances or cause an increase in the battery
pack’s surface temperature.
3. Do not expose the battery pack to fire; the battery pack could explode.
4. Battery packs contain toxic substances. Do not dispose of them with ordinary
trash. Dispose of battery packs only in accordance with local ordinances.
Always cover the metal terminals with insulating tape to avoid short circuits.
5. If the battery pack has leaked or been vented, it should be replaced
immediately. Use protective gloves when handling a damaged battery pack.
6. When it becomes necessary to replace the battery pack, it must be replaced
only by an identical battery pack from the same manufacturer.
7. Do not expose the battery pack terminals to any metal object other than the
computer contacts. Wrap it or place it in a plastic bag when transporting it.
8. When you install the battery pack, you should hear a click when it is seated
properly.
9. Charge the battery pack only in the computer or in a battery pack charger
designated as an approved option.
10. Reverse polarity should be avoided with all battery packs. The battery pack is
designed so that it cannot be installed in reverse polarity.

ODESCharging the batteries
When the power in the battery pack becomes low, the Battery indicator flashes
orange indicating that only a few minutes of battery power remain. If you continue
to use the computer while the Battery
 indicator flashes, the computer enables
Resume mode (so you don’t lose data) and automatically turns off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the AC
adaptor to the DC IN socket and plug the other end into a working outlet.
The Battery indicator glows orange when the battery is being charged.
CAUTION: Use only the computer connected to an AC power source or
the optional TOSHIBA Battery charger to charge the battery pack. Do not
attempt to charge the battery pack with any other charger.
Time
The following table shows the approximate time required to fully charge a dis-
charged battery.
Charging time (hours)
Battery type Power on Power off
Main battery pack 3.0 to 9.0 or longer 2.5
Secondary battery pack 3.0 to 7.5 or longer 2.5
RTC battery 8Doesn’t charge
Battery charging notice
The battery may not charge right away under the following conditions:
❑The battery is extremely hot or cold. If the battery is extremely hot, it might
not charge at all. Also, to ensure the battery charges to its full capacity, charge
the battery at room temperature of 10° to 30°C (50° to 88°F).
❑The battery is nearly completely discharged. Leave the AC adaptor connected
for a few minutes and the battery should begin charging.

  6-9 The Battery indicator may show a rapid decrease in battery operating time when
you try to charge a battery under the following conditions:
❑The battery has not been used for a long time.
❑The battery has completely discharged and been left in the computer for a long
time.
❑A cool battery is installed in a warm computer.
In such case, follow the steps below.
1. Fully discharge the battery by leaving it in the computer with the power on
until the power automatically shuts off.
2. Plug in the AC adaptor.
3. Charge the battery until the Battery indicator glows green.
Repeat the steps two or three times until the battery recovers normal capacity.
Monitoring battery capacity
Remaining battery power can be monitored in the Power Save Modes window in
Power Saver of Windows.
NOTES:1. Wait at least 16 seconds after turning on the computer before
trying to monitor the remaining operating time. The computer
needs this time to check the battery’s remaining capacity and
to calculate the remaining operating time, based on the
current power consumption rate and remaining battery
capacity. The actual remaining operating time may differ
slightly from the calculated time.
2. With repeated discharges and recharges, the battery’s
capacity will gradually decrease. Therefore, an often
used, older battery will not operate for as long as a new
battery even when both are fully charged. In this case,
Power Saver Utility will indicate a 100% charge for both
the old and new battery, but the displayed estimated time
remaining will be shorter for the older battery.
