Changing the main battery
If the battery is leaking or its case is cracked, put on 
protective gloves to handle it, and discard it immediately. 
Always dispose of used battery packs in compliance with 
all applicable laws and regulations. Put insulating tape, 
such as cellophane tape, on the electrode during 
transportation to avoid a possible short circuit, fire or 
electric shock. Failure to do so could possibly result in 
serious injury.
Inserting a charged battery
To insert a battery:
1Wipe the terminals of the charged battery with a clean 
cloth to ensure a good connection.
2Insert the charged battery into the slot until the latch 
clicks.
The battery pack has been designed so that you cannot 
install it with reverse polarity.
If the battery does not slide into the slot easily, move the 
battery release lock to the unlocked position and try 
again. Do not force the battery into position.

using the computer if you observe any of the following 
conditions:
❖Offensive or unusual odor
❖Excessive heat
❖Discoloration
❖Deformation, cracks, or leaks
❖Smoke
❖Other unusual events during use, such as 
abnormal sound
Do not expose the computer to fire. The battery could 
explode

Disposing of used batteries
Maintaining your battery
Fully discharging your battery pack will allow better accuracy 
of the battery meter.
To fully discharge your battery pack:
❖Periodically, disconnect the computer from a power 
source and operate it on battery power until the battery 
pack fully discharges.
❖If you have extra battery packs, rotate their use (for 
models with an accessible battery only).
❖If you will not be using the system for an extended 
period, more than one month, remove the battery pack 
(for models with an accessible battery only).
❖Store spare battery packs in a cool dry place out of 
direct sunlight (for models with an accessible battery 
only).
Disposing of used batteries
The life of a battery pack depends on usage. When the 
battery pack needs replacing, the main battery light flashes 
amber shortly after you have fully recharged the battery. 
You must discard a battery if it becomes damaged.
Never attempt to dispose of a battery pack by burning or 
by throwing it into a fire, and never allow exposure to a 
heating apparatus (e.g., microwave oven). Heat can 
cause a battery pack to explode and/or release caustic 
liquid, both which may possibly cause serious injury.
Always dispose of used battery packs in compliance with 
all applicable laws and regulations. Put insulating tape, 
such as cellophane tape, on the electrode during 
transportation to avoid a possible short circuit, fire or 
electric shock. Failure to do so could possibly result in 
serious injury.

Traveling tips
Always use the battery pack supplied as an accessory or 
an equivalent battery pack specified in the User's 
Manual. Other battery packs have different voltage and 
terminal polarities. Use of non-conforming battery packs 
could generate smoke or cause fire or rupture, possibly 
resulting in serious injury.
After repeated use, the batteries will finally lose their ability 
to hold a charge and you will need to replace them. Under 
certain applicable laws and regulations, it may be illegal to 
dispose of old batteries by placing them in the trash.
Please be kind to our shared environment. Check with your 
local government authority for details regarding where to 
recycle old batteries or how to dispose of them properly.
In addition, Toshiba’s recycling initiatives include recycling 
programs, events and consumer promotions. For details, 
please visit toshiba.com/recycle.
Toshiba is dedicated to preserving the environment by 
sponsoring 
Call2Recycle™, a program of the 
Rechargeable Battery Recycling Corporation, so you can 
easily recycle accessible rechargeable batteries. For more 
information and for free drop-off locations, visit
