This chapter covers all aspects of using your device while traveling.
Toshiba’s energy-saver design
Your device enters a low-power suspension mode when it is not being used, thereby conserving energy and saving money in the process. It has a number of other features that enhance its energy efficiency.
Many of these energy-saving features have been preset by
Toshiba. We recommend you leave these features active, allowing your device to operate at its maximum energy efficiency, so that you can use it for longer periods while traveling.
Running the device on battery power
The device contains a Lithium-Ion (Li-Ion) battery that provides power when you are away from an AC outlet. You can recharge it many times.

Battery Notice
Battery life rating is for comparison purposes only, and does not indicate the battery life that will be obtained by any individual user. Actual battery life may vary considerably from specifications depending on product model, configuration, applications, power management settings and features utilized, as well as the natural performance variations produced by the design of individual components.
The battery life rating is only achieved on the select models and configurations tested by Toshiba under the specific test settings at the time of publication and is not an estimate of a system’s battery life under any conditions other than the specific test settings.
Recharge time varies depending on usage. Battery may not charge while the device is consuming full power. After a period of time, the battery will lose its ability to perform at maximum capacity and will need to be replaced. This is normal for all batteries.
To ensure that the battery maintains its maximum capacity, operate the device on battery power at least once a month.
The Lithium-Ion battery has no memory effect so it is not necessary to let the battery fully discharge each time.
However, for better accuracy of the battery meter, it is helpful to fully discharge the battery periodically. Please see
“Maintaining your battery” on page 63
for procedures. If the device is continuously operated on AC power, either through an optional USB/AC adaptor or a port replicator (if applicable to your system), for an extended period (more than a month), the battery may fail to retain a charge. This may shorten the life of the battery, and may cause the battery meter to be inaccurate.

Power management
Your device ships with the power management options preset to a configuration that will provide the most stable operating environment and optimum system performance for both AC power and battery modes.
Changes to these settings may result in system performance or stability issues. Users who are not completely familiar with the power management component of the system should use the preset configuration. For assistance with setup changes, contact Toshiba’s Customer Support Center.
Charging the battery
If the device is leaking or its case is cracked, put on protective gloves to handle it.
NOTE Your device’s battery is not accessible to the user.
Your device contains a rechargeable battery that may need to be charged prior to use.
To use external power or to charge the battery you must attach an optional USB/AC adaptor. See
“Connecting to a power source” on page 36 .
To charge the device plug it into a power source.
NOTE Battery life and charge time may vary depending on the external conditions, or the applications and features used.
NOTE Please handle your device carefully to avoid scratching or damaging the surface.

Charging the battery
USB Charge —In “Sleep mode,” you can also charge your tablet, although more slowly, by connecting the USB power cable to the USB port on another computer. Please make sure your computer is turned ON while charging via USB. If your computer is turned OFF, depending on the computer’s specifications, the tablet battery may discharge. Toshiba recommends that you do not use your tablet while charging via USB as auto shut down may occur if the battery charge is too low.
Wall Outlet —The fastest way to charge your tablet is with an optional USB/AC adaptor plugged into a wall outlet.
Determining remaining battery power
NOTE Wait a few moments after turning on the device before trying to monitor the remaining battery power. The device needs this time to check the battery’s remaining capacity and perform its calculations.
Touch the power icon in the notification area. (See “Finding your way around the desktop” on page 67
for more information on the notification area.) The window displays the remaining battery power as a percentage.
With repeated discharges and recharges, the battery’s capacity gradually decreases. A frequently used older battery does not power the device for as long as a new battery, even when fully charged.
TECHNICAL NOTE: The device drains the battery faster at low temperatures. Check your remaining charge frequently if you are working in temperatures below 50 degrees Fahrenheit.
The device calculates the remaining battery charge based on your current rate of power use and other factors such as the age of the battery.
What to do when the battery runs low
When the battery run low you can:
❖
Plug the device into an external power source and recharge the battery via the Micro USB port. See
“Connecting to a power source” on page 36
❖
Save your work and turn off the device

If you do not manage to do either of these things before the battery completely runs out of power, the device automatically enters a power-saving state and turns itself off so that when you turn on the power again after connecting an external power source, you can continue where you left off.
Setting battery notifications
You can set two notifications. Each notification can be set to alert you when a specified percentage of remaining battery power has been reached. You can also set the device to enter Sleep mode or to completely shut down when the notification goes off.
To change the default notification settings:
1 While on the desktop, touch the Battery ( ) icon in the notification area.
A window appears displaying the power level of the battery.

2 Touch More power options .
The Power Options window appears.
3 Touch Change plan settings under the power plan to be customized.
The Edit Plan Settings window appears.
4 Touch Change advanced power settings .
The Advanced settings tab of the Power Options window appears.

6 Configure the alarm settings to suit your needs.
Conserving battery power
How long a fully charged battery lasts when you are using the device depends on a number of factors, such as:
❖ How the device is configured
❖ How much you use the internal storage drive or other optional devices
❖
Where you are working, since operating time decreases at low temperatures
There are various ways in which you can conserve power and extend the operating time of your battery:
❖
Enable Sleep (default setting is Enabled), which saves power when you turn off the device and turn it back on again
❖
Use the Windows ® power-saving option plans

Power-saving options control the way in which the device is configured. By using them, you can increase the length of time you can use the device before you need to recharge the battery.
You may set individual power-saving options to suit your own needs.
The following section describes how to choose or create a
Power Plan and explains the available power-saving option.

Safety precautions
Always immediately turn the power off and disconnect the power cable/cord plug from the plug socket and stop using the device 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 device to fire. The batteries could explode.
Do not turn on the device’s power again until an authorized
Toshiba service provider has checked it for safety.
Continued use could cause a fire or rupture possibly resulting in serious injury or device failure including but not limited to the loss of data.
Maintaining your battery
Fully discharging a battery will allow better accuracy of the battery meter.
To fully discharge your battery:
❖
Periodically, disconnect the device from a power source and operate it on battery power until the battery fully discharges.
Disposing of your device
Never attempt to dispose of a device 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 device to explode and/or release caustic liquid, both which may possibly cause serious injury.
Discard this device in accordance with applicable laws and regulations.
