							Changes or modifications not expressly approved by the party responsible
for compliance could void the user‘s authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will notoccur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correctthe interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
RF Exposure Information
This device is designed and manufactured not to exceed the emission
limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission for an uncontrolled environment.

Certain computer chassis are designed to accommodate all possible
configurations for an entire product series. Therefore, be aware that your selected model might not have all the features and specificationscorresponding to all of the icons or switches shown on the computer
chassis.
CPU Central Processing Unit (CPU) Performance Legal Footnotes.
CPU performance in your computer product might vary from specifications under the following conditions:
use of certain external peripheral products
use of battery power instead of AC power
use of certain multimedia, computer generated graphics or video
applications
use of standard telephone lines or low speed network connections
use of complex modeling software, such as high end computer aided

							use of several applications or functionalities simultaneously
use of computer in areas with low air pressure (high altitude >1,000
meters or >3,280 feet above sea level)
use of computer at temperatures outside the range of 5°C to 30°C
(41–86°F) or >25°C (77°F) at high altitude (all temperature references
are approximate and might vary depending on the specific computer

CPU performance might also vary from specifications due to design configuration.
Under some conditions, your computer product might automatically shut
down. This is a normal protective feature designed to reduce the risk of lost data or damage to the product when used outside recommended
conditions. To avoid risk of lost data, always make back-up copies of data by periodically storing it on an external storage medium. For optimum
performance, use your computer product only under recommended conditions. Read additional restrictions in your product documentation.
Contact TOSHIBA technical service and support, refer to  TOSHIBA support

64-Bit Computing
Certain 32-bit device drivers and/or applications might not be compatible with a 64-bit CPU/operating system and therefore might not functionproperly.
Memory (Main System) Part of the main system memory might be used by the graphics system for
graphics performance and therefore reduce the amount of main system memory available for other computing activities. The amount of main system memory allocated to support graphics might vary depending on thegraphics system, applications utilized, system memory size, and other
factors.
If your computer is configured with more than 3 GB memory, the memory might be displayed as approximately 3 GB only (depending on thehardware specifications of the computer).
This is correct because the operating system usually displays the available
memory instead of the physical memory (RAM) built into the computer.
Various system components (like the video adapter’s GPU and PCI
devices like Wireless LAN, and so on) require their own memory space.
Since a 32-bit operating system cannot address more than 4 GB of memory, these system resources overlap the physical memory. It is atechnical limitation that the overlapped memory is not available to theoperating system. Even though some tools might display the actualphysical memory built into your computer, the memory available to the
operating system is still approximately 3 GB only.
User's Manual 7-15 
						

							Computers configured with a 64-bit operating system can address 4 GB or
more of system memory.
Battery Life Battery life might vary considerably 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. Published battery life numbers areachieved on select models and configurations tested by TOSHIBA at thetime of publication. Recharge time varies depending on usage. Batterymight not charge while computer is consuming full power.
After going through many charge and discharge cycles, the battery loses its
ability to perform at maximum capacity and needs to be replaced. This is a normal phenomenon for all batteries. To purchase a new battery pack, seethe accessories information that is shipped with your computer.
Hard Disk Drive (HDD) Capacity 1 Gigabyte (GB) means 10 9
 = 1,000,000,000 bytes using powers of 10.
The computer operating system, however, reports storage capacity using
powers of 2 for the definition of 1 GB = 2 30
 = 1,073,741,824 bytes, and
therefore shows less storage capacity. Available storage capacity will also be less if the product includes one or more pre-installed operating systems,
such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity might vary.
LCD Over a period of time, and depending on the usage of the computer, the
brightness of the LCD screen will deteriorate. This is an intrinsic
characteristic of LCD technology.
Maximum brightness is only available when operating in AC power mode.
Screen dims when the computer is operated on battery power and you
might not be able to increase the brightness of the screen.
Graphics Processing Unit (GPU) Graphics processing unit (GPU) performance might vary depending on
product model, design configuration, applications, power management settings and features utilized. GPU performance is only optimized whenoperating in AC power mode and might decrease considerably when
operating in battery power mode.
Total Available Graphics Memory is the total of, as applicable, Dedicated
Video Memory, System Video Memory and Shared System Memory. Shared System Memory varies depending on system memory size and other factors.
