							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 design applications

CPU performance may also vary from specifications due to design configuration.
Under some conditions, your computer product may 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.

64-Bit Computing
64-bit processors are designed to take advantage of 32 and 64 bit
computing.
64-bit computing requires that the following hardware and software requirements are met:
64-bit Operating System
64-bit CPU, Chipset and BIOS (Basic Input/Output System)
64-bit Device drivers
64-bit applications
Certain 32-bit device drivers and/or applications may not be compatible with a 64-bit CPU/operating system and therefore may not functionproperly.
Memory (Main System) Part of the main system memory may be used by the graphics system forgraphics performance and therefore reduce the amount of main system memory available for other computing activities. The amount of mainsystem memory allocated to support graphics may 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 memorymight be displayed as approximately 3 GB only (depending on thecomputer’s hardware specifications).
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, etc.) 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 a technical limitation that the overlapped memory is not available to the operating system. Eventhough some tools might display the actual physical memory built into your
computer, the memory available to the operating system will still be
approximately 3 GB only.
Computers configured with a 64-bit operating system can address 4 GB or
more of system memory.
Battery Life Battery life may 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 are
achieved on select models and configurations tested by TOSHIBA at the
time of publication. Recharge time varies depending on usage. Battery may
not charge while computer is consuming full power.
After going through many charge and discharge cycles, the battery will lose
its ability to perform at maximum capacity and will need to be replaced. This is a normal phenomenon for all batteries. To purchase a new battery
pack, see the 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 may 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 will dim when the computer is operated on battery power and you
may not be able to increase the brightness of the screen.

							Graphics Processing Unit (GPU)Graphics processing unit (GPU) performance may vary depending on
product model, design configuration, applications, power management settings and features utilized. GPU performance is only optimized when
operating in AC power mode and may 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 will vary depending on system memory size and other factors.
Wireless LAN The transmission speed over the wireless LAN and the distance over whichwireless LAN can reach may vary depending on surrounding
electromagnetic environment, obstacles, access point design and
configuration, and client design and software/hardware configurations.
The actual transmission speed will be lower than the theoretical maximum
speed.
Copy Protection Applicable copy protection standards included in certain media may
prevent or limit recording or viewing of the media.
