use of computer at temperatures outside the range of 5°C to 30°C (41°F to 86° F) or >25°C (77°F) at high altitude (all temperature references are
approximate and may vary depending on the specific computer model – please visit the Toshiba website at www.pcsupport.toshiba.com for details).
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. Use your
computer product only under recommended conditions. Read additional restrictions under “Environmental Conditions” in your product “Detailed Specs.” Contact Toshiba Technical
Service and Support for more information.

Wireless-N.
The wireless adapter is based on a draft release version of the IEEE 802.11n specification, and may not be compatible with, or support all features (e.g., security) of,
certain Wi-Fi® equipment
.
5
Memory (Main System)
. Part of the main system memory may 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 may vary depending on the graphics system, applications
utilized, system memory size and other factors. For PC's configured with 4 GB of system memory, the full system memory space for computing activities will be considerably less
and will vary by model and system configuration.
6
Storage Drive (Capacity
)
Computer (Internal) HDD Capacity. One 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 computer
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.
7
Optical Drive
. Due to manufacturing and quality variations in third party optical media (e.g., CD or DVD) or optical media players/recorders, in certain cases, your Toshiba optical
drive may not record on certain optical media that bear the applicable logo, or playback optical media recorded by other PCs or optical media recorders. Additionally, certain optical
media recorded on your optical drive may not playback or operate properly on other PCs or optical media players. These problems are not due to any defect in your Toshiba PC or
optical drive. Please refer to your PC's product specification for listing of specific format compatibilities.
Recording or viewing of certain optical media may be limited or prevented in accordance with applicable copy protection standards.
8
Display
. Small bright dots may appear on your screen display when you turn on your PC. Your display contains an extremely large number of thin-film transistors (TFT) and is
manufactured using high-precision technology. Any small bright dots that may appear on your display are an intrinsic characteristic of the TFT manufacturing technology. Over a
period of time, and depending on the usage of the computer, the brightness of the screen will deteriorate. This is also an intrinsic characteristic of the screen technology.
When the computer is operated on battery power, the screen with dim and you may not be able to increase the brightness of the screen while on battery power.
9
Graphics (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.
10
Wireless
. Wireless connectivity and some features may require you to purchase additional software, external hardware or services. Availability of public wireless LAN access
points may be limited. The transmission speed over the wireless LAN and the distance over which wireless 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. To use the Atheros SuperAG™ or SuperG™ wireless function, if available, your client and access point must support the corresponding feature.
Performance of these functions may vary depending on the format of data transmitted.
11
Wireless-N.
The wireless adapter is based on a draft release version of the IEEE 802.11n specification, and may not be compatible with, or support all features (e.g., security) of,
certain Wi-Fi® equipment
.
12
USB Sleep & Charge.
The "USB Sleep & Charge function" may not work with certain external devices even if they are compliant with the USB specification. In those cases, turn
the power of the computer ON to charge the device.
13
Weight
. Weight may vary depending on product configuration, vendor components, manufacturing variability and options selected.
14
Battery Life
. 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. Published battery life numbers are achieved on select models and configurations
tested by Toshiba at the time of publication. See “Detailed Specs” for specific battery measurement test. Recharge time varies depending on usage. Battery may not charge while
computer 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 purchase a new battery pack, see the accessories information that shipped with your computer or visit the Toshiba web site at

Software
. Some software may differ from its retail version (if available), and may not include user manuals or all program functionality.
Certain Microsoft® software products (including Microsoft Office Small Business Accounting if applicable) included with this computer may use technological measures for copy
protection. IN SUCH EVENT, YOU WILL NOT BE ABLE TO USE THE PRODUCT IF YOU DO NOT FULLY COMPLY WITH THE PRODUCT ACTIVATION
PROCEDURES. Product activation procedures and Microsoft’s privacy policy will be detailed during initial launch of the product, or upon certain reinstallations of the software
products or reconfigurations of the computer, and may be completed by Internet or telephone (toll charges may apply).
Internet access is required to enable certain functionality of certain Microsoft products(including Microsoft Office Small Business Accounting 2006) which may be included with this computer.
The Microsoft Office 2007 60-Day Trial software (if applicable) is intended for evaluation purposes only. You must activate the software before you can use it. Product activation
procedures will be detailed during initial launch of the software; activation requires Internet access. This software has an expiration date of 60 days from date of first use, at which
time the software will operate under reduced-functionality mode, limiting end-user options and operations. The Microsoft Office 2007 60-Day Trial software is distributed without
charge to the End User Customer but if the End User wants to continue to use such product after the trial period, then the End User Customer will have to pay a fee for the
perpetual version of such Office Product.
