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 device drivers and/or applications may not be compatible with a 64-bit CPU and therefore may not function properly. See "Detailed Specs" for more information.

Processor (Central Processing Unit)
. Also see
64-Bit Computing
Legal Footnote, if applicable.
CPU performance in your computer product may vary from specifications under the following conditions:
1.
use of certain external peripheral products
2.
use of battery power instead of AC power
3.
use of certain multimedia, computer generated graphics or video applications
4.
use of standard telephone lines or low speed network connections
5.
use of complex modeling software, such as high end computer aided design applications
6.
use of several applications or functionalities simultaneously
7.
use of computer in areas with low air pressure (high altitude >1,000 meters or >3,280 feet above sea level)
8.
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.

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.
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. Computers configured with a 32-bit operating system can address up to 3GB of system memory. Only computers configured with a
64-bit operating system can address 4 GB or more of system memory.
6
Storage Drive
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.
