HDD Drive Capacity and External HDD Capacity
*4
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 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
*5
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
will not be able to increase the brightness of the screen.
Graphics Processor Unit (GPU)
*6
Graphics processor 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
*7
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
