If your computer is configured with more than 3 GB memory, the memory
might be displayed as approximately 3 GB only (depending on the
computer’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. Even
though 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.
