use of computer at temperatures outside the range of 5°C to 30°C
(41–86°F) or >25°C (77°F) at high altitude (all temperature references
are approximate and might vary depending on the specific computer
model - contact TOSHIBA support for details).
CPU performance might also vary from specifications due to design
configuration.
Under some conditions, your computer product might automatically
shutdown. 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
Certain 32-bit device drivers and/or applications might not be compatible
with a 64-bit CPU/operating system and therefore might not function
properly.
Memory (Main System)
Part of the main system memory might 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 might vary depending on the
graphics system, applications utilized, system memory size, and other
factors.
If your computer is configured with more than 3 GB memory, the memory
might be displayed as approximately 3 GB only (depending on the
hardware specifications of the computer).
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, and so on) 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 is still approximately 3 GB only.
Computers configured with a 64-bit operating system can address 4 GB or
more of system memory.
