Toshiba lx810 Laptop User Manual


 
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 refer to your computer documentation or 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. For optimum
performance, use your computer product only under recommended
conditions. Read additional restrictions in your product documentation.

64-Bit Computing
64-bit processors are designed to take advantage of 32 and 64 bit
computing.
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.
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.
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
