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.
Computers configured with a 32-bit operating system can address up to
approximately 3 GB of system memory.
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.
