*11MB  = 1,048,576 bytes*2You can physically expand the memory up to 4096  MB, but 
the total amount of usable memory available will be less 
depending on the actual system configuration.
*3A segment of the main memory is allotted automatically 
depending on the computer’s operating status. The size of 
the Video Memory cannot be set by the user.
*41 GB  = 1,000,000,000 bytes. Your operating system or some 
application software will report as fewer  GB.
*5A 16,777,216 color display is achieved by using the dithering 
function.
*6Maximum resolution depends on the specifications of the 
external display.
*9For information on TPM, click [start] - [Run] and input 
“c:\util\drivers	pm\README.pdf”, and refer to the Installation 
Manual of “Trusted Platform Module (TPM)”.
*10Operation has been tested  and confirmed using Panasonic 
SD Memory Cards with a capacity of up to 2 GB.
Operation on other SD equipment is not guaranteed.
This computer is not compatible with MultiMediaCards or 
SDHC Memory Cards. Do not insert these kinds of cards.
*11Theoretical value and not the actual speed. The transfer rate 
does not become higher even if you use a card that supports 
the higher transfer rate.
*12Only for model with Smart Card slot*13
The AC adaptor is compatible with power sources up to 
240 V AC adaptor. The computer is supplied with a 125  V 
AC compatible AC cord.
