1 MB = 1,048,576 bytes

*2

A 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.

*3

1 GB = 1,000,000,000 bytes. Operating system or some application software will report as fewer GB.

*4

A 16,777,216 color display is achieved by using the dithering function.

*5

Display may be impossible using some connected external displays.

*6

Some devices cannot be used depending on the port type.

*7

Operation has been confirmed for Panasonic SD memory cards with up to 2 GB capacity. The transfer rate using the SD memory
card slot on this computer is 8 MB per second (this is a theoretical value, and differs from actual speeds). The transfer rate is 8
MB per second even if you use an SD memory card that supports high-speed transfer rates. Does not guarantee connection/
operation of all SD devices. Does not support MultiMedia card. Do not insert MultiMedia card.

*8

Only a RAM module designed for DDR2 (PC2-3200) can be added (Panasonic : CF-BAV0256U / CF-BAV0512U).
JEDEC standard 214 pin Micro DIMM cannot be used. PC2100 / PC2700 172 pin Micro DIMM cannot be used.

*9

Does not guarantee operation of all USB-compatible peripherals.

<Only for North America>
The AC adaptor is compatible with power sources up to 240 V AC adaptor. This computer is supplied with a 125 V AC compatible AC cord.

*11

Varies depending on the usage conditions, CPU speed, etc. Measured value when the power saving function on the USB2.0 USB
Root Hub is set to on. (At the time of purchase, the power saving function is set to off. 
When Economy Mode (ECO) is enabled, the operating time becomes approximately 20% shorter than when it is disabled.

*12

Measured using BatteryMark™ Version 4.0.1 (LCD brightness : Maximum - Minimum).

*13

Measured using MobileMark™ 2002 (LCD brightness : 60 cd/m2).

*14

Varies depending on the usage conditions, CPU speed, etc.
It may take a long time to charge a fully discharged battery.

*15

Approx. 1.5 W when the battery pack is fully charged (or not being charged) and the computer is off.

*16

Rated power consumption.

*17

Average value. May differ depending on models.

*18

Operations of this computer are not guaranteed except for the pre-installed OS.

*19

The Product Recovery DVD-ROM is required.

For information on TPM, input [c:\util\drivers\tpm\README.pdf] in [start] - [Run] and refer to the installation manual of “Trusted
Platform Module (TPM)”. You need to install Infineon TPM Professional Package to use TPM.
