The size ofthe Video Memory cannot be set by the user.The size of Video memory is allotted depending on the oper-ating system.*5 1 GB = 1,000,000,000 bytes. Your operating system or someapplication software will report as fewer GB.*6 Data transfer speeds indicate values measured byPanasonic Corporation. The data transfer rate of DVD per 1Xspeed is 1,350 KB/s. The data transfer rate of CD per 1Xspeed is 150 KB/s.*7 Performance of CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RDL, DVD-RW, +R, +R DL, and +RW cannot be guaranteeddepending on writing status and recording format. Also,some data cannot be played back depending on the disc,settings, and environment being used.Does not support writing to DVD-R DL/+R DL (dual layerdiscs) and Ultra-Speed CD-RW. Does not support 2.6 GBDVD-RAM.*8 If an unbalanced disc (e.g., a disc with which the balance has beendisplaced from the center) is inserted, the speed may becomeslower if there are large vibrations while the disc is rotating.*9 Depending on the disc, the writing speed may become slower.*10 Only non-cartridge type or removable cartridge type can be used.*11 DVD-R is compatible with 4.7 GB (for General) playback.DVD-R (for Authoring) playback is compatible with discsrecorded using Disc-at-Once recording.*12 A 16,777,216 color display is achieved by using the ditheringfunction.*13 Display may be impossible using some connected externaldisplays.*14 Only for model with wireless LAN.*15 Only for model with Bluetooth.*16 Some devices cannot be used depending on the port type.*17 Only for model with modem.*18 Only for model that supports TPM.For information on TPM, click (Start) andinput “c:\util\drivers\tpm\README.pdf” in [Search programsand files] and press Enter, and refer to the InstallationManual of “Trusted Platform Module (TPM)”.For information on TPM, click [start] - [Run]and input “c:\util\drivers\tpm\README.pdf”, and refer to theInstallation Manual of “Trusted Platform Module (TPM)”.*19 This slot is not compatible with the UHS-I high speed trans-fer. Operation has been tested and confirmed using Pana-sonic SD Memory Card with a capacity of up to 2 GB,Panasonic SDHC Memory Card with a capacity of up to32 GB, and Panasonic SDXC Memory Cardwith a capacity of up to 64 GB. Operation on other SD equip-ment is not guaranteed.*20 Does not guarantee operation of all USB-compatible peripherals.*21 Use a condenser-stereo microphone.*22 Port Replicator(optional): CF-VEBU08U and CF- VEBF81W canbe used.*23 The AC adaptor is compatible with power sources up to240 V AC adaptor. This computer is supplied with a 125 VAC compatible AC cord. 20-M-1-1*24 Measured using MobileMark™ 2007 (LCD brightness :60 cd/m2).Varies depending on the usage conditions, or when anoptional device is attached.When Economy Mode (ECO) is enabled, the operating timebecomes approximately 20% shorter than when it is disabled.*25 When Economy Mode (ECO) is enabled, the charging timebecomes approx. 5.0 hours (Power on/off). Varies dependingon the usage conditions, CPU speed, etc.It may take a long time to charge a fully discharged battery.*26 Approx. 0.9 W when the battery pack is fully charged (or notbeing charged) and the computer is off. V AC>Even when the AC adaptor is not connected to the computer,power is consumed (Max. 0.4 W) simply by having the ACadaptor plugged into an AC outlet.*27 Rated power consumption. 23-E-1*28 Average value. May differ depending on models.*29 Operations of this computer are not guaranteed except forthe pre-installed OS and the installed OS by using the Prod-uct Recovery DVD-ROM (included).Some parts of the software in the Product Recovery DVD-ROM may not be installed depending on a model.*30 Must be installed before use.*31 Only for model with fingerprint reader.Must be installed before use.*32 The graphics accelerator of this computer supports up toDirectX 10.*33 Only for model that supports TPM.Must be installed before use.*34 Must be installed before use.*35 The Product Recovery DVD-ROM is required.*36 These are speeds specified in IEEE802.11a+b+g+n stan-dards.
