    							With repeated discharges and recharges, the battery's capacity will
    gradually decrease. In view of this it will be noted that an often used,
    older battery will not operate for as long as a new battery even when
    both are fully charged.
    Maximizing battery operating time
    A battery's usefulness depends on how long it can supply power on asingle charge, while how long the charge lasts in a battery depends on:
    Processor speed
    Screen brightness
    System Sleep Mode
    System Hibernation Mode
    Display power off period
    Hard Disk Drive power off period
    How often and for how long you use the Hard Disk Drive and external
    disk drives, for example, optical disc.
    How much charge the battery contained to begin with.
    How you use optional devices, such as a USB device, to which the battery supplies power.
    Whether you enable Sleep Mode, which can conserve battery power ifyou are frequently turning the computer off and on.
    Where you store your programs and data.
    Whether you close the display panel when you are not using thekeyboard - closing the display saves power.
    The environmental temperature - operating time decreases at low
    temperatures.
    Whether you enable Sleep and Charge function.
    Batteries exhausted time When you turn off the power of your computer with batteries fully charged,
    the batteries will be exhausted within the following approximate period.

    Extending battery life
    To maximize the life of your battery packs:
    User's Manual 4-22 
    						
    							At least once a month, disconnect the computer from a power source andoperate it on battery power until the battery pack fully discharges. Before doing so, follow the steps as detailed below.1. Turn off the computer's power.2. Disconnect the AC adaptor and turn on the computer's power - if it
    does not turn on then go to Step 4.3. Operate the computer on battery power for five minutes. If you find that the battery pack has at least five minutes of operating time,continue operating until the battery pack is fully discharged, however, if
    the  DC IN/Battery  indicator flashes or there is some other warning to
    indicate a low battery condition, go to Step 4.4. Connect the AC adaptor to the DC IN 19V jack of the computer, and to a wall outlet that is supplying power. The  DC IN/Battery indicator
    should glow amber to indicate that the battery pack is being charged, however, in the event that  DC IN/Battery indicator does not glow this
    indicates that power is not being supplied - check the connections for
    the AC adaptor and the power cord.5. Charge the battery pack until the  DC IN/Battery indicator glows
    white.
    LAN
    The computer has built-in support for Ethernet LAN (10 megabits per
    second, 10BASE-T), Fast Ethernet LAN (100 megabits per second, 100BASE-TX) or Gigabit Ethernet LAN (1000 megabits per second,
    1000BASE-T).
    This section describes how to connect/disconnect to a LAN.
    The Wake-up on LAN function consumes power even when the
    system is off. Leave the AC adaptor connected while using this feature.
    The Link speed (10/100/1000 megabits per second) changes
    automatically depending on the network conditions (connected device, cable or noise and so on).
    LAN cable types
    The computer must be configured properly before connecting to a LAN.Logging onto a LAN using the computer’s default settings could cause amalfunction in LAN operation. Check with your LAN administrator regarding
    set-up procedures.User's Manual 4-23 
    						
    							If you are using Gigabit Ethernet LAN (1000 megabits per second,
    1000BASE-T), be sure to connect with a CAT5e cable or higher. You cannot use a CAT3 or CAT5 cable.
    If you are using Fast Ethernet LAN (100 megabits per second, 100BASE-
    TX), be sure to connect with a CAT5 cable or higher. You cannot use a
    CAT3 cable.
    If you are using Ethernet LAN (10 megabits per second, 10BASE-T), you
    can connect with a CAT3 or higher cable.
    Connecting the LAN cable To connect the LAN cable, follow the steps as detailed below:Connect the AC adaptor before connecting the LAN cable. The ACadaptor must remain connected during LAN use. If you disconnect the AC Adaptor while the computer is accessing a LAN, the system may
    hang up.
    Do not connect any other cable to the LAN jack except the LAN cable.
    Otherwise, malfunctions or damage may occur.
    Do not connect any power supplying device to the LAN cable that is
    connected to the LAN jack. Otherwise, malfunctions or damage may occur.
    1. Turn off the power to all external devices connected to the computer.
    2. Plug one end of the cable into the LAN jack. Press gently until you hear the latch click into place. Figure 4-5 Connecting the LAN cable
    1. LAN jack2. LAN cable
    3. Plug the other end of the cable into a LAN hub connector or router.
    Check with your LAN administrator and hardware or software vendorbefore using or configuring a network connection.
    Memory media The computer is equipped with a memory media slot that canaccommodate some kinds of memory media with various memory
    capacities so that you can easily transfer data from devices, such as digital cameras and Personal Digital Assistants.
    User's Manual 4-2421  
    						
    							Keep foreign objects out of the memory media slot. Never allow metal
    objects, such as screws, staples and paper clips, to enter the computer or Keyboard. Foreign metal objects can create a short circuit, which cancause computer damage and fire, possibly resulting in serious injury.Please note that an adaptor is required to use miniSD/microSD Card.
    Please note that not all memory media have been tested and verifiedto work correctly. Therefore, it is not possible to guarantee that allmemory media will operate properly.

    microSD card  MultiMediaCard (MMC)  
    Points to note about the memory media card
    SD/SDHC/SDXC memory cards comply with SDMI (Secure Digital MusicInitiative), which is a technology adopted to prevent unlawful copy or
    playback of digital music. For this reason, you cannot copy or playback
    protected material on another computer or other device, and you may not
    reproduce any copyrighted material except for your personal enjoyment.
    Below is a simple explanation for distinguishing SD memory cards from SDHC memory cards and SDXC memory cards.
    SD, SDHC and SDXC memory cards appear the same externally.
    However, the logo on memory cards is different, so pay careful
    attention to the logo when purchasing.
    The SD memory card logo is ().
    The SDHC memory card logo is ().
    The SDXC memory card logo is ().
    The maximum capacity of SD memory cards is 2GB. The maximum
    capacity of SDHC memory cards is 32GB. The maximum capacity of
    SDXC memory cards is 128GB.
    User's Manual 4-25       
    						
    							Memory media formatNew media cards are formatted according to specific standards. If you wish
    to reformat a media card, be sure to do so with a device that uses media cards.
    Formatting a memory media card
    Memory media cards are sold already formatted in conformity to specific
    standards. If you reformat a memory card, be sure to reformat it with a
    device such as digital camera or digital audio player that uses the memory
    cards, not with the format command provided within Windows.
    Should you need to format all areas of the memory card, including the
    protected area, you will need to obtain an appropriate application that applies the copy protection system.
    Media care
    Observe the following precautions when handling the card.
    Do not twist or bend cards.
    Do not expose cards to liquids or store in humid areas or lay media
    close to containers of liquid.
    Do not touch the metal part of a card or expose it to liquids or let it get
    dirty.
    After using card, return it to its case.
    The card is designed so that it can be inserted only one way. Do not try to force the card into the slot.
    Do not leave a card partially inserted in the slot. Press the card untilyou hear it click into place.
    Set the write-protect switch to the lock position, if you do not want to
    record data.
    Memory cards have a limited lifespan, so it is important to backup
    important data.
    Do not write to a card if the battery power is low. Low power could
    affect writing accuracy.
    Do not remove a card while read/write is in progress.
    For more details on using memory cards, see manuals accompanying the
    cards.
    About the write-protect feature
    Memory media cards have a write-protect function.
