Managing Power

    While your notebook is running on battery power, you should manage power consumption to get the most use out of the battery. This chapter shows you how to:

Check and recharge the battery
Change batteries
Extend the life of the battery by conserving battery power and using alternate power sources
Change power-saving settings

Monitoring the battery charge

    Closely monitor the battery charge. When the battery charge gets low, change the battery or connect to AC power immediately to prevent losing any unsaved work.

    Monitor the battery charge by:

Positioning the cursor over the power cord icon or battery icon in the taskbar. A battery status window opens. Move the cursor away from the icon to close the window.
Removing the main battery and optional second battery, then pressing the battery meter buttons. The battery meter lights indicate the percentage of battery charge remaining.
Waiting for a Low Battery warning message to appear.

    If your battery charge indicators display what looks like an inaccurate charge, you may need to recalibrate the battery. For more information, see "Recalibrating the battery".

Recharging the battery

    Both the main and the optional secondary batteries recharge while they are installed and your notebook is connected to AC power. While the batteries are recharging, the battery charge indicator becomes orange and the battery icon in the taskbar has a lightning bolt.

Recalibrating the battery

    If your notebook unexpectedly goes into Standby mode while you are using it but the battery charge is not low, you may need to recalibrate your battery. You should also recalibrate the battery once a year to maintain the accuracy of the battery gauge.

To recalibrate the battery:

    1. Connect the AC adapter, then turn on your notebook.

    2. As soon as it starts and you see a startup screen, press F2. The BIOS Setup program opens.

    3. Open the Advanced menu.

    4. Highlight Battery Auto Learning, then select Enabled by pressing the spacebar.

    5. Open the Exit menu, then highlight Exit Saving Changes and press Enter.

    6. Select Yes, then press Enter.
      The battery learning process begins and a screen opens showing you the progress. The entire process will take several hours.

Important

Do not interrupt the battery recalibration process. If recalibration is interrupted, you must start the process over again.

      When the recalibration is done, the message "Press [Esc] key to exit" appears.
    1. Press Esc . The battery meter now displays the accurate battery charge.
      If the battery meters do not show an accurate charge, contact Gateway Technical Support.

       

Changing batteries

    Your notebook must be turned off while changing the batteries.

Extending battery life

Conserving battery power

    While using the battery to power your notebook, conserve power by:

Dimming the display as low as is comfortable.
Removing PC Cards when you do not need them. Many PC Cards use a small amount of power while inserted, even if they are not being used.
Modifying the Power Management settings for maximum power savings. For more information, see "Changing power settings".
Closing the display panel to turn off the display while you are not using your notebook. The display stays off until you open the panel again.
Using Hibernate mode for maximum power savings while the notebook is not in use. For more information, see To activate Hibernate mode:.
Using the CD/DVD drive only when necessary. CD/DVD drives use a large amount of power.
Recharge the battery often, take an extra battery, and fully recharge the batteries before traveling. For more information, see "Recharging the battery" and "Changing batteries".

Using alternate power sources

    To extend battery life, use alternate power sources whenever possible.

If traveling internationally, take electrical adapters. Save the battery for times when you cannot use a power adapter. If you plan on taking your AC power adapter, also take a single-plug power surge protector.
If you will have access to an EmPowerTM in-flight power receptacle or an automobile cigarette lighter, use an airplane/automobile power adapter. Save the battery for times when you cannot use a power adapter.
To find AC power outlets in airports, look for them next to support pillars, in large areas such as boarding gates, and under banks of telephones.

Changing power modes

    You can use the following power modes to lengthen the life of your notebook's battery:

Standby - while your notebook is on standby, it switches to a low power state where devices, such as the LCD screen and drives, turn off.
Hibernate - (also called save to disk) writes all current memory (RAM) information to the hard drive, then turns your notebook completely off. The next time you turn on the notebook, it reads the memory information from the hard drive and opens the programs and documents that were open when you activated Hibernate. For more information on using Hibernate mode, see "To activate Hibernate mode:".

Using Standby mode

    Always save your work before using Standby mode. When in Standby, your computer reduces or turns off the power to most devices except memory. However, the information in the memory is not saved to the hard drive. If power is interrupted, the information is lost.

    When in Hibernate mode, your computer saves all memory information to the hard drive, then turns the power completely off.
