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 periodically to maintain the accuracy 
of the battery gauge.
To recalibrate the battery:
1Disconnect the AC adapter
2Turn on your notebook.
3As soon as it starts and you see a startup screen, press F2. The BIOS Setup 
utility opens.
4Open the Power menu.
5Highlight Smart Battery Calibration, then press ENTER. When prompted, start 
the recalibration program.
6After the battery has been fully discharged and your notebook has turned 
itself off, re-connect the AC adapter and fully recharge your battery. 
Recharging may take several hours. After the battery finishes recharging, 
the battery meter displays the accurate battery charge. If the battery meter 
does not show an accurate charge, contact Gateway Technical Support.
ImportantDo not interrupt the battery recalibration process. If 
recalibration is interrupted, you must start the process over 
again.

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” on page 155.

Closing the LCD 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 your notebook 
is not in use. For more information, see “Activating and using Hibernate 
mode” on page 159.

Using the DVD or recordable drive only when necessary. These 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” on page 149 and “Changing batteries” on page 151.
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 surge protector.

If you will have access to an EmPower™ 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 in Standby, it switches to a low power 
state where devices, such as the display 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 your notebook, it reads the memory 
information from the hard drive and opens the programs and documents 
that were open when you activated Hibernate mode. For more information 
on using Hibernate mode, see “Activating and using Hibernate mode” on 
page 159.
Using power saving modes
Always save your work before using Standby mode. In Standby mode, your 
notebook reduces or turns off the power to most devices except memory. 
However, the information in 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.
If your computer 
is......and you want to... ...then
