Monitoring the battery charge
Your new Gateway notebook is designed to provide an 
exceptional balance of performance and portability. Your 
notebook uses the latest chipset and mobile processor 
technologies to manage the processor speed and power 
consumption for a greater battery life experience. This design 
provides you with maximum performance when plugged into 
AC power balanced with optimized battery life when on 
battery power.
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. To monitor 
the battery charge:
Move the mouse pointer over the power cord icon  
or battery icon  in the taskbar. A message appears 
showing the remaining battery time and the current 
power plan.
Wait for a Low Battery warning message to appear.
Look at the battery charge status indicator.
If your battery charge indicator displays what looks like 
an inaccurate charge, you may need to recalibrate the 
battery.
Recharging the battery
The battery recharges while it is installed and your notebook 
is connected to AC power. While the battery recharges, the 
battery charge indicator turns on.Tip
For more information about the battery charge status indicator, 
see “Front” on page 6.
TipFor more information about recalibrating the battery, see 
“Recalibrating the battery” on page 70.

Changing the battery
To replace the battery:  
1If your notebook is on and is connected to AC power, go 
to step 2.
-OR-
If your notebook is on and is not plugged into an AC 
outlet, save your work and turn off the notebook.
2Turn your notebook over so the bottom is facing up.
3Slide the battery lock to the unlocked position .
4Slide the battery release latch, then slide the battery out 
of the notebook.
5Slide a recharged battery into the notebook until it snaps 
into place.
6Slide the battery lock to the locked position .
7Turn your notebook over.
8Open the LCD panel. Warning
Danger of explosion if battery is incorrectly replaced.
Replace only with a battery specifically manufactured for your Gateway notebook. 
Discard used batteries according to local hazardous material regulations.
The battery used in this device may present a fire or chemical burn hazard if 
mishandled. Do not disassemble, heat above 212°F (100°C), or incinerate. Dispose 
of used batteries promptly. Keep away from children.
CautionIf your notebook is connected to AC power you can change the battery 
while the notebook is turned on. If your notebook it is not plugged into an AC 
outlet, you must turn the notebook off while changing the battery. 
						

							CHAPTER 5: Managing Power

Recalibrating the battery
If your notebook unexpectedly goes into Sleep 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:  
1Connect your notebook to AC power and let the battery 
charge completely.
2As soon as it starts and you see a startup screen, press 
F2. The BIOS Setup utility opens.
3Open the Advanced menu.
4Highlight Battery Auto Learning, then select Enabled 
by pressing the spacebar.
5Open the Exit menu, highlight Exit Saving Changes, 
then press ENTER.
6Select Ye s, then press ENTER.
The battery recalibration process begins and a screen 
opens showing you the progress. The entire process 
takes several hours.
When the recalibration has finished, the message “Press 
[Esc] key to exit” appears.
7Press ESC. The battery charge indicator now displays an 
accurate battery charge. Important
Do not interrupt the battery recalibration process. If recalibration is 
interrupted, you must start the process over again.
ImportantIf, after completing this procedure, the battery charge indicator still does 
not show an accurate charge, contact Gateway Customer Care at the location 
shown on the Customer Care label. For more information, see “Gateway contact 
information” on page 3.

Extending battery life
Maximizing battery performance
To get maximum performance from your notebook battery, we 
recommend that you initially condition (fully charge and 
discharge) your new battery a few times during the first 
several weeks of use, to let it reach its maximum rated capacity.
Over the long term, use the battery at least once a month, even 
if it was kept in a cool, dry place for storage, but avoid frequent 
full discharges because this puts additional strain on the 
battery. Several partial discharges with frequent recharges are 
better for a lithium-ion battery than one complete discharge, 
and recharging a partially charged lithium-ion battery does not 
cause harm because there is no memory.
Conserving battery power
To conserve power while using the battery to power your 
notebook:
Turn off wireless networking and Bluetooth.
Dim the display as low as is comfortable.
Disconnect all external devices, like IEEE 1394 and USB 
devices.
Remove Express Cards when you do not need them. 
Many Express Cards use a small amount of power while 
inserted, even if they are not being used.
Select the Power saver power plan to get maximum 
power savings.
Close 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.
Use Hibernate mode for maximum power savings while 
your notebook is not in use.
Use the notebook touchpad instead of an external 
mouse.
Decrease or mute speaker volume.
Turn off all scheduled tasks.
Turn off auto-save features in Microsoft Office and other 
applications.Tip
For more information about using power plans, see “Changing 
notebook power settings” on page 74. 
						

							CHAPTER 5: Managing Power
72
Copy programs from CDs or DVDs to the hard drive so 
you do not use battery power by running optical drives.
Use the CD or DVD drive only when necessary. This drive 
uses 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 68.
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, an automobile power outlet, or an 
automobile cigarette lighter, use an airplane/ 
automobile power adapter or power inverter. 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:
Sleep - while your notebook is in Sleep mode, 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 
you r 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.Tip
For more information about traveling with your notebook, see 
“Traveling with Your Notebook” on page 77.
