Extending battery life
Conserving battery power
While using the battery to power your convertible tablet PC, conserve power by:
■Dimming the display as low as is comfortable. For dim or dark 
environments, use the XtraBright/XtraDim button to set your display to 
the dimmest setting possible.
■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 165.
■Closing the LCD panel to turn off the display while you are not using your 
convertible tablet PC. The display stays off until you open the panel again.
■Using Hibernate mode for maximum power savings while your convertible 
tablet PC is not in use. For more information, see “Activating and using 
Hibernate mode” on page 170.
■Using the DVD or DVD/CD-RW drive only when necessary. These drives 
use a large amount of power.
■Recharging the battery often, taking an extra battery, and fully recharging 
the batteries before traveling. For more information, see “Recharging the 
battery” on page 157 and “Changing batteries” on page 159.
■Turning off the Power on Lid Lift feature. For more information, see 
“Turning on the Power on Lid Lift feature” on page 169.

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 automobile cigarette lighter, use a power 
inverter or automobile/airplane 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 convertible 
tablet PC’s battery:
■Standby - while your convertible tablet PC 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 convertible tablet PC 
completely off. The next time you turn on your convertible tablet PC, 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 170.
Using power saving modes
Always save your work before using Standby mode. In Standby mode, your 
convertible tablet PC 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 convertible tablet PC saves all memory 
information to the hard drive, then turns the power completely off.

Changing power settings
You can change the function of the power switch, Standby system key, and 
power-saving timers by changing power settings on your convertible tablet PC.
You can customize power settings from the Windows Control Panel by selecting 
power schemes, setting power alarms, adjusting advanced power settings, and 
activating Hibernate mode.
Power schemes (groups of power settings) let you change power saving options 
such as when the display or hard drive is automatically turned off. You can 
select one of the defined power schemes or create a custom power scheme.
Alarms can alert you when the battery charge is low.
Advanced power settings let you assign different power saving modes to the power 
switch and Standby system key. You can also select which power saving mode 
is activated when you close the LCD panel.
ImportantThe processor installed in your convertible tablet PC may 
use Intel® SpeedStep™ technology to conserve battery 
power. A SpeedStep-equipped processor can change its 
operating speed according to the power source. Your 
convertible tablet PC’s default settings operate the 
processor at full speed while connected to AC power and 
at reduced speed (which uses less power) while using 
battery power. Power schemes also set the speed of an 
Intel
® SpeedStep™-equipped processor.
