Extending battery life 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. www.gateway.com 163
