Providing Power Providing Power AC Adapter Your computer can be operated with the AC Adapter or battery pack. The AC Adapter supplies power for the computer. The AC Adapter also charges the battery pack when the battery pack is installed in the computer. The input rating for the AC Adapter is 100-240 V ac, 50/60 Hz. DANGER Do not attempt to open the AC Adapter case. The AC Adapter is permanently sealed and cannot be repaired. Attention: Always use an AC Adapter certified by IBM in the country where you will be using the computer. Operating the computer with an incorrect AC Adapter can cause damage to the battery pack and to the computer. If you turn on the computer with the battery pack installed, you will hear a short beep when you connect or disconnect the AC Adapter from the computer. This short beep means that the power source has been changed. When the AC Adapter cable is disconnected from the computer with a battery pack installed, the LCD brightness decreases slightly to conserve battery power.

The battery pack can be recharged with the AC Adapter or the battery charger (available as an option). Battery packs are shipped from the factory in an almost discharged state, so you must charge them before use. To operate your computer with the battery pack, see Chapter 4. Chapter 2.
