CHAPTER 3: Setting Up and Getting Started Avoiding discomfort and injury from repetitive strain • Vary your activities to avoid excessive repetition. • Take breaks to change your position, stretch your muscles, and relieve your eyes. • Find ways to break up the work day, and schedule a variety of tasks. Connecting the AC adapter You can run your notebook using an AC adapter or your notebook's battery. The battery was shipped to you partially charged. You should use the AC adapter right away to fully charge the battery. Allow three hours for the battery to fully charge. Power subsystem 19V DC, 65/90W AC adapter Temperature: Operating: 5 °C ~ 35 °C Non-operating: -20 °C ~ 65 °C Warning Do not attempt to disassemble the AC adapter. The AC adapter has no user-replaceable or user-serviceable parts inside. The AC adapter has dangerous voltages that can cause serious injury or death. Contact Gateway about returning defective AC adapters. Caution Make sure that you use the AC adapter that came with your notebook or one of the same type purchased from Gateway. Replace the power cord if it becomes damaged. The replacement cord must be of the same type and voltage rating as the original cord or your notebook may be damaged. Important If the battery is not fully charged before you use your notebook on battery power for the first time, the battery life may be much shorter than you expect. If the battery life seems short even after being charged for three hours, the battery may need to be recalibrated. For information on recalibrating the battery, see "Extending battery life" on page 58. 18
