NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. CHECK THE BATTERY STATUS LIGHT - If the battery status light flashes orange or is a steady orange the battery charge is low or depleted. Connect the computer to an electrical outlet. If the battery status light flashes blue and orange, the battery is too hot to charge. Shut down the computer, disconnect the computer from the electrical outlet, and then let the battery and computer cool to room temperature. If the battery status light rapidly flashes orange, the battery may be defective. Contact Dell. See "Contacting Dell" on page 150. CHECK THE BATTERY TEMPERATURE - If the battery temperature is below 0° C (32° F), the computer will not start up. TEST THE ELECTRICAL OUTLET - Ensure that the electrical outlet is working by testing it with another device, such as a lamp. CHECK THE AC ADAPTER - Check the AC adapter cable connections. If the AC adapter has a light, ensure that the light is on.

RESEAT THE MEMORY MODULES - If the computer power light turns on but the display remains blank, reinstall the memory modules. See "Memory" on page 129. Ensuring Sufficient Power for Your Computer Your computer is designed to use a 150-W AC adapter. For optimum system performance, you should always use a 150-W adapter. Using less-powerful AC adapters will cause you to receive a WARNING message.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
