Ensuring Sufficient Power for Your Computer

Your computer’s Intel® Mobile Pentium®4 microprocessor requires more power than the microprocessors used in Dell’s previous portable computers. Your computer is designed to use the 90-W AC adapter and the 4400-mAh battery that shipped with it; for optimum system performance, you should always use these components.

The 70-W AC adapters used in some of Dell’s older portable computers can be used with your computer, but they will decrease system performance. Likewise, you can use the 3800-mAh and 3600-mAh batteries from older Dell computers, but these lesser-capacity batteries will discharge faster. Using less-powerful AC adapters or batteries may cause you to receive a WARNING or a SYSTEM CONFIGURATION ERROR message similar to the following:

WARNING: 70 Watt AC adapter detected. System will not be capable of running in full performance without a 90 Watt AC adapter.
