Optimizing Power Consumption and Battery Charge Time The AC adapter charges a completely discharged battery in approximately 3 hours with the computer turned off. Charge time is significantly longer if the computer is on and running at high processor speeds and system activity levels. If you run your computer at high system activity levels for extended periods of time and your battery is not charging, try running your system in Low Power Mode. Low Power Mode can improve battery charge time and battery life. Depending on system activity levels, system performance may be reduced. To set Low Power Mode: NOTE: You can also click the power meter icon on the taskbar. 1 Click the Start button→Control Panel→Performance and Maintenance→Power Options. 2 Click the Power Schemes tab. 3 In the Power schemes drop-down menu, click Low Power Mode. For more information on power management, see the Dell Inspiron Help file. To access the help file, see page 9. Variable Speed Fan The computer uses a variable speed fan to prevent the computer from overheating. The fan runs constantly, and fan speed may vary depending on usage. Fan noise is normal and does not indicate a problem with the fan or the computer. Dell Technical Support Policy (U.S. Only) Technician-assisted technical support requires the cooperation and participation of the customer in the troubleshooting process and provides for restoration of the operating system, software programs, and hardware drivers to the original default configuration as shipped from Dell, as well as the verification of appropriate functionality of the computer and all Dell-installed hardware. In addition to this technician-assisted technical support, online technical support is available at support.dell.com. Additional technical support options may be available for purchase. Dell provides limited technical support for the computer and any "Dell-installed" software and peripherals1. Support for third-party software and peripherals is provided by the original manufacturer, including those purchased and/or installed through Dell Software and Peripherals, Readyware, and Custom Factory Integration2. 1 Repair services are provided pursuant to the terms and conditions of your limited warranty and any optional support service contract purchased with the computer. 2 All Dell-standard components included in a Custom Factory Integration (CFI) project are covered by the standard Dell limited warranty for your computer.
