Back to Contents Page Advanced Troubleshooting Dell™ XPS™ 410 Service Manual Power Lights Diagnostic Lights Beep Codes Dell Diagnostics Drivers Resolving Software and Hardware Incompatibilities Power Lights The power button light located on the front of the computer illuminates and blinks or remains solid to indicate different states: l If the power light is green and the computer is not responding. . Ensure the display is connected and powered on. . If the display is connected and powered on, see Diagnostic Lights. l If the power light is blinking green, the computer is in standby mode. Press a key on the keyboard, move the mouse, or press the power button to resume normal operation. l If the power light is off, the computer is either turned off or is not receiving power. . Reseat the power cable into both the power connector on the back of the computer and the electrical outlet. . If the computer is plugged into a power strip, ensure that the power strip is plugged into an electrical outlet and that the power strip is turned on. Also bypass power protection devices, power strips, and power extension cables to verify that the computer turns on properly. . Ensure that the electrical outlet is working by testing it with another device, such as a lamp. . Ensure that the main power cable and front panel cable are securely connected to the system board (see System Board Components). l If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist. . Ensure that the voltage selection switch is set to match the AC power at your location (if applicable). l If the power light is steady amber, a device might be malfunctioning or incorrectly installed. . Remove and then reinstall the memory modules (see Installing Memory). . Remove and then reinstall any cards (see Cards). . Remove and then reinstall the graphics card, if applicable (see Cards). . Ensure that all power cables are securely connected to the system board. (see System Board Components). Diagnostic Lights To help you troubleshoot a problem, your computer has four lights labeled 1, 2, 3, and 4 on the front panel (see Front View of the Computer). When the computer starts normally, the lights flash before turning off. If the computer malfunctions, the sequence of the lights help to identify the problem. . CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide. CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the Product Information Guide. Light Pattern Problem Description Suggested Resolution The computer is in a normal "off" condition or a possible pre-BIOS failure has occurred. All four diagnostic lights display solid green and then turn off after the system successfully boots to the operating system. l Plug the computer into a working electrical outlet (see Power Lights) A possible processor failure has occurred. Reinstall the processor (see Installing the Processor) and restart the computer. Beep Codes Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. For example, beep code 1-3-1 consists of one beep, a burst of three beeps, and then one beep.This beep code tells you that the computer encountered a memory problem. Reseating the memory modules (see Installing Memory) may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance. The following table lists beep codes for non memory related errors. Memory modules are detected, but a memory failure has occurred. l If two or more memory modules are installed, remove the modules (see Removing Memory), then reinstall one module (see Installing Memory) and restart the computer. If the computer starts normally, continue to install additional modules (one at a time) until you have identified a faulty module or reinstalled all modules without error. l If available, install properly working memory of the same type into your computer (see Installing Memory). A possible graphics card failure has occurred. l Reseat any installed graphics card (see Installing a PCI Express Card). l If available, install a working graphics card into your computer. A possible floppy drive or hard drive failure has occurred. Reseat all power and data cables. A possible USB failure has occurred. Reinstall all USB devices and check all cable connections. No memory modules are detected. l If two or more memory modules are installed, remove the modules (see Removing Memory), then reinstall one module (see Installing Memory) and restart the computer. If the computer starts normally, continue to install additional modules (one at a time) until you have identified a fault...
