WARNING: Before working inside your computer, read the safety information that shipped with your computer. For more safety best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance. 12 WARNING: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the computer, replace all covers, panels, and screws before connecting to the electrical outlet. CAUTION: To avoid damaging the computer, ensure that the work surface is flat and clean. CAUTION: To avoid damaging the components and cards, handle them by their edges, and avoid touching pins and contacts. CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the safety instructions that shipped with the product or at www.dell.com/regulatory_compliance. CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal components. CAUTION: When you disconnect a cable, pull on its connector or on its pull tab, not on the cable itself. Some cables have connectors with locking tabs or thumb-screws that you must disengage before disconnecting the cable. When disconnecting cables, keep them evenly aligned to avoid bending any connector pins. When connecting cables, ensure that the ports and connectors are correctly oriented and aligned. CAUTION: Press and eject any installed card from the media-card reader.

Using this program with other computers may cause invalid results or error messages. The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device groups allowing you to: • Run tests automatically or in an interactive mode • Repeat tests • Display or save test results • Run thorough tests to introduce additional test options to provide extra information about the failed device(s) • View status messages that inform you if tests are completed successfully • View error messages that inform you of problems encountered during testing NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal when the diagnostic tests are performed. For more information, see Dell EPSA Diagnostic 3.0. Running the ePSA diagnostics 1 Power-on the computer. 2 As the computer boots, press the F12 key as the Dell logo appears. 3 On the boot menu screen, select the Diagnostics option. 4 Click the arrow key at the bottom left corner. Diagnostics front page is displayed. 5 Press the arrow in the lower-right corner to go to the page listing. The items detected are listed. 152 6 To run a diagnostic test on a specific device, press Esc and click Yes to stop the diagnostic test. 7 Select the device from the left pane and click Run Tests. 8 If there are any issues, error codes are displayed. Note the error code and validation number and contact Dell. System diagnostic lights The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working appropriately before the boot process begins. If the computer passes the POST, the computer continues to start in a normal mode. However, if the computer fails the POST, the computer emits a series of LED codes in amber color during the start-up. The following table shows different light patterns and what they indicate. Table 9. Diagnostics Number of Power LED flashes Problem description 1 System board: BIOS and ROM failure 2 No memory or RAM detected 3 System board or chipset error 4 Memory or RAM failure 5 CMOS battery failure 6 Video card or chip failure 7 CPU failure 3,6 BIOS recovery image not found 3,7 BIOS recovery image found but invalid Flea power release Flea power is the residual static electricity that remains on the computer even after it has been powered off. The following procedure list the steps to conduct a flea power release for the computer. 1 Turn off your computer. 153 2 Disconnect the power cable. 3 Press and hold down the power button for 15 seconds to drain the flea power. 4 Connect the power cable. 5 Turn on your computer. Wi-Fi power cycle If your computer is unable to access the internet due to Wi-Fi connectivity issues a Wi-Fi power cycle procedure may be performed. The following procedure provides the instructions on how to conduct a Wi-Fi power cycle: NOTE: Some ISPs (Internet Service Providers) provide a modem/ router combo device. 1 Turn off your computer. 2 Turn off the modem. 3 Turn off the wireless router. 4 Wait for 30 seconds. 5 Turn on the wireless router. 6 Turn on the modem. 7 Turn on your computer. 154 Getting help and contacting Alienware Self-help resources You can get information and help on Alienware products and services using these online self-help resources: Table 10.
