System board built-in self-test (M-BIST) About this task Steps 1. Press and hold both the M key and the power button to initiate M-BIST. 2. The battery-status light illuminates in amber when there is a system board failure. 3. Replace the system board to fix the issue. NOTE: The battery status LED does not illuminate if the system board is functioning properly.
Display panel power rail built-in self-test (L-BIST) About this task Next steps L-BIST (LCD Power Rail Test) is an enhancement to the single LED error code diagnostics and is automatically initiated during POST. L-BIST isolates if the LCD is receiving power from the system board. L-BIST checks if the system board is supplying power to the LCD by performing an LCD Power Rail test. If there is no power going to the LCD, the battery status LED flashes a [2,8] LED error code.
NOTE: The sequence of colors may vary depending on the different display panel vendors. The user only must ensure that the colors are being displayed correctly without distortion or graphical anomalies. 4. The computer reboots at the end of the last solid color. Dell SupportAssist Pre-boot System Performance Check diagnostics About this task SupportAssist diagnostics (also known as system diagnostics) performs a complete check of your hardware.
For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause. This 2,3 pattern continues until the computer is turned off indicating no memory or RAM is detected. The following table shows different power and battery-status light patterns and associated problems. Blinking Pattern Problem description Suggested resolution 1 1 TPM detection failure Replace the system board.
Camera status light: Indicates whether the camera is in use. ● Solid white — Camera is in use. ● Off — Camera is not in use. Caps Lock status light: Indicates whether Caps Lock is enabled or disabled. ● Solid white — Caps Lock enabled. ● Off — Caps Lock disabled. Recovering the operating system When your computer is unable to boot to the operating system even after repeated attempts, it automatically starts Dell SupportAssist OS Recovery.
8. After the download is complete, navigate to the folder where you saved the BIOS update file. 9. Double-click the BIOS update file icon and follow the instructions on the screen. WiFi power cycle About this task If your computer is unable to access the internet due to WiFi connectivity issues a WiFi power cycle procedure may be performed.
