Connecting to the Internet using Ethernet cable (LAN)
- Connect the Ethernet (LAN) cable to the modem or router and to the personal computer.
- Check for activity lights (LEDs) on the modem or router and the personal computer.
NOTE: Some PCs may not have activity lights on the Ethernet (LAN) port. See the User Manual of your personal computer for more information.
- Open a web browser (e.x Internet Explorer or Google Chrome or Mozilla Firefox) to verify Internet connection.

Dell SupportAssist
- Using the SupportAssist application provides automatic computer updates and detects issues that will be resolved for you. Let us take the effort out of maintaining your Dell Computer or Tablet. For more information about SupportAssist, browse to the SupportAssist for PCs and tablets page.
- To run online hardware diagnostics to ensure that your hardware is working correctly, see the Dell knowledge-base article Resolve Hardware Issues With Integrated and Online Diagnostics (SupportAssist ePSA, ePSA, or PSA Error Codes). The article explains how to access the hardware diagnostics and the different kinds of test available for your Dell computer or tablet.
NOTE: The diagnostics will either fix the problem automatically, or it will guide you through the steps to resolve the problem. When the diagnostic identifies a failing part, depending on the failing part, we will immediately start the process for a free in-warranty replacement part.
- When the computer cannot access the Internet, you can run the integrated diagnostics (ePSA) on your computer. For more information, see the Dell knowledge-base article Resolve Hardware Issues Using ePSA or PSA Diagnostics and Guide to Error Codes.
Dell Enhanced Preboot System Assessment (ePSA) diagnostics
The Dell ePSA diagnostics perform a complete check of your computer hardware. The ePSA is embedded in the BIOS and is launched by the BIOS internally (from the advanced boot menu). The embedded computer diagnostics provide 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 one or more failed devices
- View status messages that inform you if tests are completed successfully
- View error messages that inform you of problems encountered during testing
Launching ePSA diagnostics
- Power off the computer.
- Power on the computer and tap F12 key (at the Dell logo screen) until One Time Boot menu appears.
- On the boot menu, select Diagnostics using the arrow keys on the keyboard.
- Press the Enter key to begin ePSA diagnostics.
NOTE: ePSA diagnostic tests for specific devices are interactive and requires user input or interaction. Always ensure that you are present at the computer terminal when the diagnostic tests are performed. The touchpad and mouse will be nonfunctional when the test is in progress.

LCD Integrated Self-Test (BIST)
Dell 24 (5475) All-in-One personal computer includes an LCD-integrated self-test (BIST) feature that helps you determine if the screen abnormality you are experiencing is a problem with the monitor or with the video card on your computer, diagnose, and inspect the entire LCD for color purity, better identify defects such as stuck pixels or dead pixels, identify cracks in the LCD that may not be apparent in a normal viewing mode.
When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade so on, it is always a good practice to isolate the LCD by running the integrated self-test diagnostics.
- Power off the personal computer.
- Hold the OSD (On-Screen Display) button at the bottom-right of the personal computer.
- While holding the OSD button, press the Power button to start integrated self-test (BIST).
- A series of colors will flash on-screen.
- Carefully inspect the screen for abnormalities.
NOTE: If you do not detect any screen abnormalities in integrated self-test (BIST) mode, the LCD is functioning properly. Check the video card (GPU) and personal computer settings.
If you notice any abnormalities in integrated self-test (BIST) mode, you may get the monitor repaired or replaced if it is under warranty by contacting Dell Technical Support.
