Certain keys on Inspiron Laptop keyboard do not respond

Typing this with a separate USB keyboard for now, but does anyone know the best way to go about repairing the keyboard on my Inspiron 16 7620 2-in-1 laptop? A select few keys (specifically 6, 7, u, h, j, n, m, and the down arrow) have no response. I'd like to see the most cost-effective options available to me, considering college expenses.

Hello,

This is usually a hardware issue with the keyboard. Underneath the keyboard, there is a circuit board with numerous signal tracks. Cracks in the tracks, dust or debris buildup, or corrosion can disrupt the signal flow.

If the USB keyboard works, that only proves further that it is hardware issue. Unfortunately that's not a Microsoft issue and it is beyond what this forum can help. You need to contact Dell support, or take it to local repair place.

    Start with the lowest-cost checks to separate a Windows/input issue from a hardware keyboard failure:

    1. Test the On-Screen Keyboard.
      • Press Windows key + Ctrl + O to open it.
      • Try the affected keys there.
      • If the On-Screen Keyboard works normally while the built-in laptop keys do not, that points more toward the physical keyboard or its driver rather than general text input in Windows.
    2. Check Accessibility keyboard settings.
      • Go to Start > Settings > Accessibility > Keyboard.
      • Make sure features such as Sticky Keys, Toggle Keys, and especially Filter Keys are not causing unexpected keyboard behavior.
      • This is low risk and free.
    3. Verify the keyboard/input language.
      • Go to Start > Settings > Time & language > Region & language.
      • Make sure the keyboard input language matches the display language.
      • This is most relevant when typed characters do not match what appears on screen, but it is still worth confirming.
    4. Reinstall the keyboard driver.
      • Open Device Manager.
      • Expand Keyboards.
      • Right-click the keyboard and choose Uninstall.
      • Restart the PC so Windows reinstalls the driver.
      • This is one of the main no-cost troubleshooting steps in the provided guidance.
    5. Check Windows Update.
      • Go to Start > Settings > Update & Security > Windows Update.
      • Install the latest updates.
      • Microsoft guidance notes that special keys not functioning can mean the PC does not have the latest updates.
    6. Compare with the USB keyboard result.
      • Since a separate USB keyboard is already working, that strongly suggests the issue is isolated to the built-in keyboard path rather than all keyboard input in Windows.

    Most cost-effective path:

    • First use the free software steps above: On-Screen Keyboard test, Accessibility settings, driver reinstall, and Windows Update.
    • If those do not change anything, the pattern of the same built-in keys failing while a USB keyboard works is more consistent with a hardware problem on the laptop keyboard itself.
    • In that case, the practical low-cost workaround is continuing with the USB keyboard until repair is affordable.

    If more help is needed after the software checks, Windows support guidance also points to Get Help for additional support.
