Dell XPS Keyboard Not Working

Windows is developed for many languages and regional keyboard layouts. If your keys are not outputting the characters you expect, check these settings first.

• Check the lower left corner near the system tray for a language switcher (or Language Bar). Opening it allows you to select from installed languages or regional keyboards.
• Check the region and keyboard settings for the currently selected language. Select the correct option if the setting is not what you expect
• By default, pressing Left Alt + Shift toggles between input languages. It won't work unless the language bar is enabled, but it might be the reason you're randomly typing in Russian when you're trying to coordinate an in-game raid.
• If the language bar is not showing, but this seems to be your issue, check Windows language settings and set them appropriately. They can be found in the Settings menu under Time & Language.

In addition to multiple language support, Microsoft built features to improve accessibility for people who experience typing difficulties. Enabling some of these settings inadvertently could make you think your keyboard isn't responding.

• Try typing by long pressing keys instead of typing rapidly as usual. A good test is to hold the CAPS lock key for a few seconds to see if the LED will light.
• If you can type with long presses, you must disable Filter Keys, a setting intended for those who might accidentally nudge other keys while typing.
• Check your settings in the Ease of Access menu within the Settings app or Control Panel. Scroll to the Keyboard section and verify that all settings are correct.

Dirt or debris can find its way under your keyboard keys and affect the switches, especially if you are prone to spills. iFixit does feature an article on fixing sticky laptop keys. However, we included a brief guide on cleaning your keyboard with high-concentration isopropyl alcohol (at least 90% is recommended) below.

• Start by shutting the computer down. This will prevent key presses from making accidental changes during the cleaning.
• Turn the keyboard upside down and use a soft-bristled brush (a new toothbrush should work fine) to wipe any hard debris from under the keys. Be sure to pay special attention to particularly sticky or problematic areas.
• Wipe the keyboard with a cotton swab or cloth dampened with isopropyl alcohol.
  • If you know there was a spill or the material is incredibly sticky, use a weaker concentration and allow some extra time for drying. The water in a weaker solution (about 75%) will dissolve grime more effectively but will take longer to evaporate.
• If you are able, remove the keycaps to check for debris. The switches are easy to damage, so be as gentle as possible.
• Allow the keyboard to dry, then turn on your laptop to check if functionality has returned.

If you are running a particularly demanding application on your computer, it may be interfering with your keyboard input. To test this, perform the following steps.

• Close all open programs, then open a single one. Is it any better? Reopen any other programs you had open to attempt to recreate the issue.
• Uninstall any programs that are interfering.
• Run a virus scan to ensure no malware is impacting keyboard function. It is unusual but not unheard of.

BIOS settings are stored in a computer's firmware, and hardware and OS communication is configured. Check these settings to ensure proper keyboard recognition and configuration, potentially resolving unresponsiveness.

• Access the BIOS by connecting an external keyboard and turning on your laptop. Press F2 several times when the Dell logo appears onscreen.
  • Timing is critical; you may need to try a few times to get in successfully.
• Check any BIOS settings relating to the keyboard. Be sure it is enabled and configured correctly within the BIOS setup.

Even if your keyboard would work perfectly otherwise, without a way to get signals to the motherboard, it won't function at all. This is more common after a repair but can occur regardless.

• Inspection is likely to reveal signs of a bad cable. Look closely at corners and connectors. Punctures, creases, or tears can impede cable function. If you find any damage, replace the cable.
• Be sure the cable is properly inserted. The location and width of the motherboard connector make this connection difficult to get right.
• Verify the locking tab on the board connector is present and locked (tab flipped down). If the connector for this ribbon cable isn't locked correctly, the connection can loosen over time.
  • If the locking tab has come free of the connector it can be repaired as long as you still have the missing piece.
• Not all models will have a keyboard cable that is a separate part from the keyboard itself. Check that the keyboard uses a cable that can be disconnected from both ends. If the cable is integrated into the keyboard, you'll need to replace the entire keyboard, not just the faulty cable.

Ultimately, it may come down to an issue with the keyboard itself. This is typically a result of liquid damage but can occur regardless. Keyboards often come as part of an assembly but are independently replaceable in some models.

• If columns or rows of keys are not functioning without liquid damage or you have been unsuccessful at getting responses from some keys, replacing the keyboard is the likeliest solution.

If all the above tips have failed, there is likely an issue with your laptop's motherboard.

• Inspect both sides of the motherboard for any signs of physical damage, such as burnt components, liquid residue, corrosion, or other visible issues.
• If your motherboard's components aren't functioning correctly, you will likely need to source a replacement board.
• Circuit boards can often be repaired by a knowledgeable technician with soldering (or microsoldering) experience. Ask your local repair shops if this isn't something you think you could do yourself.
