How to Troubleshoot and Fix a Keyboard That Is Not Working

Published 2026-10-14 · LuxuriousComputers Repair

Your keyboard has stopped responding. Keys do not register when pressed, or only some keys work while others do not. The problem may affect an external USB or wireless keyboard, a laptop built-in keyboard, or a Bluetooth keyboard. Keyboard failures range from simple connection issues to driver problems or hardware damage. This guide covers systematic troubleshooting for all keyboard types on Windows computers.

Check the physical connection

  • For USB keyboards, unplug the cable and plug it back in firmly. Try a different USB port — the original port may be damaged or unpowered. Avoid USB hubs for initial testing and plug directly into a port on the computer. If the keyboard has a USB passthrough or indicator lights, check whether they illuminate when connected
  • For wireless keyboards, check the battery level. Replace the batteries or charge the keyboard if it uses a rechargeable battery. Low battery is the most common reason a wireless keyboard stops working. Also check that the wireless receiver (USB dongle) is plugged in securely and not hidden behind other USB devices that might block the signal
  • For Bluetooth keyboards, verify it is paired and connected. Open Settings, Bluetooth and Devices, and check that the keyboard shows as Connected. If it shows as Paired but not Connected, click on it and select Connect. If it does not appear at all, put the keyboard into pairing mode (usually by holding a pairing button) and add it again

Test with a different keyboard

  • Plug in a different keyboard to determine whether the problem is with the keyboard hardware or with your computer. If a different keyboard works normally, the original keyboard has a hardware problem. If a different keyboard also fails, the problem is with the computer (driver, USB controller, or Windows settings)
  • For laptop keyboards, connect an external USB keyboard. If the external keyboard works but the built-in keyboard does not, the laptop keyboard hardware or its ribbon cable connection may be damaged. If both keyboards fail, it is a software or driver issue
  • Try the keyboard on a different computer to verify whether the keyboard itself is functional. A keyboard that works on another computer but not on yours confirms the issue is computer-side

Check if the keyboard works in BIOS

  • Restart the computer and press the BIOS key (usually Delete, F2, or F10) during startup. If you can enter BIOS and navigate using the keyboard, the keyboard hardware is working and the problem is with Windows — a driver, setting, or software conflict
  • If the keyboard does not work in BIOS, the problem is hardware or connection related. For USB keyboards, try different ports. For laptop keyboards, the connection between the keyboard and the motherboard may be loose. For wireless keyboards, BIOS typically does not support Bluetooth — try the wired USB receiver or a wired keyboard for BIOS access

Update or reinstall the keyboard driver

  • Open Device Manager (right-click the Start button, select Device Manager). Expand the Keyboards section. Right-click your keyboard device and select Update Driver, then Search Automatically. If Windows finds a newer driver, install it and test the keyboard
  • If updating does not help, uninstall the driver. Right-click the keyboard in Device Manager and select Uninstall Device. Restart the computer. Windows automatically reinstalls the keyboard driver during startup. This resolves corrupted driver installations
  • If the keyboard has a yellow warning triangle in Device Manager, the driver has an error. Note the error code in Properties, then uninstall and reinstall the driver. For persistent errors, download the keyboard driver from the manufacturer website

Check keyboard settings in Windows

  • Filter Keys may be causing the keyboard to ignore keystrokes. Filter Keys ignores brief or repeated key presses. Open Settings, Accessibility, Keyboard, and ensure Filter Keys is turned off. When Filter Keys is active, you must hold each key for a minimum duration before it registers
  • Sticky Keys and Toggle Keys can change how the keyboard behaves. In the same Accessibility Keyboard settings, turn off Sticky Keys and Toggle Keys if they are enabled and you did not intend to use them
  • Check the input language and keyboard layout. Open Settings, Time and Language, Language and Region. If the wrong language is selected, keys may produce unexpected characters or appear non-functional. Press Windows plus Space to switch between installed keyboard layouts

Fix laptop keyboard issues

  • Laptop keyboards connect to the motherboard via a ribbon cable under the keyboard. If the laptop was recently opened for repair or the keyboard was bumped hard, the ribbon cable may have come loose. Reconnecting it requires opening the laptop — if you are comfortable with this, search for your laptop model keyboard replacement guide to see how to access the ribbon cable
  • Some laptops have a function lock that disables the regular key functions and activates the function key shortcuts instead. If number keys produce volume changes or brightness adjustments, press the Fn lock key (often Fn plus Escape or a dedicated lock key) to toggle back to normal mode
  • Spills are a common cause of laptop keyboard failure. If liquid was spilled on the keyboard, individual keys or sections may stop working as residue corrodes the contacts. A laptop keyboard replacement is often necessary after a liquid spill

Check for USB power management issues

  • Windows may be turning off USB ports to save power, which disconnects the keyboard. Open Device Manager, expand Universal Serial Bus Controllers, right-click each USB Root Hub, select Properties, go to the Power Management tab, and uncheck Allow the Computer to Turn Off This Device to Save Power
  • Also check the Windows power plan settings. Open Control Panel, Power Options, Change Plan Settings, Change Advanced Power Settings. Expand USB Settings, USB Selective Suspend Setting, and set it to Disabled. This prevents Windows from power-managing USB ports

Run the keyboard troubleshooter

  • Windows includes a built-in keyboard troubleshooter. Open Settings, System, Troubleshoot, Other Troubleshooters, and find Keyboard. Click Run. The troubleshooter checks driver status, service configuration, and common keyboard settings issues
  • The troubleshooter may identify and fix problems automatically, or it may report findings that require manual action. Follow any recommendations it provides. After the troubleshooter completes, test the keyboard

Check for malware or conflicting software

  • Some malware intercepts keyboard input. If the keyboard stopped working after installing software or visiting a suspicious website, run a full malware scan with Windows Security and follow up with Malwarebytes. Keyboard loggers and other malware can interfere with normal keyboard operation
  • Remote desktop software, game controllers, virtual keyboard applications, and keyboard remapping tools can conflict with normal keyboard input. If you recently installed any such software, try uninstalling it to see if the keyboard returns to normal
  • Boot into Safe Mode to test whether third-party software is the cause. In Safe Mode, only essential drivers load. If the keyboard works in Safe Mode, a startup program or third-party driver is causing the conflict
