How to Fix a Keyboard That Is Not Typing

Published 2026-10-16 · Marion Remote Fix

You press keys on the keyboard and nothing appears on screen — no characters, no response. The computer is on, the mouse works, but the keyboard does nothing. Or some keys work but others do not. Or the keyboard types the wrong characters. Each of these symptoms points to a different cause, and the fix depends on whether you are using a USB keyboard, wireless keyboard, Bluetooth keyboard, or a laptop's built-in keyboard.

Is the keyboard connected

Start with the physical connection, because a surprisingly large percentage of keyboard-not-typing problems are connection problems:

USB keyboards

  • Unplug the USB cable and plug it back in. Try a different USB port — if the keyboard is plugged into a USB hub, try plugging directly into a port on the back of the computer (these are connected directly to the motherboard and receive more reliable power than front panel ports or hubs)
  • Check the USB connector for debris or bent pins. Try the keyboard on a different computer to confirm it works. If the keyboard has two USB connectors (one for data, one for passthrough), both may need to be connected

Wireless keyboards (USB receiver)

  • Replace the batteries even if you think they have charge — low battery behavior looks identical to a broken keyboard
  • Remove the USB receiver and plug it into a different port. Toggle the keyboard power switch off and back on. Press the Connect or Pairing button (usually on the bottom) to re-establish the connection
  • 2.4 GHz keyboards can experience interference from Wi-Fi routers, cordless phones, and microwaves. Try moving the receiver closer to the keyboard

Bluetooth keyboards

  • Verify Bluetooth is enabled: Settings, Bluetooth and devices. Bluetooth keyboards enter deep sleep to save battery — press a key and wait 3 to 5 seconds before concluding it is broken
  • Remove and re-pair the keyboard. In Bluetooth settings, remove the device, then put the keyboard into pairing mode (hold the Bluetooth button until the LED flashes) and add it again
  • If the keyboard was recently paired to another device (phone, tablet, second computer), it may still be connected there. Multi-device keyboards have a button to switch between paired devices

Filter Keys is turned on

This is one of the most common causes of a keyboard that seems to not type, and it is often accidentally enabled. Filter Keys is a Windows accessibility feature that ignores brief or repeated keystrokes. When Filter Keys is active, you must hold each key down for a full second before the keystroke registers. Normal-speed typing produces nothing on screen:

  • How it gets turned on accidentally: Pressing and holding the right Shift key for 8 seconds activates Filter Keys. A prompt appears asking if you want to enable it, but if you press Enter (or the prompt is auto-accepted), Filter Keys turns on. This often happens when a key gets stuck, when something is resting on the keyboard, or when a child presses and holds keys
  • How to turn it off: Go to Settings, Accessibility, Keyboard (Windows 11) or Settings, Ease of Access, Keyboard (Windows 10). Turn off Filter Keys. While you are there, also check Sticky Keys and Toggle Keys — these are other accessibility features that can change keyboard behavior unexpectedly
  • Quick test: If you suspect Filter Keys, press and hold any letter key for 2 full seconds. If the character appears after the delay, Filter Keys is the problem

Wrong keyboard layout or input language

If the keyboard types but produces the wrong characters — pressing the Z key types Y, pressing the semicolon types an accented letter, or some keys produce symbols instead of letters — the wrong keyboard layout is selected:

  • Check the language bar in the taskbar (bottom right, near the clock). It shows the current input language (ENG for English US, ENG INTL for English International, DEU for German, FRA for French, etc.). Click it and select English (United States) — US keyboard layout
  • The keyboard shortcut Win+Space or Alt+Shift cycles through installed input languages. It is easy to accidentally switch languages with these shortcuts during normal typing. If you only use one language, remove the extra languages: Settings, Time and language, Language and region. Remove any languages you do not use to prevent accidental switching
  • If the keyboard types numbers when you press letter keys on the right side of the keyboard (U types 4, I types 5, O types 6, J types 1, K types 2, L types 3), Num Lock is enabled on a keyboard that shares number pad functions with the letter keys. This is common on laptops without a dedicated number pad. Press Num Lock (or Fn+Num Lock on some laptops) to disable it

Driver problems

Keyboard drivers in Windows are usually generic and reliable, but they can occasionally become corrupted or conflict with other software:

  • Reinstall the driver: Open Device Manager (right-click Start, select Device Manager). Expand Keyboards. Right-click your keyboard device (usually listed as Standard PS/2 Keyboard or HID Keyboard Device) and select Uninstall device. Check the box for Attempt to remove the driver if available. Restart the computer. Windows will reinstall the keyboard driver automatically on boot
  • Check for Unknown devices: In Device Manager, look for any entries with a yellow triangle warning icon, especially under Keyboards or Universal Serial Bus controllers. A yellow triangle indicates a driver problem. Right-click the device and select Update driver, then Search automatically
  • USB controller issues: If all USB devices (not just the keyboard) stop working, the USB controller driver may be corrupted. In Device Manager, expand Universal Serial Bus controllers and uninstall each USB Root Hub and USB Host Controller. Restart — Windows will reinstall them
  • Keyboard software: Gaming keyboards from Corsair, Razer, Logitech, SteelSeries, and HyperX often require proprietary software (iCUE, Synapse, G Hub, GG, NGENUITY). If the keyboard stops working after a software update, try uninstalling the software, restarting, and testing the keyboard with just the default Windows driver. Then reinstall the latest version of the software from the manufacturer's website

Laptop keyboard specific issues

Laptop keyboards have additional failure modes that external keyboards do not:

  • Ribbon cable: The keyboard connects via a thin ribbon cable to the motherboard. If the laptop was recently opened or dropped, this cable may be loose. Reseating requires opening the laptop
  • Liquid damage: Any spill can corrode keyboard membrane traces, causing immediate or delayed failure. If keys stopped working after a spill (even weeks later), the keyboard needs replacement
  • Function key lock: Fn Lock reverses the function row behavior. Try pressing Fn+Esc or Fn+Caps Lock to toggle it
  • External keyboard test: Plug in a USB keyboard. If it works, the problem is the laptop keyboard hardware. If it also fails, the problem is software or the motherboard controller

Some keys not working

If most keys work but specific keys do not respond at all:

  • Debris under the key: Crumbs, dust, and hair prevent keys from making contact. Blow compressed air under the affected key. On mechanical keyboards, remove the keycap and clean underneath. On membrane keyboards and laptops, keycap removal risks breaking the scissor mechanism
  • Liquid residue: Dried liquid leaves residue that blocks contact. Clean with isopropyl alcohol after removing the keycap
  • Key rollover: Cheap membrane keyboards register only 3 to 6 simultaneous keys. Pressing too many at once (common in gaming) drops some inputs. Mechanical keyboards with N-key rollover register all keys simultaneously
  • Dead switch: On mechanical keyboards, individual switches can fail. Most modern mechanical keyboards use hot-swappable switches that can be replaced without soldering

BIOS and pre-boot keyboard

If the keyboard does not work even before Windows loads — you cannot enter the BIOS by pressing Delete or F2 at startup — the problem is at the hardware level:

  • USB keyboards require USB Legacy Support to be enabled in the BIOS to work during boot. If this setting was changed (or if the BIOS was reset to defaults on a board that defaults to disabled), the keyboard will not respond until Windows loads its USB drivers. To fix this, you need a PS/2 keyboard to access the BIOS, or you can reset the BIOS by removing the CMOS battery for 30 seconds
  • Some motherboards have specific USB ports that work during BIOS (usually the ports closest to the PS/2 port or the first two USB ports on the I/O panel). Try different ports if the keyboard does not respond at the BIOS screen
