Laptop Keyboard Not Working? 9 Fixes That Work (Windows 11)

If your laptop keyboard stopped working in Windows 11, start with the free, quick checks: restart with every accessory unplugged, turn off Filter Keys (hold the right Shift key for eight seconds, or go to Settings > Accessibility > Keyboard), check Num Lock and Fn Lock, then reinstall the keyboard driver in Device Manager. If the keys still do nothing inside the BIOS/UEFI setup screen or in the manufacturer’s hardware test, the problem is the keyboard itself, not Windows.

The nine fixes below are ordered from fastest to most involved. Every menu path was checked against Microsoft, Dell, HP and Lenovo documentation.

Before you start: how to type while the keyboard is dead

Two tools let you type and show whether the problem is the keyboard or Windows:

• On-Screen Keyboard. Using the touchpad, go to Start > Settings > Accessibility > Keyboard and turn on the On-Screen Keyboard toggle. On the sign-in screen, use the Accessibility button in the lower-right corner. The shortcut is Windows + Ctrl + O, but that only helps if some keys still respond.
• An external USB keyboard. If it types normally, the trouble sits in the built-in keyboard or its driver. If it also fails, focus on Windows settings (Fixes 2 to 6). Any basic wired USB keyboard is enough for this test.

If the touchpad is also unresponsive, the cause is more likely system-wide; our guide to a Dell laptop mouse or touchpad that stops working covers that side.

Fix 1: Restart with all accessories unplugged

Dell’s own first step is to disconnect USB devices, external monitors and docking stations, then restart. A stuck dock, KVM switch or gaming-keyboard utility can grab keyboard input.

1. Save your work and unplug everything except the charger.
2. Restart from Start > Power > Restart using the touchpad.
3. Test the keyboard in Notepad. If it works, reconnect devices one at a time to find the culprit.

If keys fail in only one app, that app is the problem. Macro tools and KVM software are worth uninstalling as a test.

Fix 2: Turn off Filter Keys (and Sticky Keys)

Filter Keys tells Windows to ignore brief or repeated keystrokes. With it on, quick taps simply don’t register, so the keyboard looks dead. It’s easy to turn on by accident: holding the right Shift key for eight seconds toggles it.

1. Press Windows + U, or go to Start > Settings > Accessibility.
2. Select Keyboard.
3. Turn off Filter keys. While you’re there, also turn off Sticky keys if modifier keys behave oddly.

Microsoft lists all of these toggles on its Windows accessibility keyboard shortcuts page.

Fix 3: Check Num Lock and Fn Lock

Num Lock

On compact laptops without a separate number pad, some letter keys double as numbers. With Num Lock on, those letters type digits. Press Num Lock (on some models Fn + Num Lock) and test again. If your laptop has no Num Lock light, turn on Toggle Keys in Settings > Accessibility > Keyboard so Windows plays a sound whenever you press Caps Lock, Num Lock or Scroll Lock.

Fn Lock

Fn Lock swaps the top row between F1-F12 and media actions (volume, brightness). If F5 suddenly changes the brightness instead of refreshing a page, Fn Lock flipped.

• Dell: hold Fn and press Esc. Repeat to switch back. The default is also set in BIOS (F2 at startup) under Post Behavior > Fn Lock Options on newer BIOS screens, or Advanced > Function Key Behavior on tabbed ones.
• Lenovo: on many IdeaPad, Yoga and LOQ models, Fn + Esc turns FnLock on and off, and a small LED shows its status.
• HP: the method depends on the model. HP keeps a dedicated support article, “HP Notebook PCs – How to lock or unlock the fn (function) key,” so search that title with your model number.

Fix 4: Make sure the keyboard layout is correct

If keys work but print the wrong characters (Y and Z swapped, symbols in odd places), Windows is using a different layout. Windows + Spacebar cycles through installed layouts, so it’s easy to switch by accident.

1. Go to Start > Settings > Time & language > Language & region.
2. Next to your language, select the three dots, then Language options.
3. Under Keyboards, keep “US” (or your real layout) and remove the ones you don’t use.

Fix 5: Reinstall the keyboard driver in Device Manager

A corrupted driver can make the built-in keyboard stop responding. Reinstalling it only needs the touchpad.

1. Right-click Start and select Device Manager.
2. Expand Keyboards.
3. Right-click each entry listed there and select Uninstall device, then confirm with Uninstall.
4. Restart from the Start menu. Windows reinstalls the driver automatically at boot.

You can also right-click the entry, choose Update driver and let Windows search automatically. Microsoft’s Device Manager driver guide walks through both options.

Fix 6: Install pending driver and BIOS updates

Optional driver updates aren’t installed automatically. Go to Settings > Windows Update > Advanced options > Optional updates, select any driver updates and choose Download and install, then restart.

Dell lists a BIOS update among its keyboard fixes. Use the maker’s own tool: SupportAssist on Dell (Home tab, Update Software), or the drivers page for your exact model on HP and Lenovo. If the same laptop is also losing charge quickly, our guide to a laptop battery draining fast in Windows 11 covers the power side.

Fix 7: Test the keyboard outside Windows (BIOS/UEFI and diagnostics)

This step settles software vs. hardware. If the keys work before Windows loads, the keyboard is fine.

• Any Windows 11 laptop: go to Settings > System > Recovery, select Restart now next to Advanced startup, then Troubleshoot > Advanced options > UEFI Firmware Settings > Restart. Once in the setup screen, try moving with the arrow keys. Exit without saving changes.
• Dell: tap F12 at the Dell logo, choose Diagnostics from the One Time Boot Menu. SupportAssist in Windows also has a keyboard test.
• HP: turn the laptop on, press Esc about once per second until the startup menu appears, then press F2 to open HP PC Hardware Diagnostics UEFI. Under Component Tests there is an interactive keyboard test.
• Lenovo: the BIOS key varies by model, so the Windows 11 route above is the most reliable. Our guide to changing RAM speed in the BIOS on Lenovo laptops deals with the same setup screen.

Keys that are dead in BIOS and in the diagnostic tool point to hardware: a cable, liquid damage or a failed keyboard.

Fix 8: Clean under the keys

If only a few keys stick or need extra force, debris is the usual cause.

1. Shut down the laptop and unplug it.
2. Blow around the affected keys with canned compressed air. Dell’s guidance is to keep the can upright, never tilted or upside down.
3. Wipe the keys with a microfiber cloth. For sticky residue, use a swab barely dampened with isopropyl alcohol and let it evaporate before powering on.

Avoid prying keycaps off: Dell notes that if the small scissor spring under a key is damaged, that keycap can’t be reattached. Our step-by-step on cleaning a laptop keyboard from dust and dirt goes deeper, and if dust is also why your laptop fan is always running or loud, keep that can of air nearby.

Fix 9: If you spilled liquid on the keyboard

Act fast. Dell’s advice:

1. Turn the laptop off immediately and unplug the charger.
2. Tilt it to drain as much liquid as possible.
3. Wipe it with a soft microfiber cloth.
4. Let it dry for at least 24 to 48 hours in a warm, dry place before turning it on.

If keys still misbehave once it’s fully dry, have it inspected rather than keep using it.

When it’s a hardware problem

It’s hardware if the keys fail in BIOS or in the maker’s keyboard test. Your options:

• Warranty first. Check coverage on the maker’s support site with your serial number or service tag. If you’re thinking about opening it yourself, read whether opening a Lenovo laptop voids the warranty first.
• Know what gets replaced. The keyboard isn’t always a separate part: Dell’s service manual for the Inspiron 15 3520, for example, lists a combined palm-rest and keyboard assembly.
• Keep working meanwhile. An external keyboard is a cheap stopgap.

FAQ

Why did my laptop keyboard suddenly stop working?

Common software causes are Filter Keys turned on by holding the right Shift key, Num Lock or Fn Lock changing what keys do, a corrupted driver, or a dock or utility grabbing input. Physical causes are debris, liquid and a failing keyboard.

How do I unlock a locked laptop keyboard?

What feels like a locked keyboard is usually Filter Keys (turn it off in Settings > Accessibility > Keyboard), Num Lock, or Fn Lock (Fn + Esc on many Dell and Lenovo models).

Why do some keys type numbers instead of letters?

Num Lock is on. On laptops where some letter keys double as numbers, Num Lock switches them. Press Num Lock (or Fn + Num Lock on some models) to turn it off.

How can I tell if my laptop keyboard is broken?

Enter the BIOS/UEFI setup or run the maker’s diagnostics (F12 on Dell, Esc then F2 on HP). If the keys fail there too, no Windows setting will fix it.
