A laptop keyboard can stop working because of a temporary Windows problem, disabled keyboard settings, outdated or corrupted drivers, dirt under the keys, a stuck key, a recent update, or physical damage. Try these solutions in order, starting with the easiest.

✅ Common Signs of a Laptop Keyboard Problem

• None of the keys work
• Only some keys work
• Certain letters or numbers don’t type
• Keyboard works intermittently
• Keys type the wrong characters
• Keyboard stopped working after a Windows update
• Keyboard doesn’t work on the Windows login screen
• External USB keyboard works but the built-in keyboard doesn’t

🛠️ Things You’ll Need

✔ Laptop charger
✔ Soft brush or compressed air
✔ USB keyboard, if available
✔ Mouse or touchpad
✔ Internet connection for driver updates

⚠️ Before You Start

If liquid was recently spilled on the keyboard, turn the laptop off immediately, disconnect the charger, and don’t continue using it. Liquid damage can cause short circuits and corrosion, and professional inspection may be necessary.

Don’t force stuck keys or spray liquid directly onto the keyboard.

🔧 Step-by-Step Keyboard Not Working Fix

1️⃣ Restart the Laptop

A temporary Windows or driver problem may stop keyboard input.

1. Save your work if possible.
2. Open the Start menu.
3. Select Power → Restart.
4. Test the keyboard after Windows loads.

If the keyboard works again, the issue may have been temporary.

2️⃣ Check Whether the Problem Affects All Keys

Try several different keys:

• Letters
• Numbers
• Enter
• Spacebar
• Shift
• Ctrl
• Arrow keys

If only a few keys are affected, physical damage or debris may be more likely.

If every key has stopped working, software, drivers, or hardware connections become more likely suspects.

3️⃣ Check Num Lock and Function Lock

Some laptops have special keyboard modes controlled by Fn keys.

Try:

• Num Lock
• Fn + Num Lock
• Fn + Esc
• The manufacturer’s keyboard-lock shortcut

The exact combination varies by laptop model.

If letters are producing numbers or certain keys behave unexpectedly, Num Lock or another keyboard mode may be enabled.

4️⃣ Check the Windows Keyboard Layout

If the keyboard works but produces unexpected characters, the problem may be the keyboard layout rather than the hardware.

Go to:

Settings → Time & language → Language & region

Check the installed keyboard layout and select the one you normally use.

5️⃣ Turn Off Filter Keys

Windows accessibility settings can affect how keyboard input is handled.

Go to:

Settings → Accessibility → Keyboard

Check Filter Keys and turn it off if you don’t need it.

Then test the keyboard again.

6️⃣ Try the On-Screen Keyboard

If the physical keyboard isn’t working, you can use the Windows On-Screen Keyboard to navigate the system.

Go to:

Settings → Accessibility → Keyboard → On-Screen Keyboard

This can also help you access Windows while troubleshooting the physical keyboard.

7️⃣ Test an External USB Keyboard

Connect a USB keyboard to the laptop.

If the USB keyboard works:

Windows is probably receiving keyboard input correctly, so the problem may be related to:

• Built-in keyboard hardware
• Keyboard cable
• Keyboard connector
• Laptop keyboard assembly

If the USB keyboard also doesn’t work:

The problem may involve Windows, drivers, system settings, or a broader hardware issue.

8️⃣ Update the Keyboard Driver

A corrupted or outdated driver can cause keyboard problems.

Steps:

1. Right-click Start.
2. Select Device Manager.
3. Expand Keyboards.
4. Right-click the relevant keyboard device.
5. Select Update driver.
6. Choose the available automatic search option.

Restart the laptop afterward.

9️⃣ Reinstall the Keyboard Driver

If updating doesn’t help, reinstalling the keyboard device can force Windows to reload its driver.

Steps:

1. Open Device Manager.
2. Expand Keyboards.
3. Right-click the affected keyboard.
4. Select Uninstall device.
5. Confirm the removal.
6. Restart the laptop.

Windows will normally detect the keyboard again during startup.

🔟 Check for Windows Updates

If the keyboard stopped working after a recent Windows change, check for available updates.

Go to:

Settings → Windows Update

Install appropriate updates and restart the laptop.

If the problem started immediately after a specific update, Windows Recovery options may also provide ways to uninstall the recent update.

🧹 11️⃣ Clean the Keyboard

Dust, crumbs, and other debris can prevent individual keys from working.

Safe approach:

1. Turn off the laptop.
2. Disconnect the charger.
3. Hold the laptop at an angle.
4. Use compressed air according to the manufacturer’s guidance.
5. Gently brush away visible debris.

Don’t pour or spray cleaning liquid directly onto the keyboard.

If a key remains stuck, don’t pry it off unless you know the correct removal procedure for your laptop model.

🔍 12️⃣ Check for Physical Damage

Inspect the keyboard for:

• Cracked keys
• Missing keycaps
• Bent areas
• Liquid stains
• Swelling near the keyboard
• Keys that feel different from others

If the laptop has been dropped or liquid was spilled on it, the internal keyboard connection or keyboard assembly may be damaged.

🖥️ 13️⃣ Test the Keyboard Before Windows Loads

This can help distinguish a Windows problem from a hardware problem.

Restart the laptop and try entering the BIOS/UEFI setup using the manufacturer’s designated key, often F2, Delete, Esc, or F10.

If the keyboard works in BIOS/UEFI:

The hardware may be functioning, and Windows/software troubleshooting is more relevant.

If the built-in keyboard doesn’t work even in BIOS/UEFI:

A hardware issue becomes more likely.

The exact BIOS key varies by manufacturer.

🔧 14️⃣ Check the Keyboard Connection

On some laptops, the keyboard connects to the motherboard using a thin ribbon cable.

If the keyboard stopped working after:

• Laptop repair
• Keyboard replacement
• Cleaning
• A drop

the cable or connector may have been disturbed.

Opening a laptop can damage delicate components or affect warranty coverage, so unless you’re experienced with laptop repair, professional service is safer.

🔄 15️⃣ Use System Restore if the Problem Started Recently

If the keyboard worked normally before a recent software change and System Restore is available, you may be able to restore Windows to an earlier state.

Search Windows for:

Create a restore point → System Restore

Choose an appropriate restore point from before the problem began.

🚨 When to Call a Professional

Professional repair is recommended if:

• The keyboard doesn’t work in BIOS/UEFI.
• Liquid was spilled on the laptop.
• The laptop was dropped.
• Multiple keys are physically damaged.
• The keyboard connector may be damaged.
• A replacement keyboard is required.
• The laptop shows signs of internal damage.

If liquid exposure occurred recently, don’t repeatedly power the laptop on to test it.

⭐ Prevention Tips

✔ Keep food and drinks away from the laptop.
✔ Clean the keyboard regularly.
✔ Avoid pressing keys excessively hard.
✔ Keep Windows and drivers updated.
✔ Use a protective laptop sleeve when transporting the computer.
✔ Don’t use liquids directly on the keyboard.

❓ Frequently Asked Questions

Why is my laptop keyboard not typing?

Common causes include Windows glitches, keyboard settings, driver problems, debris, physical damage, or a disconnected keyboard cable.

What if only some keyboard keys don’t work?

If only specific keys fail, check for dirt or physical damage. If cleaning doesn’t help, the keyboard assembly may need repair or replacement.

Why does my USB keyboard work but my laptop keyboard doesn’t?

This usually suggests that Windows is capable of receiving keyboard input and the built-in keyboard, its connection, or its related hardware may be the problem.

How do I fix a keyboard that stopped working after an update?

Restart first, then check keyboard drivers and Windows Update. If the issue began immediately after a specific update, consider using an appropriate Windows recovery option to roll it back.

Can I fix a laptop keyboard myself?

Software problems and basic cleaning are often suitable DIY tasks. Internal keyboard replacement or connector repair is more complicated and may be better handled by a qualified technician.

✅ Final Words

A laptop keyboard that isn’t working doesn’t always mean the keyboard needs replacement. Start with a restart, check keyboard settings and Num Lock, test an external keyboard, and then troubleshoot the keyboard driver.

If the keyboard doesn’t work even in BIOS/UEFI, or the laptop has suffered liquid or physical damage, the problem is more likely hardware-related.

For a damaged keyboard or internal connector, professional repair is usually the safest option.
