Number Keypad Not Working in Windows 10? Fix It

If your number keypad (the separate block of digits on the right side of your keyboard) has stopped working in Windows 10, the most common cause is the Num Lock key being turned off, and pressing it once usually restores function. If that doesn’t work, the issue is often a Windows setting called “Mouse Keys,” a driver problem, or a hardware fault. This guide walks through each likely cause and the exact steps to fix them.

Why the Number Keypad Exists and How It Works

The number keypad (or numpad) is a compact 17-key block that speeds up data entry, especially for spreadsheets, calculators, and games. It was originally designed for accountants and data-entry clerks who needed to type numbers quickly with one hand. On a standard full-size keyboard, the numpad has its own Enter, Plus, Minus, and navigation keys (Home, End, Page Up, Page Down) that activate when Num Lock is on.

In Windows 10, the numpad’s behavior is controlled by the Num Lock toggle. When Num Lock is on, the keys type numbers. When it’s off, the same keys act as arrow keys and navigation shortcuts. Many keyboards have a small LED that shows whether Num Lock is active. If the keypad suddenly types numbers but then stops, or if pressing the keys moves the cursor instead of typing digits, Num Lock is almost certainly the culprit.

Quick Fix: Toggle Num Lock

The first thing to try is the simplest: press the Num Lock key (usually labeled “Num Lk” or “Num”) once. On most keyboards it’s located directly above the number 7 on the keypad. Look for the LED indicator – if it turns on, the keypad should work again. If you have a laptop without a dedicated Num Lock key, it’s often a secondary function on the F11 or F12 key, activated by holding the Fn key and pressing it.

If pressing Num Lock does nothing and the LED stays off, or if the keypad still doesn’t respond, move on to the next step.

Disable Mouse Keys (The Hidden Culprit)

Windows 10 has a feature called Mouse Keys that lets you control the mouse pointer with the number keypad. When enabled, the numpad keys (except 5) move the cursor instead of typing numbers. This feature can be turned on accidentally, often by pressing a keyboard shortcut or through a mis-click in Settings.

To disable Mouse Keys:

1. Open Settings (press Windows + I).
2. Go to Ease of Access > Mouse.
3. Under “Mouse Keys,” toggle the switch to Off.
4. Also uncheck the box that says “Use Mouse Keys when Num Lock is on” if it’s checked.

If you have a laptop, you can also try pressing Left Alt + Left Shift + Num Lock simultaneously – this is a shortcut that toggles Mouse Keys on and off. After disabling, test the keypad.

Update or Reinstall the Keyboard Driver

If the keypad still isn’t working, the driver might be outdated or corrupted. Windows 10 usually manages keyboard drivers automatically, but a bad update or a glitch can cause problems. To update the driver:

1. Right-click the Start button and select Device Manager.
2. Expand Keyboards.
3. Right-click your keyboard device (often “Standard PS/2 Keyboard” or a specific model name) and select Update driver.
4. Choose Search automatically for drivers. If Windows finds nothing, try the next step.

If updating doesn’t help, uninstall the driver and restart your PC. Windows will reinstall it automatically on boot. To uninstall, right-click the keyboard in Device Manager and select Uninstall device, then restart. This often clears glitches that a simple update can’t fix.

Check for Hardware Issues

If the keypad still doesn’t respond, the problem may be physical. Try these checks:

• Plug the keyboard into a different USB port. Sometimes a port loses power or has a bad connection.
• Test the keyboard on another computer. If the numpad fails there too, the keyboard is likely faulty.
• For laptops, check if the numpad is a separate physical block. Some compact laptops don’t have a dedicated numpad at all – they use a hidden overlay on the letter keys (often activated by holding Fn). If your laptop lacks a physical numpad, the “number keypad not working” may actually be a misunderstanding of the layout.
• Clean the keys. Dust or debris can cause keys to stick or not register. Turn off the computer, gently remove the keycaps (if possible), and blow out any particles.

If the keyboard is wireless, replace the batteries and re-pair it. Low battery power can cause erratic behavior, including dead keys.

Use the On-Screen Keyboard as a Temporary Workaround

While you troubleshoot, you can still enter numbers using the On-Screen Keyboard built into Windows 10. To open it:

1. Press Windows + R, type osk, and press Enter.
2. Click the Num Lock button on the on-screen keyboard (it’s labeled “Num Lk” on the bottom-right).
3. Click the number keys you need.

This is a temporary fix, but it lets you keep working while you resolve the hardware or software issue.

Frequently Asked Questions

Why does my number keypad work but types letters instead of numbers?

That happens when Num Lock is off. When Num Lock is disabled, the keypad acts as navigation keys (arrows, Home, End, etc.) instead of typing digits. Press Num Lock to toggle it back on. Some keyboards require you to hold the Fn key while pressing Num Lock, especially on laptops.

My Num Lock key doesn’t seem to do anything. What else can I try?

If pressing Num Lock has no effect, check if Mouse Keys is enabled (see the section above). Also, try using the on-screen keyboard to toggle Num Lock – click the “Num Lk” button there. If that works, your physical Num Lock key may be faulty, and you can use the on-screen keyboard as a workaround.

Is there a way to make the number keypad always work without pressing Num Lock?

You can change the default Num Lock state in the BIOS/UEFI settings. Restart your computer, press the key to enter setup (usually Del, F2, or F10), and look for “Num Lock State” or “Boot Num Lock” – set it to “On.” Note that this changes the default for when the computer boots, but you can still toggle it manually.

Why does my number keypad work in some programs but not others?

This is usually because the program uses the numpad for shortcuts or navigation. For example, in some games, the numpad keys are mapped to actions. In Excel, the numpad works normally, but in some text editors, it might be used for macros. Check the program’s settings or shortcuts to see if it’s overriding the default behavior.

Can a Windows update cause the number keypad to stop working?

Yes, a Windows update can occasionally break keyboard drivers or change settings. If the keypad stopped working right after an update, try rolling back the driver (in Device Manager, right-click the keyboard, go to Properties > Driver > Roll Back Driver) or run Windows Update to see if a new fix is available.

Should I buy a new keyboard if the numpad is still dead?

If you’ve tried all the software fixes and tested the keyboard on another computer with the same result, the keyboard is likely physically damaged. In that case, replacing it is the most practical solution. If it’s a laptop, you can use an external USB keyboard with a numpad as a cheaper alternative to a motherboard repair.
