How to Stop Your Wireless Keypad from Turning On NumLock Automatically

Are you frustrated with your wireless numeric keypad making letters type numbers? This common issue occurs when an external number pad activates NumLock, triggering your laptop’s hidden embedded numpad (where keys like U=4, I=5, J=1). In this guide, you’ll learn how to disable NumLock automatically when connecting your keypad, fix the letters vs numbers conflict, and keep your main keyboard working normally while using your external numeric pad. Perfect for users struggling with external keypad NumLock problems on Windows laptops from Dell, HP, Lenovo, and more.

Why This Happens

Your wireless keypad activates NumLock system-wide, enabling your laptop’s embedded numpad (hidden number layer on letter keys like U=4, I=5). Here’s how to fix it:

1. BIOS/UEFI Fix (Permanent Solution)

Restart computer and press BIOS key (F2/Del/Esc)
Navigate to Keyboard or Advanced Settings
Look for:
- Embedded Numpad
- NumPad Emulation
- Internal Keypad
Disable the setting

Not all BIOS versions have this option – check your manufacturer’s documentation.

2. AutoHotkey Script (Software Fix)

Steps to use:

Download AutoHotkey
Right-click desktop → New → AutoHotkey Script
Paste the code above and save
Double-click to run

3. Keypad Hardware Mode

Many keypads have hidden modes:

🔢 Numpad Mode: Requires NumLock (causes letter conflicts)
⌨️ Keyboard Mode: Sends standalone number keys

Check your keypad’s manual for a physical switch or key combo (often Fn+NumLock).

Pro Tip: Priority Fix Order

Try BIOS/UEFI setting first
Switch keypad to Keyboard Mode
Use AutoHotkey as last resort
