HP Pavilion 15 EG3: Num Lock Not Working Fix
Intel Core i5-1335U • Windows 11 • Home Laptop
The HP Pavilion 15 EG3 includes a numeric keypad layout embedded in the right side of the keyboard with a Num Lock key. When Num Lock stops working — pressing the key has no effect, the indicator light does not change, or the numeric keys always type letters regardless of Num Lock state — one of the following steps resolves the issue.
Press Fn + Num Lock Check first
On the HP Pavilion 15 EG3, the Num Lock function may require pressing Fn + Num Lock rather than Num Lock alone. Try both combinations. Some Pavilion 15 keyboard configurations have Num Lock as a secondary function requiring the Fn modifier key to activate or deactivate.
Enable Num Lock at Boot via BIOS
Restart and press F10 to enter BIOS Setup. Navigate to System Configuration > Num-lock State or Boot > Num-lock. Set it to On. Some HP Pavilion BIOS settings boot with Num Lock disabled, which can also affect how Windows initializes the Num Lock state after startup.
Enable Num Lock via Registry at Login
Open Registry Editor and navigate to HKEY_USERS\.DEFAULT\Control Panel\Keyboard. Set InitialKeyboardIndicators to 2 (Num Lock on at boot). This ensures Num Lock is active every time Windows starts, preventing the default-off behavior that makes the numeric keypad unreliable after restarts.
Reinstall HP Keyboard Driver
Visit HP Support, search for the Pavilion 15 EG3 product number, and download the HP Keyboard and Hotkey driver. Install and restart. The HP keyboard driver manages Fn key secondary functions including Num Lock behavior on Pavilion models where Num Lock shares a key with another function.
“My Pavilion 15 EG3 Num Lock key did nothing after a Windows update. Setting InitialKeyboardIndicators to 2 in the registry fixed Num Lock persisting across restarts. The HP keyboard driver reinstall stopped the Fn key conflict.”

Why is Num Lock not working on the HP Pavilion 15 EG3?
On the HP Pavilion 15 EG3, Num Lock may require the Fn modifier key combination (Fn + Num Lock). Also check BIOS System Configuration for a Num Lock boot state setting and set it to On. For persistent Num Lock across restarts, set InitialKeyboardIndicators to 2 in the Windows registry at HKEY_USERS\.DEFAULT\Control Panel\Keyboard.
Does the HP Pavilion 15 EG3 have a numeric keypad?
Yes. The HP Pavilion 15 EG3 includes a full numeric keypad on the right side of the keyboard. The numeric keypad requires Num Lock to be active for the number keys to function. When Num Lock is off, the numeric keypad keys function as navigation keys (arrow keys, Home, End, Page Up, Page Down).
How do I make Num Lock turn on automatically at startup on the HP Pavilion 15 EG3?
Open Registry Editor and navigate to HKEY_USERS\.DEFAULT\Control Panel\Keyboard. Change the InitialKeyboardIndicators value to 2. This forces Windows to enable Num Lock at the login screen and maintains the Num Lock on state after sign-in. Some users may also need to set the same value under HKEY_CURRENT_USER\Control Panel\Keyboard.
Can a Windows Update disable Num Lock on the HP Pavilion 15 EG3?
Yes. Windows Update can reset the InitialKeyboardIndicators registry value or replace the HP keyboard driver with a generic HID driver that handles Fn key secondary functions differently. If Num Lock stopped working after a Windows Update, reinstall the HP keyboard driver from HP Support and verify the registry setting remains at 2.
