Persistent Numeric Keypad Malfunction - HP Laptop 15s-fq5330TU

[naveen457]

The numeric keypad on my laptop is not functioning correctly for data entry. Specificall

The keys only work as arrow functions/navigation keys in applications like Notepad and web forms.

The keys do work correctly for typing numbers when entering my Windows login password.but numers are not working at all any where.

This issue has been present since the initial purchase of the device.

Hi  @naveen457 
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand how this must feel, especially when the numeric keypad has not functioned correctly since the day you purchased the laptop, don’t worry let me check and help you with this. 

To better assist you, could you kindly confirm the below details : 

• Does the issue occur in all applications (Notepad, Excel, browser, etc.)?
• When you press the affected keys, do they always act as arrow/navigation keys?
• Does pressing the Num Lock key change the behaviour at all?
• Have you noticed any on-screen Num Lock indicator when toggling the key?

In the meantime, kindly try the below steps and confirm :  

Step 1: Enable/Disable Num Lock

1. Locate the Num Lock (NumLK) key on the keyboard.
2. Press it once and test the numeric keypad.
3. If available, try Fn + Num Lock.

Step 2:  Run HP Hardware Diagnostics (Link for steps - click here )

1. Turn off the laptop.
2. Power it on and repeatedly tap F2.
3. Select Component Tests > Keyboard.
4. Run the keyboard test and note any error messages.

Thank you for your response.

I have already performed all the checks and troubleshooting steps mentioned above, including the Num Lock/Fn + Num Lock tests and the HP Hardware Diagnostics keyboard test.

Here is what I observed:

- When Num Lock is OFF, the navigation keys work normally.

- When Num Lock is ON, the numeric keypad does not enter numbers, and the affected keys do not behave as expected.

- The issue occurs across applications such as Notepad, Excel, browsers, and other Windows applications.

- However, I don't believe this is a hardware issue because I have a dual-boot Ubuntu setup, and the numeric keypad works perfectly fine in Ubuntu.

- I can also enter numbers using the keypad during the Windows login screen.

- After logging in, I can sometimes enter numbers using the keypad in certain password prompts, such as when Chrome asks for a password for autofill.

- But once I am inside Windows, the numeric keypad does not work correctly in applications such as Notepad, Excel, or on websites.

This makes me suspect that the issue is related to Windows/application-level keyboard handling, a Windows service/setting, or a driver/software conflict, rather than a physical keyboard hardware problem.

I have already completed the hardware checks mentioned in your instructions. Could you please help me investigate the Windows-side issue, particularly why Num Lock works at the login screen and in some password prompts but not normally after logging into Windows?

Please let me know if there are any additional Windows-specific diagnostics or settings I should check.
