Hi there.

Product number : 4FG48UA

Windows 10 (64-bit)

I am currently utilizing an external keyboard to type this. On my HP Stream 14 laptop, these keys are unresponsive :

F10

F11

F12

So far I tried ;

1. Device Manager / Keyboard / Uninstall PS2 Keyboard / Restart - No luck

2. Start up menu / F10 / F5 / F10 / Restart - No luck

3. My drivers are up-to-date.

Is there anything else I can do? Thank you in advance.

Welcome to the HP Support Community.

Let's do keyboard test here:

1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Keyboard and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that. 

Let me know if this helps.
