Keyboard stops working by Wificard

[Saafism]

My laptop's keyboard is not working and I was using external keyboard. And I accidentally found that laptop's keyboard starts working when the flight mode is on. I thought of changing the Wi-Fi card. Even after changing the Wi-Fi card, problem was not solved. The moment I insert the Wi-Fi card the keyboard stops working. Please note that only keyboard is not working but mouse pad is still working. What could be the problem?

@Saafism, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check Device Manager for Conflicts

Boot with the external keyboard and Wi-Fi card installed.

Go to Device Manager.

Check for:

Yellow exclamation marks under Keyboards, Network adapters, or System devices.

See if the internal keyboard is recognized at all.

If not listed → it’s either disabled or not being detected due to a hardware issue.

Try a Different Wi-Fi Card (Different Model)

Try using a different model or brand of Wi-Fi card (ideally a known compatible one).

Check BIOS/UEFI Settings

Enter BIOS.

Look for:

Internal Device Configuration – ensure keyboard is enabled.

Resource configuration / IRQ settings (if available).

Try disabling Advanced Power Management or ACPI temporarily to see if it changes behavior.

Also:

Check BIOS version.

If outdated → update to latest version from the manufacturer’s site.

I hope this helps.
