Hi @Brammi,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand your HP 14s fq1xxx laptop's keyboard backlight and some keys are not functioning after a recent update. You can try the following troubleshooting steps to resolve the issue:
 

Check Keyboard Backlight Settings:
 

• Use the keyboard function key combination (usually Fn + Backlight key) to toggle the backlight. Verify if it is enabled.

Examine Physical Connections:
 

• Check if there's any visible debris under the keys or if any keys feel loose.
• Gently clean the keyboard using compressed air to remove dust that may be obstructing key function.

Device Manager Check:
 

• Open Device Manager on your computer.
• Under the Keyboards section, ensure the keyboard is recognized without errors (no yellow or red markings).

Update Keyboard Driver:
 

• Update drivers via Device Manager:
  • Right-click on the keyboard device and select Update driver.
  • Choose to search automatically for updated driver software.

Check Keyboard and BIOS Settings:
 

• Even though your BIOS is up-to-date, double-check keyboard-related settings in the BIOS:
  • Enter BIOS setup (usually by pressing F10, F2, or Esc during startup).
  • Look for keyboard backlight settings and ensure they are set correctly.

HP Support Assistant:
 

• Use the HP Support Assistant tool to diagnose and obtain any additional updates that may not have been applied:
  • Open HP Support Assistant and check for any alerts or updates related to your keyboard.

Perform a Hard Reset:
 

• Power off the laptop.
• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for approximately 15 seconds.
• Reconnect the power adapter and battery, then power on the laptop.

Advanced Diagnostics:
 

• Use HP PC Hardware Diagnostics to perform component tests on the keyboard:
  • Restart the laptop and press F2 repeatedly to access the diagnostics tool.
  • Run the keyboard test to identify any specific hardware issues.
    
    
    I hope this helps.

Take care and have an amazing day!
