To resolve the keyboard issue on your HP laptop, here are some steps you can try, including working around the BIOS update challenge:
Check under the laptop or battery compartment for labels.
Open Command Prompt and run:
wmic bios get serialnumber
Or use HP Support Assistant to find the model and serial number.
Power off the laptop, disconnect peripherals, and remove the battery (if possible).
Hold the power button for 15-30 seconds.
Reinsert the battery and restart the laptop.
Visit HP Support, enter your serial/model number, and download the BIOS update.
Run the update utility while plugged in.
If HP doesn’t recognize your laptop, try the HP Product Detection Tool.
Restart the laptop and press F10 to enter the BIOS menu.
Select Reset to Default Settings, save, and exit.
Open Device Manager > Keyboards > Right-click your keyboard > Properties.
Uncheck "Allow the computer to turn off this device" under the Power Management tab.
Open Settings > Update & Security > Recovery > Advanced Startup.
Restart and select Troubleshoot > Advanced Options > Startup Settings > Restart.
Press F4 to enter Safe Mode and test the keyboard.
