some function keys are not working like f1

Hi,

Welcome to the Community. 

I would suggest you to run a custom test on the keyboard using the Drivers and Utilities disk sent with the system. Steps on how to run custom scan are mentioned below:

1. Insert the disk of Drivers and Utilities in the computer
2. Unplug all external peripherals except the power cord
3. Turn of the computer
4. Restart the computer and the moment it starts start tapping the F12 key to boot the computer to One Time Boot Menu
5. Highlight CD/DVD/CD-RW Drive ad hit Enter
6. Press Enter again if it shows “Press any key to boot from CD”
7. Select Custom Scan and run the test on the keyboard.

If the F12 key does not boot the computer to One Time Boot Menu, keypad needs to be replaced. In case, it does check all the keys on the test. If the keys don’t work on the test the keyboard need to be replaced.

If all the keys are functional during the test, uninstall or disable any software that may change how the keyboard operates. This software includes:

• Keyboard macro programs

• External keyboard drivers

• KVM (keyboard, video, mouse) switch software

Also, would recommend you to update Quickset driver of the system. Please click on the link below which will take you to the driver’s website: http://dell.to/uIo3ef

Enter the Service Tag of the computer and choose the Operating System installed on the computer. Please select application, under application select the latest version of Dell-Application driver available.

Please keep me posted with the results.

Thanks & Regards
