My top row of keys (function) seem to have either stopped working or changed function. Volume keys (F7 - F9) do not work. Brightness keys (F4 - F5) do not operate brightness but bring up the internet search box and page function, battery key (F3) moves cursor to Find field, Wi-Fi on/off (F2) and Screen selection (F1) appears to do nothing. F10 - F12 keys move the cursor around the screen and opens up a toolbar.
All other keys on the top row (other than Function) appear ok.
Welcome to Dell Community .I see that you are facing a issue with the keyboard .Please le us know if it is a notebook or a desktop you are using.
If it is a notebook ,try reunningthe complete diagnostic test .Either from the boot partition.You will need to tap F12 as soon as you press the power button.Else you can boot from the drivers Cd and run the specific test for the keybord.
If the system is a desktop,try using another USB/wireless keyboard.
Let me know the results.
Try going to Drivers & Downloads enter your service tag number, then select your operating system. Under applications, download and install Dell QuickSet and see if everything works again.
