Question about Computers & Internet
If some keys are not working check in safe mode whether they are working..
To get into safe mode keep pressing the F8 key on the keyboard while the system turns on in the Dell screen....
If the keyboard works in the safe modem then install a fresh copy of drivers for the keyboard(www.support.dell.com)..
If the keyboard is not working in the safe mode then call dell(18006249896) or a local tech and get the keyboard replaced...

You just need a new keyboard - those are easy to come by check ebay.com and search for C640 keyboard. New ones should only be about $30-$40.
To remove the keyboard you just remove all the screws on the bottom of the laptop that are marked with the letter "K" then carefully pop the keyboard up.
Let us know if you need further help!
