Honam 1021, I would start off with a Driver update. You can check the ones [http://www.dell.com/support/drivers/us/en/04|on here.] If that does not help, you might need to replace the keyboard. It is not a bad task and the service manual is available [http://support.dell.com/support/edocs/systems/ins600m/en/sm/index.htm|right here.] Hope this helps, good luck.
