Hi OAKWINDS
Thanks for writing to us.
When did the issue start? Is it the first time you tried to turn off the touchpad?
Please update the touchpad drivers from support.euro.dell.com--enter tag #--submit--drivers and downloads--choose operating system--install as suggested.
Let us know how it goes.
Do provide us your system tag#, email address and name via private message,by clicking on my name in blue and then select send a private message
