I would advise you to update the BIOS and the touchpad driver in sequence for issue resolution. Please enter your service tag # on the link below, select the OS, then download the BIOS from BIOS section and touchpad driver from ‘Mouse, Keyboard & Input Devices’ section onto the system and install it.
I've updated the BIOS to A15 yet the problem still persists. Prior to updating the BIOS,i also had minor problems with my Intel Centrino N-2230 network card (which eventually disconnects from the network and fails to reconnect until after restarting the Laptop).But after updating it,it failed completely and i had to disable it,uninstall the driver,download the driver,reinstall it,before it responded again.Hope that will be a permanent solution. Now back to the touchpad scrolling gesture,it's still not working.i can now access the BIOS but there's very little one can do there as i don't see any settings fro the touchpad there. I've had an inspiron 1750 for 4 years now and it runs smoothly without any of such problems but the Inspiron 7720 is a complete headache. I'm now studying for my exams and i really do need the Inspiron 7720 to function fully.
As you are able to go into the BIOS, I would suggest that you run the diagnostics on the computer by following the steps mentioned below and check if there is any issue with the hardware on your system.
Turn on or restart the computer.
Immediately at the Dell logo screen, starting tapping the key once a second until the One Time Boot menu appears (if the computer boots to Windows turn the computer off and try again).
At the One Time Boot menu, press the arrow key to highlight Diagnostics, PSA+ or Enter ePSA, then press to begin the hardware Diagnostics.
Write down any error codes listed. Reply to us with the error codes.
