Is there an easy way to turn the touchpad on/off? Is there (or can there be) a button that will easily do this? Can I reprogram a function key (F12) with a macro that will do this? If so, what is the macro
As I Understand you need information on an easy way to turn off the touchpad temporarily,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Is there any particular reason you would want to turn off the touchpad?
Did you check the Synaptics touchpad settings on your PC to make these changes?
While you respond to that, follow the below steps and you'll be good to go
1. On some touchpads, you can turn on or off the Touchpad by double tapping in the upper left corner of the Touchpad. Double tap to turn the Touchpad on, repeat to turn the Touchpad off.

2. Perform a hard reset by following the steps in the HP document Performing a Hard Reset or Forced Reset (in English). A hard reset clears the driver instructions. Your computer re-reads all instructions from the drivers and software stored in the Operating System which can solve some problems.
3. Be sure you have the latest drivers for your Touchpad. Use the following steps to install the latest drivers.
