Sometimes my Surface Pro 4 touchpad stops working when I resume from sleep. The keys on the type cover still work, just no responsiveness from the touchpad.

Microsoft support recommends reattaching the cover, getting the latest updates (have them), or restarting the machine.

Restarting usually does the trick, but it's obviously very annoying to do so. Is there some way I can get it to recognize the touchpad again without a full restart? Maybe some trickery in the device manager or the registry?

    If their suggestion does not work I suggest a warranty claim – Ramhound Nov 14 '15 at 22:49

A large class of device enumeration problems can be recovered from by cycling through "Disable"/"Enable" on the device in Device Manager. (Although this may by more annoying than detaching/reattaching the keyboard/touchpad). This can be done from a command line script if you are willing to install DevCon: https://msdn.microsoft.com/en-us/library/windows/hardware/ff544707(v=vs.85).aspx

  • I don't understand why you would say that adding another option likely to achieve what the user wants (with its own associated pros and cons), that the user had not considered, is not an answer. Specifically go to Device Manager, click on the device, disable it, wait until its done, enable it. (I have since learned of DevCon which can probably do this from a script.) In fact, the user invited a solution involving "trickery" and Device Manager, which is exactly what I suggest. – Mike Layton Aug 22 '16 at 23:50
  • Maybe you assumed that this was the same as detaching/reattaching. I believe that (in this context) is referring to mechanically and electrically separating the tablet CPU from the optional keyboard, and then reattaching. – Mike Layton Aug 22 '16 at 23:54
  • No, my comment was related to 1/ "You can probably". and 2/ "I'd look into whether this can be done from a command line script" Something which implies you are not sure does not make a good answer. – DavidPostill Aug 23 '16 at 7:23

    I wonder if you will find my edits satisfying now. But note: you are not improving the quality of answers by encouraging them to be written with overconfidence. Do you verify that those who "are sure" are justifiably sure? – Mike Layton Aug 24 '16 at 0:26
