I have a recently acquired XPS 15 running Windows 10.
The touchpad is set to 'tap to click', but at random intervals (usually after the computer has been on for 24+ hours), it stops working. The first tap still registers as a click, but it gets stuck, and does not release when one removes one's thumb from the touchpad, so that it is necessary to use the button to click instead.
This doesn't seem to have anything to do with Windows settings, as 'tap to click' is still switched on in the mouse settings. Nor is it a hardware issue, because restarting the machine causes it to return to normal. My guess is that it has something to do with the touchpad drivers (?), in which case, why has Dell not rectified this issue? Is there a solution?
(I couldn't find another thread on the subject in this forum, but there are others out there on the internet.)
RE: Tap to click stops working periodically (XPS 15)
If the driver were at fault, "Tap to click" would simply never work. This sounds more like an operating system resource issue. A simple check for this, don't leave it running for 24 hours. Restart the computer at least twice in a 24 hour period.
