I have had my Dell Inspiron 7559 for about a week now, it runs windows 10. Over the past few days the trackpad has started to not work. At first the single tap (left click) didn't work. But the left click button worked fine and the two tap (right click) worked fine too. I restarted it, single tap works again.
This happened a couple more times and I decided to investigate. There was no touchpad on my mouse settings, only a HID-compliant mouse and a PS/2 Compatible Mouse. I don't have any mice. I did a driver update for both of the above and ELAN input device showed up. I did a driver update for it and it worked ok for a couple of hours and it said it is working properly. However if stopped working again and I went back to the settings and whilst windows 10 settings said the trackpad was on, the ELAN tab on the mouse properties said that the Elan smart-pad was not enabled it and restarted. When I went back to the same settings after the restart, it was not enabled again. So I enabled it. Two hours later, the trackpad was back to not registering single taps. Enabling and disabling the ELAN trackpad appears to do nothing.
The next day, single tap stopped working and then all the buttons and taps stopped working but scroll/zoom etc still worked. I restarted and it worked again. Later on it had the issue that the trackpad would only select things on the start bar. Once you opened something you couldn't click at all. Again I restarted and it "fixed" it.
I don't know what to do next. Any advice?
No suggestions? I bought a mouse because it was getting annoying. However sometimes when the trackpad stops working the mouse does too. You can still see the cursor move around but clicking doesn't work.
What is the current OS version installed on the system? What applications are you using when the touchpad stops responding? After you power on the system, how long does it take before the touchpad stops working?
Update the BIOS - http://dell.to/2aV8Rib - and reinstall the touchpad drivers and check.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.
Also, run a custom test on the touchpad through Support Assist - http://dell.to/1NEc1Y4
Restart the system and check in safe mode - http://bit.ly/1LHcO2c
Create a local admin account and check if it works fine - http://bit.ly/1JoFhcw
If nothing works, then backup your data and perform a factory reset - http://dell.to/1XZvpiw
