Heya - I've been at this for hours and have read so many of these posts I think I'll do my part...
I have a dell latitude d610 on xp pro - after using driverrobot to do a full system driver update (highly recomended though regardless of the ensuing problem I think - solution below) my ALPS touchpad buttons stopped working - I figured twas a driver issue right, so I tried updating/reinstalling through windows and through the dell site, and same thing - the touchpad could tap and double-click, but could not drag icons or drag-highlight icons, and the buttons didn't work (even though in the mouse properties it had the right settings. After just resorting to uninstalling the ALPS device itself from the device manager list I noticed the touchpad function would return to normal, only to revert back to semi-functional after windows rebooted, detected 'new hardware' and 'fixed' the issue by re-installing the touchpad.
Solution (worked for me:) Whatever I tried nothing changed, so I went into add/remove programs (in control panel) and found the ALPS touchpad pointing-device program. After removing that - all good. I'm assuming it was a seperate program to control touchpad functions - after that the little pad usually by the clock that changes colour to show touchpad activity was gone. What a bloody mission, but another God-damned windows problem bites the dust... Anyway hope it helps someone out there! :)
I found out upon updating Win 8 to Win 10, my USB Root Hub was disabled. This turned off my webcam and usb ports, among others. If driver updates don't help and the devices are shown when you toggle "show hidden devices" in device manager, you might need a troubleshoot to re-enable your usb hub! Hope it helps...I was looking for hours thinking it was a driver issue.
Hi, I had a similar problem with my Lenovo Z510 after I updated it from windows 8 to windows 10. There was a error cropping up when the PC would start. "Alps Set Mouse Monitor Error"
I solved it by doing a Boot time scan from the Quick Heal Total security. It worked.
I too have been dealing with touchpad randomly shutting off on Dell Insprion laptop with windows 10. Searching through device manager and mouse settings showed nothing for touchpad, and no dirvers found on Dell Support site either.
Instead what I discovered after much searching, is that there is a setting for turning touchpad on/off hidden in the windows settings. Open up Settings in the Start menu, then search for Windows Mobility Center. Click to open. You will find settings for both Touchpad on/off and Function key behaviour there.
I have read of some laptops with Fn keys that toggle touchpad settings. Hence I've changed my laptop so Fn keys behave as function keys, not multimedia.
