M3800 touch-pad issue after windows 10 auto-update
My Laptop touch pad stop working after critical update, I uninstalled the update but issue came back after few days and window update itself automatically. I tried installing generic synaptic driver that did not update the mouse driver, tried force update after extracting driver in a file, it also did not work. Finally I reinstall the BIO A10. Although I had same BIOS but it flash it again, and then reinstall the latest same touch pad driver from dell support side that was issued some time time 2015. Wasted 4 days and was ready to through out laptop off windows. Hope it help and save some time anyone one who has issue. Dell support is pathetic in this regard.
