Dell does not even include a flash drive(or DVD) any longer for repair or restore of the OS or drivers and software ioncluded in the original unit. Just the Exact copy of the OS on a recovery partition. I have an exact copy of the original operating system that I always make with brand new computers before I use them or load any software into them but have no idea what the driver name would be. 1: I have Dell auto update enabled and check it to be sure I am up to date. 2: Yes I have been to dell support several times since this started and their detection utility also says I am up to date with one exception. I also ran their complete diagnostics utility and every thing passed. I did install a bios update which was available(not rated vital). Auto update had not installed it even though it had been available for 2 months. No changes after the install. The issue was still there. An Intel chipset driver update is failing to install. I did some reading in their support forum and may need to extract the contents to another folder within that folder to get it to install. The package gives you two choices, extract and install. It was supposed to auto install. Tried both options. Even downloaded it a second time. There has not been a whole new bios update yet. I did not check the hash to verify it as a good download. Dell lists the values for all their downloads. I also tried their option to find the touchpad driver myself and found a lot of drivers for touchpads/keyboards but none for Inspiron Laptops. Tried a specific search for it as well as a search for all drivers for my specific model. I had a year of premium support which ran out two months ago. I contacted Dell about extending it so I can get phone support for this. Kind of thought thru their support forum or Tenforums/Tom's Hardware that I could find this out but no luck so far. Even if it is a dell driver it has to be approved/signed by microsoft for a vendor to use it with windows. I suspect it is the driver but their is no option to roll back the driver and with CU in place I doubt I can restore back far enough to see if their was a dell driver for the touchpad. There are a lot of touchpad issues out there in many brands of laptops and in Win 8.1 and Win 10. I have a touchscreen as well and some forums say it can cause issues too. Other companies say they have the driver I need but I prefer not to trust drivers other than manufacturers. My typing is perfect today and the touchpad is activated too just to tempt fate. One thing I did do was to disable taps and turned down sensitivity of the cursor as well as it's speed too. These were ideas I read in forums that worked for some people. I just read today that there are ground issues with some laptops and two in ones like mine. Lack of a good ground between the keyboad and the display section. More fuel for thought and more possibilities for what seems to be an intermittant issue.
