I have an Ideapad S500 Series Touch (ideapad S510p Touch), that was originally a Win 8.1 unit, upgraded to Win 10, then somehow was restored by hitting the one button restore button near the A/C Adapter plug-in. It was factory restored accidentally, and then upgraded again to Win 10. The touch screen will not work with any driver (I have tried every eGalaxa driver out there and the patch), but, it wouldn't work at all since the accidental restoration no matter the OS installed.
I am looking and failing to find anywhere so far the required proper Firmware Upgrade file like the S400 series one at this Lenovo link.
Inv.gy/1PuBoFq (This Lenovo URL Shortened w/Bitly.com)
It would be the eGalaxaUpdateAuto file for the S500 Series Touch ideapads I am looking for. And it contains the Firmware Flash file & the eGalaxaSensorTester.exe file for the S500 Series.
Does anyone know where it is located please? I have all the flashing, testing, & calibration instructions and am a repair tech. The computer of course is out of warranty. Why didn't the engineers that designed that wonderful one click restore button think of hiding it inside a rear compartment like near the memory chips? Much too close to the AC adapter plugin at less than a quarter of an inch...And the lpug has sharp corners too boot! Once more, one click restore icons on the desktop as default also? What's up with that.....
If I receive the file soon, I will work up an easy solution to a problem that many people have and publish the simple solution to the Lenovo Touch Screen Issue that plagues many. It can not help their Touch LCD unit sales whatsoever as thousands of ticked of customers (most having out of warranty units), never helps any company.
Thank you in advance.

Try this and see if it works for you.
.1. Press Windows + X.
2. Select Device Manager.
3. Find the Touch screen driver under Mice and Other Pointing Devices > i.e. USB Touchscreen Controller(A111). You're going to uninstall this and check the box that says "Delete the driver software for this device".
4. Restart your computer.
5. Re-open the Device Manager, and confirm that the Touchscreen is now listed under Human Interface Devices.
If not, look for any Universal Serial Bus Controllers (including hidden devices (View > Show Hidden Devices) and enable them and/or update their drivers.

I followed what you said and fully appreciate your time in posting the info. And the touch screen shows up under HID Devices. It still does not work. According to what I read elsewhere concerning the S400 Series, Flashing the eGalaxa LCD Firmware actually does the trick. But the Firmware & eGalaxaUpdate testing and configuration file I cannot seem to find anywhere (the S400 file does not work for the S500 Series Touch devices as it says so, and it also says you need the proper file...Even places where I read it was previously listed I cannot find it among their downloads. Lenovo must have the file.

Have you checked here: http://www.eeti.com/drivers_Win.html
The have a Windows 10 driver, but I do not see any firmware. But you might contact them directly at their US office and see if they can help.
