Acer R3-471T lost its Synaptics Touchpad after a recent Windows 10 update.

This question may look familiar but I've tried all advice from various forums yet my TouchPad remains dead. I tried "Fn/F7" "on/off", Several times I Removed/Reinstalled driver 19.0.7.34, (I had to use free revo uninstaller to completely uninstall the Synaptics driver). I re-installed Windows 10. Took LapTop apart, inspected H/W esp. flat cable connection to touchpad module. The symptoms are same no matter what: Dead touchpad, no pointer on screen, a USB mouse works fine. It has a touch screen & that works fine too.
Under "Device Manager": "Mice & other pointing devices" it shows "Synaptics PS/2 Port TouchPad" but with a yellow warning triangle appearing over the mouse symbol.
Under Windows settings/devices/mouse: it looks normal until I click "Related settings" "Additional mouse options" a Windows error box apears" : "Synoptics Pointing Device" "Unable to connect to the Synaptics Pointing Device Driver......................uninstall / reinstall driver etc." Thank you if you can recommend other suggestions, I don't have another TPad module to try but it was ok up until I did the Win10 update.

Hi,
Could you please check in BIOS whether the touchpad is in Basic mode or Advanced mode. Go to BIOS, move to Main tab and check.

Hi There,

Try the below mentioned steps.

• Uninstall the Synaptics drivers

• Do a power drain by removing all the external devices and disconnect the batter and adapter, after that HOLD the power button for 10secs

• Turn on the computer download the Synaptics software, right click on the setup file and run the software in previous version compatibility mode and install it

• Restart the PC and check the status.

My BIOS at the Main tab lists only seven line items and "Touchpad" is not one of them. I was going to try downloading a different BIOS, but was put off by Acer's warning about possible messing things up. Thanks.

Hi,
OK, I just wanted to make sure that you don't have Precision touchpad in your laptop, go to Acer support site and download the driver(19.0.7.34), extract it to Desktop, go to Device manager, right click the touchpad and click update the driver, then select "Browse my computer....." and select the Desktop. When you said there's a yellow triangle sign against Touchpad, that means the driver is not properly installed.

brummyfan2, I did what you suggested. Feedback from device mgr was: "The best drivers for your device are already installed" then I was offered to click "microsoft Windows 10 updates that might help the drivers" (or similar wording) That action too said "my device was up to date". Everything about the driver seems fine except the "yellow triangle sign against Touchpad" is still there.

Hi,
Try running sfc /scannow command at least 3 times.

Thank you for your help. sfc /scannow ran 3x and "did not find any integrity violations". I'm beginning to believe I have bad hardware.
