Touch Screen not working - need troubleshooting steps
Touchscreen quit after installing my fitbit. Now my only exercise I get is with my fingers. I rebooted and looked for pen & touch but it is not there. No "Touch" human interface device. No tablet settings. I have not been able to find a hardware check for the touch screen. It there such a thing? I have only seen that I need to "refresh my PC". I have been there before - no fun at all and you don't know what you lost for months. I just want to see if the hardware is working.

Hi,
I would suggest you to update the BIOS on the computer. Please enter your service tag # on the link below, then download the BIOS required onto the system and install it.

After the BIOS update please check if you find any device under Human interface in the device manager. If not please consider reinstalling the operating system.

I am not looking for a way to fix it. I have lots of advice on how to fix it. I am looking for a way to test the hardware.
What I found is that it will fix itself if turn the computer off and close the lid for 30 min or so. When I turn it back on it is working fine. I tried a simple power off and on but that did not work. Sounds like hardware right? So how do I test the hardware?

What happens if you disconnect the USB dongle for the fitbit and uninstall the driver for it?

The touchscreen failure has not recurred. Our fix (power down, close laptop wait a day then try again) has worked twice.
I am still very disappointed that the industry seems to have no way of testing touchscreens. Fixing things by playing with software mods wastes lots of time because there are endless possibilities. Eliminating hardware failures should be the first step not the last resort. Laptops are very susceptible to hardware failures due to their delicate nature and the fierce manner of their handling.
