Inspiron 15 7000 series 7559 - No touchscreen after Windows 10 update

" Dell support has only been able to tell me to send it in for repairs. That is not really an option for me, and it is a bit ridiculous given that it seems to be software "

:emotion-2:

You sent off the laptop to Dell ? Or you fix the touch screen problem ? Any updates ?

I do suspect a corrupt windows update or you took out a USB flash drive without ejecting it from the taskbar.

By the way, thanks for the images. 

It has not been fixed yet. I didn't send it to Dell, hopefully it will not come to that...

Do you have any suggestions on how to proceed? It seems like the driver is screwed up in some way, but I can't find any driver for it online- I assume it is supposed to be embedded in Windows.

Thanks!

' Currently, this hardware device is not connected to the computer. (Code 45)"

I usually see this error code 45 when I unplug either external drive, USB flash drive, printer or head phones without ejecting from the taskbar. I suggest you check for any unknown devices in Taskbar. For example; If you see USB flash drive icon, even though there isn't a flash drive in any of the USB ports, you should plug a USB flash drive into port and then eject from the taskbar.  

Fourth.....

Go to device manager,expand Human interface devices, right click on first USB input devices, Properties, and then Power Management. Unclick all boxes.

Secondly, I suggest you power off system and then disconnect all peripherals. Power on system again, hopefully touch screen is working now. If the touch screen still isn't working then I suggest you run windows update troubleshooting tool on system. Please type Troubleshooting Control Panel onto {Cortana} search box, click 'view all' and then windows update. I suggest you run the other tools as well, see image below.

Touch screen may have intermittent issues or stop working due to power management settings

Third......

Go to device manager, update Disk drivers, Display adapters, firmware (see image below), and then power off system. Power on again, hopefully touch screen working now.

Tried those with no success. I restored Windows from the Windows 10 disk that I downloaded off of Dell Support. Now, no touchscreen appears in Device Manager. It is not just hidden and disconnected, there is simply no touchscreen. I am relatively sure that this is a driver/update issue, but Dell provides no touchscreen driver! It simply is not available. I am going to try and badger Dell Support later, but frankly, they are apparently not competent- if they were, this issue would be resolved.

The touch screen driver should be in one of the windows updates. Please check for the latest windows updates are installed on computer. Press Windows icon key + R key, type ms-settings:, and then select OK.  In Settings, choose Update & security, Windows Update, and then select check for updates. Install any available updates and restart your PC if required. I also suggest you check 'Update History' for any fail updates.

Update System Setup(BIOS) and see if that make a difference. Please click on link below:

After you updated BIOS then I suggest you update Chipset and video drivers in correct order. Please click on link below:
