UNSOLVED
Touch screen does not work
Dell XPS 13 9315
Always had a touch screen but suddenly it is not recognised
In Tablet and PC Settings (not originally listed) "No Pen or Touch Input is available for this Display"
Not listed at all under Human Interface devices.
All Windows 11 updates are installed.
Dell troubleshooting does not identify the problem at all.
The key board and touch pad work properly.
The bottom line is that the Dell system does not recognise that there is a touch screen.
It is very inconvenient.
How do I get the Dell XPS to recognise the touch screen?
Check the connection between the display and mainboard. Service manual:

@ejn63 Thank you but a little more precise information would help. I have tried everything listed on the troubleshooter without success except reinstalling factory defaults. I am travelling overseas and that is not an option until I get home. Please, where can I access the connection?
@ejn63 I do not understand how that can solve the problem. The display screen can easily be disconnected from the keyboard/touchpad/palm rest unit. Then I have a tablet(screen) without a keyboard. Without the keyboard attached I have a useless doorstop because the touch screen does not work. I need some advice on why my Dell tablet touch screen is not recognised.

First, there are two 9315 models -- yours must be the 2-in-1, not the standard 9315. Your question refers to the 9315, not the 2-in-1.
Check the pins and contacts on both the tablet and the case for damage, corrosion or anything that insulates one from the other. Clean the pins and contacts.
If that doesn't solve the problem, one or the other -- the case probably being the first to try -- needs to be replaced, as there is no way to service either component if it isn't making good contact.
@ejn63 Thank you. Yes it is a 2-in-1. That solution is not certain . The touch screen should work without the case, It is tablet after all. I will consider this further but it may be better to replace the machine with a Microsoft Surface - my previous one was afar better machine,
Finally solved this. A Dell technician spent a long time but it is actually very simple.
In my case under Device manager - Human Interface Devices both the touch screen and pen were not listed.
Go to Bios Setup - Press start and tap continually on F2 until the Bios set-up appears
On left side tap on Display
See a switch that says Touch Screen On/Off
Mine had been switched to Off by some unknown force
After changing it to On and rebooting - all good
Ran Dell updates and everything back to normal.
