XPS

[Topik]

I am having this weird issue on my Dell XPS 15 9570 where the touchscreen doesn't work after I close the lid. If I reboot, the touchscreen works just fine, but as soon as I close it, it ceases to work. This happened after I updated to the latest BIOS, but I'm unsure whether this is the issue or not. I already reinstalled Windows, so that's not the problem. This is a very annoying issue, especially considering that I bought the more expensive model for the touchscreen. Any help is appreciated! If you know of a solution, please reply to this post or DM me on Discord at Topik#0001

Thanks!

Same problem on UHD 9570 with the latest BIOS. Restart required to turn touch back on.

Hi Topik,

Thanks for posting. Apologies that your system is not performing as expected.

Unfortunately your post does not indicate whether or not you've updated your BIOS or run SupportAssist.

Please run the Dell SupportAssist , make a note of any error messages encountered and post back.  Also, in the BIOS there is a setting called USB Wake Support.  Some users have reported success by turning this to the off position.

Here is information from the Dell Knowledge Base you may find helpful:

I'm not Topik, but I ran SupportAssist, no problems were found and all drivers are up to date. I entered the BIOS and disabled USB Wake Support. The problem still persists. Upon closing the lid and reopening it the touchscreen does not function. Regrading the links provided, this thread is about touchSCREEN failure, not touchPAD. This is a pretty expensive upgrade and having it fail to work anytime the lid is closed and reopened is frustrating to say the least.

Hey Robert,

I'm pretty sure that the other users are referring to their touch displays and not their mouse touchpads...

I don't think your knowledge base links are relevant here.

Hey Topik,

Did you ever fix your touch display not working? What BIOS version are you on?

I see this in the release notes of the latest version of the BIOS that I have to download. See point 2:
