Surface Pro 2017 touchpad mouse freezing

actually the "Power" tab under "System" is missing altogether). Another dead end...

I had the same issue - the Microsoft driver that was installed by Windows update for the graphics card is... less than current.

Went to Intel, downloaded the drivers directly, and Microsoft had, of course, blocked them from being installed - had to download the .zip, go to device manager, update manually, then I got the power options - however, for me anyway, the Panel Self Refresh option only shows up in the 'On Battery' section - I switched it anyway, and gave a reboot - I still ran into the issue, but this at least gets me closer.

Hello

I can't figure out how to unsubscribe from this thread. 

Please don't send me a automatic reply.

I've tried all of those. 

Your help page has a hotlink that says: "on the question" unsubscribe. 

When I go there, there is no unsubscribe link anywhere on the page.

Thx

Many prior posts implicate a drained battery, particularly among the older Surface Pros.  I have a Surface 5, i7 7660U/Iris 640.  So the current fix appropriate for the Surface 7 won't/doesn't work for me.  I've purchased a new battery and am waiting for the appropriate moment to install it.  Will let you know whether that cures my problem.

Incidentally, the only thing which appears to resolve the issue immediately for me is detaching/reattaching the type cover, which has the effect of resetting the USB bus over which the type cover communicates.  In the older models, there is likely a problem with the USB bus driver which causes the graphics card to believe (wrongly) that the user is attempting to switch from using the trackpad to the touch screen.  I note that, while the trackpad is not working, the touch screen/pen work fine.  Getting back to using the trackpad, however, mostly requires the detach/reattach trick.  But often, before this becomes "mandatory", I can relieve the issue momentarily (depending on the active application), by hitting the ESC and right-click keys, or the ESC and DEL keys, in rapid succession.  Why?  It's a mystery.  Probably all a USB bus driver issue between the type cover and the system, at least in the older models.

Hi @Matt Snead,

Thanks for your reply. I installed the Intel Graphics Command Center from the Microsoft Store and the option you mentioned in your post doesn't even show up (actually the "Power" tab under "System" is missing altogether). Another dead end...

I thought perhaps this option only appears in more recent models, but then I searched through Intel's support and it lists my iGPU (Iris Plus 640) as supposedly supporting this option. This Intel support page (https://www.intel.com/content/www/us/en/support/articles/000057194/graphics.html) has a note saying "Panel self refresh is available only for embedded DisplayPort 1.3 (eDP 1.3)." The fact is that I don't see the Panel Self Refresh option or even the Power tab. Any suggestions?

This is just a ridiculous lack of response from Microsoft...

Did you try the fix I posed in the post above yours?  It has worked for many.
