Touchpad Trackpad inoperable after sleep

Guys I see hundreds of posts on this old and aggravating topic with totally guesswork "answers" from Microsoft, help forums, including this one. There has to be an answer, right?

BTW this seems common on all types of laptops irrespective of make. I have tried this with both the vendor [lenovo] driver and with standard MS provided "mouse" driver. No diff in this regard though the packages are very different [lenovo very complex]
Also, this is a new phenomenon on this particular unit. In the past, no issues. Windows power-plan update?

as title says. Use laptop. Leave laptop [plugged in or not does not matter]. Return to use laptop after hours. Laptop awakes by normal means but no touchpad/trackpad etc function. Logoff, logon, still no touchpad cursor movement [frozen in centered position].

There is no Power Plan setting for "mouse" or touchpad or trackpad.
There is no Advanced Tab in Device Manager for same
There is no sleep/power/etc settings anywhere in Device Manager for same
There is no Windows error related to the problem
Full reboot required to gain coherency

Something in Power Mgmt, I guess, is offing the touchpad but the parameter is not obvious.

Someone somewhere knows this answer, right??

from chasing a lot of threads on the subject, I come to exactly the opposite conclusion.
its a stubborn issue for sure because it fools the 2nd line support people at the vendors and they call the hardware in, replace the touchpad, return to the joyous user, and within a month or so the problem resurfaces.

this has to do with drivers somehow. in my case, I've used the notebook for years with a small ssd and never once saw the issue. swapping out the drive to a bigger/faster one, I reinstalled 7 with all the current patches etc and now have the issue.
I see one or two other power-plan issues that I did not experience prior.

anyone know how DCOM calls play in returning/resuming from sleep? the only error worth noting is seeing a red error on a disallowed DCOM call which I assume is a windows permissions error [that is, MS biffed the code].

can someone answer this bonehead question [which I should know but don't]: what bus does the embedded trackpad sit on?

For what it is worth (perhaps you don't even have the laptop anymore), but still:
I experienced the same issue: not having the trackpad working after sleep (external mouse did work when connected, btw).

I found that closing and reopening the lid did reactivate the mouse function of the trackpad. I found out inadvertently after a long struggle with the phenomenon.

Hope this post helps those who experience the same problem.

Cheers!

Thank you so much for reporting this. On my Thinkpad T440 this worked.

You saved me so many future reboots (the only solution I had so far)!

Atrus.
