I use Win 10 pro and do not have any yellow exclamation marks on any item in my device manager. Under "Human Interface devices" I have:
- HID-compatible Touchpad
- HID-conform device
- Microsoft Input Configutration Device
- Synaptics HID-Compliant Touchpad Device (Driver: Synaptics 220.127.116.11 from 27/06/2018)
Under "Mice and other pointing devices" I have:
- HID-compatible mouse
- Synaptics pointing device (driver as above)
It seems that a driver is not always loaded properly and a sleep seems to force a reload. However, sometimes it also happens after a sleep, and it does not happen after every hybernate, so it's really a bit unpredictable. It's just annoying when it happens.

Hi guys, I had the same problem. Now I think there is a fix available.
Go to device manager, open mouses and other pointing devices and double click "Synaptics Pointing device". Open "Drivers" tab and click "Update driver". Then click "Automatically find a driver" to let Windows find a new driver online. In my case, the original version of the driver was "18.104.22.168" and was updated to "22.214.171.124" with a date 2018-08-19.
(I have Windows in Czech language, so options from upper paragraph may be slightly different, I had to translate it to English.)
I'm on this updated version for two days with several hibernation / wake-up cycles and it seems to be much better.
The irresponsibility is caused by the fact, that when it is "broken", then touchapd starts accepting gestures after maybe half seconds after your fingers actually touch surface. This is why you have to move much further to go through screen, first half of the second does not have any effect on cursor. Also this is why touch doesn't trigger mouse click. After update of driver there is still some feeling that touchapd starts responding later after initial touch, but a) the response delay is much shorter (100ms maybe?) and b) it seems to disappear at all after few minuts after resume and then touchpad starts to react immediately after touch.
I guess it may have something to do with power management, maybe touchpad simply doesn't wake up, or maybe it is waking up every time you touch it and it takes half second to initialize. Hell knows. User is unable to define power management options for devices in Windows 10, so we can't test it.
For Lenovo: It is a software / driver problem for sure and you have to do something with it.

I just tried Your solution - it wont help in my case :<
Still similar effect.
But I have 100% working solution.
I called Lenovo service ( I have on site guarantee) and they remove old touchpad and istall new one. It took 30 min and after 15 restarts and hibernations everything still works perfect!
EDIT after several hours:
I rebooted system and... touchpad issue come back again :<<<<<
Lenovo - do something!!!!

After last Touchpad firmware update and BIOS firmware update I dont have any issues with Touchpad. It works now for over 4 days. You can find all updates on Lenovo Vantage/System update.

Yes, after 5 days, issue returned. Obviously Lenovo doesn't care too much, its a pitty because othewise I am very satisfied with their products. I think this is not a HW issue, so it doesnt make sense to send it for repair.
