    Synaptics touchpad sleep problem.


    A bug I seem to be having with 2004 is after sleep I cannot use the touchpad to wake the laptop. I have a mouse connected but even if I disconnect this it still doesn’t work.
    I’ve rolled back the driver to the previous (working) one, clean installed the driver & disconnected the Logitech mouse.
    The problem seems to be that under power management for the device the ‘allow this device to wake the computer’ is greyed out.
    I as yet haven’t restored the original drivers but may try this after my daily Macrium backup.

    I can wake the laptop using the power button so I don’t know whether this is a new feature, a bug which is only affecting a small number of users or a problem.
    I have a mouse connected so am fine but it is a puzzle.

    Hi, you can review what's configured to wake your PC with the powercfg command of course.

    It does seem there's a slow trickle of device/driver-level oddities appearing in connection with 2004, 1 in particular with a number of people experiencing it.

    Ok, and does powercfg confirm your touchpad, in your current configuration, should be able to wake your PC? That's a long list, easier for you to check.

    Tbh I don't see Synaptics in the list.

    I've tried another clean install but I am worried about this as I cannot tell whether it has installed correctly or not:

    If not then I'll recover from my image.

    I've heard there's a problem with touchpads not working after startup but not after sleep with 2004.

    Another way to check if it's configured to do so is to rt click the device in Device Manager, Properties, and see if there's a Power Management tab. If not.. no option to wake the PC..

    As I commented, there seem to be a few device-related issues being mentioned- not related to the 'Known and resolved issues' list for 2004.

    FWIW my touch pad won't wake this one - 1903. Presumably yours did in an earlier build.

    Under the entry in Human interface devices there is a power management tab but the wake option is greyed out, under Mice there’s no power tab.
    Yes it worked fine under previous versions.
    I’ll put this one down to a bug I think.

    Odd.. I have no Power management tab on my touchpad on either laptop- but they have always only had limited options to use for waking.

    Presumably in 1909 or whatever your previous build was it worked, but not after upgrading to 2004.. worth adding a note in comments under
    Known and Resolved issues for Windows 10 May 2020 Update version 2004

    Thanks @dalchina, that was my first port of call so I’ve already posted there.
    Yes 1909 was working fine. :)
