    A. Two video cards: in one of the threads I posted you will have read about a spurious 2nd Intel video card driver being installed and removing that solved the problem.

    Question: do you have two cards in your PC? When I looked at the spec I saw no reference to the Intel card but could have missed it. If those drivers match what you expect, it's fine.

    B. Task Manager - whatever is 'Microsoft Drivers'? Ok, not huge CPU use, but that deserves research. Your idle CPU use would ideally be under 3%, preferably lower (Depends what background software you have installed - some added services etc use more CPU time than I'd like to see).

    DWManager CPU use shouldn't be that high.

    C. BIOS- I seem to recall the latest date was 2013. But if your version is latest, that's fine.

    D. Fan control - see refs to ACPI under system devices in your Device Manager (I have about 10 references, not all of which can be relevant). The fan control is managed by sensors on your motherboard and ACPI drivers.

    The Drivermax offerings don't immediately stand out to me as helping there. Maybe the Intel ones- I can't tell. But you don't really lose much by trying them. (Drivermax allows 2 free a day)

    yeah for n46vz i got two cards, its intel HD 4000, and nvidia gt 650m. i think from that thread, the problem is that guy got 2 driver installed for nvidia or intel ? as for me i got it normal, 1 driver for each of intel and nvidia. because u see that in my case, there's driver for nvidia that failed to update on 'windows update' , and then i installed nvidia driver for win10, the same for intel driver, i updated it to latest version.

    idk about microsoff drivers, in process its named "spcdh.exe" and i cant find anything in google.

    about bios, im sure that latest ver. 409 bios for n46vz is from 2012.

    is this the ACPI ?


    after researching about unknown device, i read that i should get that driver 'Hardware ids'.
    and its root\DTSoftBus01 and root\amppal​.

    Task manager: if 'Microsoft Drivers' is still running, try rt clicking it, Properties, and post a screenshot. Thanks.

    As to the last para, sorry, no idea.

    At some point you will need to decide whether you agree with your manufacturer that your laptop is not compatible.. I'd check their forums, post a question there.

    Hi, fwiw I don't have spcdh.exe anywhere .. is it always using that much CPU time?

    You seem to be missing two ACPI-related items near the top of the list.
    Just wondering what you have for this (power button) given the ones missing:

    You could try updating all the ACPI drivers individually, but doubt that will achieve anything, unfortunately.

    Have a look at a fresh scan of DriverMax, and if not already done as above, try updating some drivers.. you shouldn't lose anything. Windows will cause them to revert to its version within a day without special action.
