  1. Limited functionality of keyboard


    Greetings. I have a TOSHIBA laptop C859-B559. Prior to an upgrade from Win 7 to Win 10 the keyboard worked well. Sad to say That presently the numeric stays on, only the 1234679 keys are working, some of the function keys are working and the majority of the alpha keys are not working. This leads me to be using an ext USB or the OSK which is cumbersome. I first realised the keyboard condition while entering my PIN, having "Incorrect PIN" error each time I resubmit the correct info. Upon checking, I saw that in striking one key e.g 3, four other characters will popup along with 3. Since then I have been attempting all so-called corrective measures on the internet but to no avail. I replaced the keyboard with a new one from the store but my woes continue. Uninstalling device, drivers via Device Manager is a waste of rime since "best" driver STANDARD P/S KEYBOARD is already installed; drivers version 10.0.18362.1 in year 2006 i8042prt.sys & kbdclass.sys and 19.4.3.38 for SynTP.sys. Looking forward for a true solution to this vexing problem. Shalom.

    :)

  2. Intermittent keyboard non-functioning


    I use a wireless mouse and keyboard. Every now and then, often enough to be irritating, the keyboard fails to function: the mouse works properly. The keyboard problem persists for a few minutes, after which it works again. There is no discernable pattern to this problem.

    This is the third wireless keyboard to show the same problem, suggesting something is wrong elsewhere.

    The keyboard batteries are not responsible for the failure.

    On the same desk is a cordless telephone.

    Any helpful suggestions would be very gratefully received.

    Overclocking / Undervolting guide for Vega 56 or 64?

    Here's a quick laundry list:

    List of software to use for overclocking and testing
    Examples:
    Wattman (and how to find and use it, like an overview, including profiles)
    Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
    How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

    Step-by step overclocking in Wattman
    Fan speeds
    Power limit
    Temp limit
    Voltages
    Core speeds
    Memory speeds
