    I just turned all the power saving off, no sleep mode , never turn monitor off etc etc but this sounds better. Thanks

    This fix works on multiple platforms, and on other branded products too. :whistle:

    Hi Ken,

    I tried the fix, but I still have problems waking up the Z83-4.

    It seems to depend on the time between the Z83-4 was left unattended. If it is a short period it works OK. For a longer period it doesn't want to wake up. I tried the trick disconnecting the HDMI cable. That doesn't work.

    Does the Z83-4 have different levels of sleep? I noticed that first the screen goes black. Then after some time the numlock and function light on my keyboard are turned off, but it can still wake up by a key press. After a longer time there is no means to wake it up; not by the keyboard, not by the button on the Z83-4 and not by disconnecting or reconnecting the HDMI cable. The power led is on and green and also the leds on the Ethernet port are on.

    Best regards,
    Jan

    Is your BIOS updated to V1.4?
    This fix has been verified by Intel and there is no better fix until they release a new driver for these platforms.
    Personally I don't experience the issue you mentioned, with everything most updated (Windows, graphics drivers, BIOS, etc...), nor I can see other reports of the same kind on this board.

    Yes, I did update my BIOS to V1.4. That doesn't seem to make a difference.
    The Intel Graphics HD driver was version 20.19.15.4380. I'm updating the driver now.

    Hi Ken,

    If I install the Virtual Display Enable Disable patch will it prevent me from running Windows Remote Desktop on the MINIX PC? I bought the MINIX PC to use as a local PC running a robotic mount with a couple of telescopes on it capturing image data. I access the MINIX PC system over the network using Wi-Fi from a remote location. Thanks!

    BTW: firmware has been updated to 1.4

    I still the same problem after the updates. Only disabling sleep mode prevents it from freezing.

    Yes! If you need remote (virtual) desktop you can't use this patch!

    What is your current graphics driver?
