    GTX 980 = GTX 1060. It gets about 13K in Fire Strike Graphics.

    My issue has come back out of the blue!
    Resetting power plan won't do anything. Reinstalled all gfx drivers, still nothing. Incredibly frustrating

    Try disabling HDR, might be some bug that makes Optimus turn the dGPU on.

    HDR is disabled. When the dGPU comes on, my idle power draw DROPS (see third post)

    I saw that, seems like the dGPU gets stuck in some random power state, and using it and then closing the program that used it fixes the stupid power state.
    If that work around still works, well, its at least a work around.
    See if you dont have any program that is pooling the dGPU for stats, things like Afterburner, GPU-Z, HWInfo and many others will constantly wake up a dGPU and increase power usage.

    So to fix this when it happened, I did a full nuke and pave. The problem was gone and had 0 issues. Until today. The same problem has presented itself once more. Anyone else has experienced something like this? See first post in this thread for details.

    Try rolling back Nvidia graphics driver?

    When this happens to me I keep doing this:
    Enable Optimus
    Uninstall Intel Graphics driver
    Uninstall Nvidia driver
    Install both
    Make sure HDR is disabled in Windows

    See if it works. Normally doesn't so I then disable Optimus and the problem goes away.

    When you install the drivers, are you using the ones from Lenovo website or the latest relevant Intel/Nvidia drivers?

    Spent another 2 days troubleshooting, got nowhere... I would do another nuke and pave but I don't want to have to do this every 8 months or so...
