    High CPU idle power with CPU idle

    I think the issue might be a windows issue, as this only started happening recently. I apologize if its in the wrong section:

    The issue:

    MSI GE75-9SG Laptop, Win10 PRO

    Until about a month ago I would get 4 - 5 hours of battery life, Now I get less than an hour.

    CPU is 0-1% usage at idle

    CPU power (while at idle) is 7 - 10 watts, previously it was a mere 0.2 - 1.0 watts at idle.

    This constant high idle power has tanked my battery life, and is uncomfortably warm when doing basic word or web browsing. This wasn't an issue before.


    What i've done:

    Tried uninstalling Windows updates from the last two months, via admin cmd, and via windows software utility (Two keep reinstalling upon boot, OS wont let me block it: KB4515871 and KB4532693)

    High power usage exists in Diag mode/safe mode without networking, running only windows services. (No background programs running, hence the low cpu utilization). All figures are based off the laptop being in power saver mode, so the cpu runs around at 800 MHz in this mode, rather than full speed, which is how I previously was getting decent battery life.

    Re-flashed BIOS.



    Any input, suggestions, questions or feedback are appreciated. Really frustrating to go from a pretty decent battery life to next to nothing.



    Thanks.

    use balanced power scheme ,slider as you need
    ,.cpu will use the range 800mh to max turbo freq ,slider sets the sensitivity ,.max power use base clock + max turbo ,other use full range

    That's not the problem. As mentioned in my posted, all numbers are in "Power Saver" mode, and the processor runs on minimum power (and does run at 800 mhz, as previously mentioned) determine from the chips specs and BIOS settings. Which essentially means that slider your talking about is all the way to the left. I am looking for a technical solution if you've any idea's. The chips frequency is at a minimum voltage and frequency, but the wattage that it is pulling at idle is many times higher than normal.

    I checked my throttle-stop, the C states looked normal. I deleted the INI file and nothing changed. It's the same with or without TS. Also the CPU is locked, I cannot modify the power states. (9880H).

    Maybe Dragon Center is set to the high power setting.

    In case anyone cares, or has a similar problems in the future: It was the intel iGPU. It was pulling maximum power regardless of load. The thing that fixed it was a clean driver install. I don't know how it happened however.
