Every few seconds I get a new event from UserModePowerService in Event Viewer. I think there are tens of thousands of them!

Hello there. 👋

Does anyone know why do I have sooo many events in my System event logs from UserModePowerService? Like, a new event from that source is generated every few seconds! I think there are, literally, tens of thousands of these events! See screenshot.

Is this a problem? Doesn't seem normal.

Thank you for any help!

I'm not a laptop person, but that sounds like a battery/power issue?


I found this...

I tested, this issue will go away if you set it to maximum performance when connected to AC power, you can keep your original power scheme under battery power. You will not see this event if you do as this.
This issue only happens if you set the computer in any lower performance schemes when connected to AC power.
As others mentioned in other forums, this is a kind of bug only existed in the new 12th generation intel CPU.


I don't know if this will help or not...

I found the same info as @Ghot. It's well documented for 12th gen core cpus. I did find where setting power plan to Windows default balanced plan fixed it for some. I recommend you make sure you are running the latest Asus bios as well the latest chipset drivers. Use Intel Driver & Support Assist tool to scan for the absolute latest drivers from Intel. The OEMs drag their feet in getting them on their site sometimes.

Are you experiencing any problems? I found out years ago that I could save myself a lot of unneeded headaches by only checking the System Events when I was actually having trouble with my computer.

I have this problem on my 8th generation Intel laptop (system 2 under my computers). Following @Ghot comment above, I reset the power plan to default (which has plugged in CPU power at 100% and also battery CPU power at 100% in the 'active' settings) and the user power settings have indeed disappeared. Unfortunately I have another power related problem which appears in event viewer as kernel power event id 105, which is that on this rather elderly laptop, the DC socket on the motherboard has become somewhat loose, which means that the power constantly cuts in and out. I fear a new laptop will be required soon.

    Dell says this system is not Windows 11 capable, but Microsoft seems happy with it.
Thank you everyone for your responses. I will look more deeply into them. A quick note from now: Now I noticed that these events appear when the laptop is on battery. I plugged in the laptop just now and see that when it is like this they don't appear. I will experiment with plugged-in in charging mode also, because right now it is fully charged.

There are some programs that switch Windows to its high-performance mode for the duration of some internal functions. (Wallander's NotePerformer sound library is an example.) I don't know of any way to tell this is happening (other than seeing the logged event records) unless the the developers or programmers document it. Having that happen every few seconds seems unlikely, but you never know.
