Lenovo System Update Service (32 bit)

2021-02-06, 18:00 PM

It seems a process called "Lenovo System Update Service (32 bit)" is using 15 to 20% of my CPU continuously, and is causing my P52 to breath heavily (fans going constantly and loudly).  Now, I know how to disable the service, but this only stops it during my current usage.  when I reboot the service comes back on.  

 

Does anyone have any notion of what might be causing this?  I went and used Lenovo Vantage to make sure my machine is all up to date.  One of the updates it gave me was a BIOS update.  This did not change the behavior.  Right now I'm all up to date, so I don't know what this service is doing burning up so much CPU time.  

 

I also don't see a way to report this problem to Lenovo directly, so that is why I'm mentioning it here.  If it continues to be a problem then I will just start removing things like Lenovo vantage and anything else that might be the parent of this process from my computer until the problem stops so my computer will rest when not being used.

But I am wandering why you are releasing a new version through a forum?

 

I can't tell if these are serious questions or not.  First thing you could check is that URL is coming from https://download.lenovo.com, next thing you could check is Lenovo signature on the file.  Anyway, this new version has since been linked on the support website here:  https://support.lenovo.com/us/en/downloads/ds012808-lenovo-system-update-for-windows-10-7-32-bit-64-bit-desktop-notebook-workstation

Hi IndianaBK,

 

Welcome to the Community Forums.

 

It would be expected that it runs continuously since it part of computing maintenance service.

 

System Update downloads software, driver and BIOS updates from a Lenovo server directly over the Internet without requiring specific user knowledge of where the package is located or if it is needed by the target system.


The benefit to help you keep your system up to date and secure are: -

Provides a direct connection to Lenovo server and support for ThinkPad and ThinkCentre drivers, software and BIOS updates. -

Helps maximize your system performance and minimize security vulnerability.

 

If you feel that you are just ok without them, then you can decide to disable it along with other Lenovo offered apps services.

 

Doing a clean boot also helps you lessen system workloads.

 

I hope this helps answer your query.

 

Regards,

spidey101

"It would be expected that it runs continuously since it part of computing maintenance service."

 

No, that's incorrect. To use a car analogy, that's like saying it's normal that your engine is always revving to the red line (even when idle/stopped) because the engine control unit is maintaining the proper function of the engine.

 

The original poster does not realize that "15-20%" of his CPU really means that one entire CPU core is being "eaten" by this System Update service. I am experiencing the same issue, as are dozens of other posters on Reddit and here in this forum. The reason it comes up as 15% is because that's approximately the inverse of the number of logical threads on the CPU. Example: 2 cores or 4 threads (with Hyperthreading) = 1/4 = 25%. 4 cores or 8 threads with HT = 1/8 = 12.5%. The original poster might have a 6-core CPU with HyperThreading disabled to get to 15-20%, since 1/6 is 16.67%. Or the System Update service is using slightly more than one CPU core.

 

In any case, this is TOTALLY unacceptable. SUService.exe is supposed to run in the background, but the expectation of system services like this is that they should be idle nearly all of the time. A well-behaved background service will take up 0 to 1% of the CPU almost always, and only occupy a CPU core as intensively as this one is in case it's actually doing useful work (like updating your system). Those of us who are reporting this bug have confirmed that SUService.exe is not doing any meaningful work such as updating the system when this problem occurs.

 

If every system service occupied 15-20% of the CPU, the system would be completely unusable. There is no good reason you can give me that SUService.exe should fully utilize an entire CPU core 24/7. The difference in power consumption is like 90 watts vs. 15 watts normally on a 10th gen Core i9. You guys are literally wasting peoples' electricity.

 

This is a genuine bug and it needs to be fixed ASAP. If you continue to deny this, I will have no choice but to promote awareness of this until it reaches the front page of Reddit and Slashdot and embarrasses Lenovo in the tech press.

Indeed, I am not confused about what the process is supposed to be doing.  Nor am I concerned that it appears in the list of active tasks.  I expect it to be there.  The problem is that it is tying up so much CPU the capacity.  Enough that the cooling fans can be heard continuously until I stop the service.  The CAD software that I use the computer for doesn't even tax it so while using it.

Just adding one more voice to report this problem in the hope that it'll be looked at. That service is consuming around 20% of my laptop's resources 24/7. Please fix it, or let us know where else we can report it.

 

There is a Reddit thread with many people reporting the same problem: https://www.reddit.com/r/Lenovo/comments/lc23dz/lenovo_system_update_driving_high_cpu_usage/

Questions...

Are you all running the Lenovo Vantage application? Or are you all just running the separate System Update application?

Looks like both System Update and Lenovo Vantage are on my computer as available apps to run.

 

Running as services I find one called "System Update", described as "Lenovo system update" (this is the offensive one that is using around 6% of my CPU right now), and another called "Lenovo Vantage Service".  I think I'll try just removing the System Update app and see if that gets rid of the aggressive background service.

That did it.  The resource hogging update service is gone.  Lenovo Vantage Service is still there, but it is taking up 0% of the CPU like a good background service should.  I'll accept this as my solution to the problem.

I also end-tasked that program (Lenovo System Update Service) through task manager, and the CPU-hogging behaviour has not returned after a restart. 

 

Before killing it, the behaviour would persist across restarts, so it seems like the problem is also fixed for me.

Thanks for replying back with your results.

Happy this is moving in a positive direction.
