High CPU Use and battery drain by CxUIUSvc Service on L13 20R3000EIX

2021-03-07, 8:59 AM

Hi,

 

yesterday I have updated my Lenovo L13 with Windows 10 Pro x64 20H2 and other updates of Lenovo Vantage App.

 

After that updates I have now the CxUIUSvc Service that drain 25-40% of CPU load constantly.

 

I have read that depend from Synaptics driver and I must update the Synaptics Audio Features driver, but on the support site of Lenovo I have finded two versions: vpro and n-vpro. Which one should I use?

 

How can I resolve?

 

Thank You

Hello casIT,

 


Welcome to Lenovo Community

 

Based on the readme file, you need to use the n-vpro for L3 20R3 models

Also make sure that the BIOS is up to date thru the support site

I have the same problem, upgrading to the last version of the drivers and BIOS did not help.

The CxUIUSvc Service uses about 40% of CPU, causes high cooling fan speed and annoying noice.

Re:High CPU Use and battery drain by CxUIUSvc Service on L13 20R3000EIX

I'm having the same high power drain / high fans speed / 30%+ CPU usage with the CxUIUSvc Service

 

I have a 20QTCTO1WW (Thinkpad P1 Gen 2)

I ran the Lenovo Vantage update yesterday, and it did a Thinkpad BIOS Update to version 1.38

 

I have no applications running, but the CxUIUSvc Service is consuming 27% CPU at the moment with the fan blasting at full power.

 

Any recommendations would be greatly appreciated!

 

Thanks,

Nick

Hi, after the updates (Windows & various Lenovo from Vantage app) I have also some problems with Microsoft Excel that suddenly it closes causing me to lose my data.

 

Does it happen to you too?

 

Do you think it is a problem that could be caused by Lenovo or Microsoft software??

 

Regards

Hi.

Help required.

I have a similar problem.  The CxUIUSvc Service is using about c.67% of CPU, causing almost continuous high cooling fan speed with accompanying annoying noise.

Rob.
