Hello Emmanweng and welcome to community forums!

Any changes made before the issue came up? Are you using a custom OS or company image OS? Could you provide the OS version, BIOS version and the machine type model or MTM(ex: 10VG0005CA)?

This would help us get the model variant details while keeping the confidentiality of the serial number.

Try running a hardware scan from the Lenovo Vantage app to check for possible hardware failure.

Try running the System File Checker to fix corrupted system files.  Type sfc /scannow on the command prompt and hit enter . Make sure you are running as admin.

If the issue is still the same, try installing the OEM image to isolate the issue through this link: https://support.lenovo.com/us/en/solutions/ht103653-lenovo-digital-download-recovery-service-ddrs-download-the-files-needed-to-create-a-lenovo-usb-recovery-key

Let us know how it goes.

Good afternoon 

We have the same problem. all updates through Lenovo Vantage are done. We used OEM image. Cpu, Disk and Memory are closed to 100%. We have cases where there is a drop in performance during the day and in other cases after taking the computer out of lock after lunch. 

they freze and he have to turn off in the power button manually.

All these reports started about 2 weeks ago.

we are tested now the sfc /scannow.

I Attach some DUMP´s from the laptops affected.

Hello!!

We have the same problem in 10 machines. The RAM maxed on and finally it crash.

Our last test: we unistall the Lenovo Vantage and lenovo.modern.IMControler, we are waiting results.

I am Emmanweng the one who originally post this for some reason my first lenovo is having issue... anyway I did the above tips by Jwez but it didnt fix the issue. I also did the following troubleshooting steps but it didnt help me fix the issue.

1. Rollback drivers

2. Update drivers thru WSUS (online) and Lenovo 

3. Run sfc and DISM

4. Set standby mode to S3 (default S0) applied this based on the dmp result PDC_Watchdog_timeout that i have posted  

5. Adjust GPU settings apps like teams, chrome and  etc.. 

The weird part of this issue is even the user device is idle the device resources usage are still slowly increasing. 

For us run the comand sfc /scannow didn't solve the problem.

Hello

Someone have the solution? we continue with the same problems doing the sfc /scannow, too.

Hi All

I'm investigating the issue with my internal team, I hope get some Lenovo moderm imcotroller log from you. 

If Lenovo moderm imctroller used top-1 memory size on your system, please download the log tool from below link, double click to run the tool and then find logs in C:\programdata\lenovo\Modern\Logs.  (Please unhide programdata folder if you cannot find it under C drive).
