T14 Model 20S0002FUS - BIOS Update issues - N2XET27W (1.17)

T14 Model 20S0002FUS - BIOS Update issues - N2XET27W (1.17)

2021-03-09, 16:16 PM

I've noticed an issue with the updated BIOS 1.17.  The CPU fan is running non-stop. System randomly shows high CPU utilization sometimes 95% or 100%. Lasts 30min on avg.

 

I have several T14 laptops on BIOS version 1.14. The CPU fan rarely comes on. Maybe once or twice per day. The system never hangs or shows high CPU utilization. I've built 6 units identical with software and configurations. 

 

3 on the older BIOS run without the high CPU utilization and no system hangs

 

3 on the newer BIOS which all have high CPU utilization and system hangs.

 

 I also have one system that was on BIOS version 1.14 that upgraded today 3-9-21. Once the system rebooted and the BIOS update was completed the CPU fan runs non-stop. And high CPU utilization.

 

When will the next BIOS version be released? Hopefully 1.1X or whatever that may be fixes the issues??

Almost the same issue here with the same BIOS version, except for the high CPU load: https://forums.lenovo.com/topic/findpost/1300/5068233/5269279

 

What I'm doing right now is sitting on Best battery life mode in Windows (move the slider all way left here https://prntscr.com/107q93j) and waiting for Lenovo to fix this stuff asap.

Unfortunately. Maybe the number of such same posts will be increased so Lenovo to provide the fix...

 

P.S. From other posts, high CPU usage can be caused by the Lenovo System Update service. You can check and kill it if this is the case.
