ThinkPad T-series locking processor speed to 0.39 GHz

2021-04-01, 21:58 PM

I've had a handful of T480/T490/T14 computers in the past few months with reported slow speeds. Upon investigating, it looks like the processor is throttling itself down.

 

I haven't had this issue personally and considering how few users are reporting it I think that maybe there is a potential hardware or firmware issue going on. Has anyone had experience with this? The last user I worked with, I ran all system updates, then uninstalled all Firmware items in Device Manager and that temporarily fixed the problem but it has now come back. No other updates are available.

 

Let me know if there is any log collecting I can do that would be helpful in diagnosing the problem.

 

Thanks

Hello ngreene!

 

Welcome to community forums

 

Any changes made or any updates installed before the issue came up?

 

Just to clarify, the T480, T490, and T14 are all having the same issue? Have you tried running the hardware scan from the Lenovo Vantage app? 

 

Could you send us a screenshot of each of the system information, containing the BIOS version and OS version? 

Let us know.

The problem is completely random so it doesn't impact all units.

 

The ones I have seen it on are running Windows 10 1909. Currently, I only have one out in the wild that is reporting this problem. I have not run a scan from the Vantage app. Let me know what specific information I can retrieve to help isolate the problem.

Which model are you having an issue with? When does the throttling happen? Does it happen on a particular app or window? Try running a scan just to make sure there is no hardware failure.
