ThinkPad T15 gen 2 TrackPoint and Bluetooth mouse hanging

2021-07-06, 16:17 PM

Hello! I have a problem with my ThinkPad T15 gen 2: on the latest Lenovo driver, TrackPoint sometimes hanging and do not work until rebooting. Now I removed Lenovo driver and try to work without it (on Microsoft driver) and it works fine! But without any features... 

 
Another part of this problem: I have an external Bluetooth mouse (Microsoft Designer), and sometimes It’s hanging to! But if I turn it off and then on – it’s starts to work normally until next hanging.

 

Any ideas?

P.S. of course I tried to remove and reinstall drivers, update Windows etc.

Can you try installing the recently released BIOS version  1.40 and you can get it here: https://pcsupport.lenovo.com/ph/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t15-gen-2-type-20w4-20w5/downloads/ds548904-bios-update-utility-bootable-cd-for-windows-10-64-bit-thinkpad-p14s-gen-2-p15s-gen-2-t14-gen-2-t15-gen-2

 

Update us on how it goes.

Hi geovas333!


Welcome to community forums

 

 

Just to make sure, everything is up to date, run the update through the Lenovo Vantage app and install all pending updates.

If the issue is the same.


send a screenshot of the touchpad driver from the device manager and include also a screenshot of the OS version and the BIOS version under the system information?


Let us know.

Hello!

Please look at the screenshots.

 

And now I found that the problem with TrackPoint is most commonly manifests itself then I'm using external bluetooth mouse (but to be 100% confident, I need to work without It a bit more).

It does show that yellow tag in the device manager.

 

Perhaps having that fixed with compatibility to the current build should help.

So what I need to do at this moment?

For example, now I turn off touchpad (in BIOS), but when cursor moving by itself, I just push on touchpad buttons and it stops! Looks like a magic...

OK, I installed new bios three days ago and now I can say that TrackPoint works correctly!

So thank you Jwes_Lenovo for your help!

 

But after all experiments I removed Lenovo applications from TrackPoint and TouchPad configuration menu. Can you explain, how to get it back?

Good to read that all are doing ok.


You can try to reinstall the same driver from the support site; https://support.lenovo.com/us/en

ThinkPad T15 gen 2 TrackPoint and Bluetooth mouse hanging

Based on the past, I'd like to comment that issues with bluetooth mice connectivity (and Intel WAN/BT adapters) can sometimes be solved by disabling power saving completely in properties of bluetooth adapter.
