Re:Bluetooth Mouse Lag / Stutter on Lenovo Yoga 7i 14"

I'm keeping it.  In all fairness, since it seems to be happening to other brands (Dell was mentioned in this thread), I believe it's Intel's latest Bluetooth software that is the problem.

So I have an Thinkpad E14 Gen 2 (Intel i5) with the same problem, and the registry hack resolved it:

 

* Click Windows icon (start)
* Type regedit
* Right click regedit
* Click Run as administrator
* Navigate to =
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_8087&PID_0026\5&ed1e05a&0&10\Device Parameters]
"DeviceSelectiveSuspended"=dword:00000000
"SelectiveSuspendEnabled"=dword:00000000
"SelectiveSuspendSupported"=dword:00000000

 

Just mentioning this, so that people with this laptop can google this solution.

Yes, this has been reported in here already. But this registry hack also leads to probems when waking up from standby. In my case, all Bluetooth devices get disconnected and can't reconnect without turning BT off an on again.

Lenovo Yoga Slim 7i Pro 14" Core I5 11th here.

Same problem. Bluetooth mouse is unusable!

Applying the registry fix +reboot worked, although my reg keys had different IDs.

Two mice, same issue...this is frustrating. Hope this fix stands for now until Intel decides to fix their stuff!

Btw, you won't find too many power management options in Device Manager if your model has Connected Standby enabled, so the reg method is the only workaround for now.

I use a MS Precision mouse and lucky enough it works as wired as well, so until now I used it like that.

Re:Bluetooth Mouse Lag / Stutter on Lenovo Yoga 7i 14"

Excuse me jumping in on this.

 

I have had this mouse lag problem on a recently purchased Lenovo Yoga 7i with an old Lenovo Yoga bluetooth mouse.

On 3/6/21 I noticed I had received an automatic Windows driver update, Intel Corporation - Bluetooth 22.50.0.4.

After installing this update, there was no change. But then after 'removing' the mouse and re-pairing it was almost perfect.

But still a small noticeable lag on first movement.

Might anyone know if this Bluetooth mouse lag issue is an Intel issue, or is it a Lenovo issue? The Lenovo 7i machines we own with the 11th Gen Intel chips, the problem is constant. However, the rest of our Lenovo X1 and Yoga machines with previous generation Intel chips don't have the problem. Currently, it is not clear who is responsible for this. The registry hack may work for some, but this is not what the average person should have to do to get this fixed. A patch should be released that fixes this proven problem by either Lenovo or Intel.

 

Lenovo, if you are monitoring this thread, would you kindly inform us as to who owns this issue? Is it an Intel issue, or is it a Lenovo issue?

With reference to my post yesterday, and after using the mouse today, I am now confident that the installation of the Intel Bluetooth 22.50.0.4 driver update has fixed my particular issue.

 

My issue was that the mouse curser hesitated to get going from rest.  After a few seconds resting it would lag again. Once moving it was OK until the next rest. This became particularly irritating!

 

I hope this clarifies my particular situation.

It's not only the Lenovo Yoga that has the problem. I'm using IdeaPad Slim with 11th gen i5 and having same issue. The registry hack does fix it. So I'm pretty sure this is the problem with Intel 11th gen.

 

Anyone knows how we can report this defect to Intel? We need to escalate this as much as possible because this affects a basic function and it is unacceptable how such a defect can pass quality check to come to end users.

This maybe of interest. The link to intel community appears relevant and current to this issue. Also they have a Moderator involved.

The title of this has had 'Solved' added, but obviously not.
