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

2021-01-14, 5:12 AM

Hello!

 

I recently purchased a Lenovo Yoga 7i 14" laptop and even more recently purchased a Bluetooth Microsoft Modern Mouse to go along with it. The mouse constantly lags, stutters, and sometimes shoots across the screen, especially if I don't move it for just a few seconds. I have pretty much ruled out the mouse and am considering returning the machine, even though I really like it otherwise. 

 

I have tried:

  • Disabling "Scroll inactive windows when I hover over them" (some articles/videos suggested trying this, but seemed to be for an older Windows update issue)

  • Changing mouse sensitivity

  • Trying a different Bluetooth mouse (new Logitech mouse), but had the same exact issues 

  • Deleting/reinstalling the Bluetooth mouse drivers

  • Wiping the drive and reinstalling Windows

  • A wireless mouse using an old USB dongle works fine, but I only have one USB port that I would like to use for other things...

  • Running Windows Bluetooth Troubleshooter via settings

  • I even went back to the store and paired my Bluetooth mouse with the same laptop demo model and it had the same exact issue, so it seems there is something wrong with this model that needs to be fixed 
    • I also tried pairing the mouse with other demo models in the store and they did not have the issue (again, I have pretty conclusively ruled out the mouse itself being the issue) 

One key thing to point out that I discovered: If I go to Settings and "Add a Bluetooth or other device" and leave the window up to continuously search for Bluetooth devices the issue completely goes away. To me, this seems to confirm it is not a hardware issue and that there is some setting within the code causing this very annoying problem. Unfortunately, this is not a good solution because these Settings windows cannot be minimized and is really not a desirable solution for a brand new computer that should be working perfectly.

 

Any help would be greatly appreciated and will try any suggestions offered. Thanks so much in advance!

Hello,

 

Clean install did not work.

 

Interestingly, intel automatic drivers did not install the latest version of the WiFi driver.  Manual search for intel AX201 WiFi resulted in manual download of the latest driver.

Driver did not solve issue.

 

I found a reference to this problem in a dell forum.  There they reference (but not link) a lenovo forum post saying to try this registry edit:

 

* 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

 

This should effectively should avoid the BT adapter from dynamically falling asleep.  Give this a try.  It seems to be working for me... but then again, I never can be sure.

I, too, have a similar problem on a Yogo 7i 15". 

 

I am using a Microsoft Bluetooth mouse, which performs better than what DainishDoe has experienced, but it does delay upon use of the mouse. It as if the Yoga quits communicating with the mouse and needs a moment to wake up to the mouse's movement. 

 

If there is a fix for this or some setting adjustment anyone can adjust, I'd appreciate it.

 

Thanks.

Well, after my previous post, I found and ran the Windows 10 Bluetooth troubleshooter in "Settings." After it ran, the tool applied some sort of fix. I am not sure what the fix was but now my Bluetooth mouse seems to be more responsive.

 

To run the troubleshooter, go to "Settings" and then in the search box of that window type in "Find and fix problems with Bluetooth devices." (See pics below.)

Well, I am finding that the problem is really not fixed. I am finding that I need to run the Windows "Find and Fix Bluetooth devices" tool regularly. This means that either Windows is the problem or more likely my Lenovo 7i is the problem. 

 

What specifically occurs is, the Bluetooth mouse seems to hesitate if it sits inactive for more 5 seconds. After running the tool mentioned above, the mouse's response improves a lot. If I restart the PC, it seems I need to run the tool again in order to get the performance to improve. The tool says that it finds and applies a fix but it does not specify what the fix is.

 

Lenovo, is there a driver update needed on the model 7i 2-in-1 (w/ 11 Gen i7 chip) or is an update coming?

Facing the same Issue with a Yoga 7 Slim 14ITL05 82A3 and a Logitech M590, which works perfectly on other devices. Usually there is a energy option for Bluetooth standby, which is not accessible for me ...

I have the exact same problem with my brand new 9i (2021-02-27)

 

I am seriously thinking about returning it!

Same on Yoga 9i.
People have the very same issue on DELL XPS 13 7390, so it seems to be a some generic intel\windows problem.
Everyone suggest to turn off Bluetooth power management, however it does not completely solve the issue (since windows 10 2004 update)
That's especially frustrating while scrolling the page.
Waiting for some Intel Bt - windows BT power update.

Probably it is a chain effect of putting multiple chanined devices to sleep.
Issue is less annoying when power management is turned off for all devices in the connection chain.
