XPS 9310 - Bluetooth lag with Logitech MX Keys + MX Master 3

Ok, so I did more tests.

With a Logitech UltraThin mouse, I can not reproduce the issue. The mouse connects with an older bluetooth version and does not seem to support bluetooth low energy.

With a HP Spectre 700 mouse, the issue can be reproduced, also 100% on both laptops! The XPS 9310 and the Inspiron 14 5406. It is not unique to Logitech!

So it seems to be an BIOS issue (or hardware issue?) with maybe bluetooth low energy input devices...

Someone from Dell-Cares got in contact with me...but I don't know if that leads to anything. But it is a clear bug in the Dell BIOS or hardware.

I can confirm! It seems to work. Thanks for this tip! I'll keep an eye on it for the next few days, but for now it really looks like the problem is solved.

I changed the first one to 0, added the others and restarted.

I've been having this problem with my razer book 13 and have been looking all over for a solution, it's been driving me crazy. So far your fix has worked! I made an account just to say thanks!

Someone posted on Lenovo forum about changing registry, it seems work.

[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

=========================

Good work.

Looks like there was 2 different problems presented in this thread.

One was wireless drivers. The WiFi and Bluetooth radios were apparently conflicting with each other on 2.4ghz.

This other problem appears to be the Bluetooth radio not waking-up properly or falling-asleep unintentionally. This was a problem back in Windows-8 days, but forcing the Power-Saving DISABLED on the Bluetooth radio (in Device Manager) seemed to fix it. It was fixed for years. Seems to have resurfaced with recent Windows-10 sleep-mode enhancements or possibly on these recent Intel chipsets and drivers.

I too was having this issue but I'm on a completely different laptop: Lenovo ThinkBook 13s Gen 2 (G2) with 11th gen Intel i7 processor. I tried the registry edit and it seemed to have fixed the issue so far. For me, however, the folder under VID_8087&PID_0026 was a slightly different name and I was missing the SelectiveSuspendEnabled and SelectiveSuspendSupported entries so I added those and set them to 0 as well as DeviceSelectiveSuspended. I'm curious to know where did the original answer come from? I saw someone mention it was in a Lenovo forum but I've searched for this issue all over and I couldn't find it anywhere and just so happened to stumble on this thread! 

Ok thanks, No wonder I couldn't find it! In any case, it has been working well so far. Hopefully Windows/Intel gets their act together and fixes this for good!

Yep that's the one, and they said it's basically a driver's bug from Intel AX201.

Hi, thank you for the tips. The name of the folder on my PC is :

"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_8087&PID_0026\5&6f4654f&0&10". I just have this entry "DeviceSelectiveSuspended" > I put 0 and nothing happen.  

How I can add "SelectiveSuspendEnabled" and "SelectiveSuspendSupported" and put the value to 0 ?

Okay, let's try !
