It most often happens when the USB-C power cable is connected or disconnected and the laptop is left idle for a while.
#BLUETOOTH MOUSE LAGGY BLUETOOTH#
In addition to the Bluetooth lag, my touchpad stops working sometimes and may or may not wake up from its stupor if I wildly pass my fingers back and forth across its surface. My 9310 has had power issues from day one. I too am having the exact same issue with my two Bluetooth mice (MX Master 3 and M535). It's a great summary of what people have found so far. Not a big deal if there's one shock, but the whole day's worth accumulates and wears you down. It may seem like a minor thing, but it's like getting repeatedly shocked with static over and over all day. I challenge anyone to deal with this through a work day and not be totally frustrated. As of this moment, I'm quite confident that a solution is not known. It's clearly a problem with the XPS 9310. Rolling back to a fairly old version of Windows (1904).Toggling the option "Scroll Inactive Windows".Turning off the option "Allow the computer to turn off this device to save power." At various levels in the Device Manager chain of devices:.In an effort to collate all potential solutions, here are links to things I’ve tried without effect: It seems to have ruled out the pointing device and Logitech drivers, which are the only other things I can see causing problems. None of the above pointed to anything other than on-board bluetooth/OS combination. Disabled internal Bluetooth and used an external USB Bluetooth adapter.Connected another Bluetooth pointing device to the XPS 9310 (Logitech ERGO M575), same issues.Connected the Logitech MX Ergo to other computers via Bluetooth (Precision 5540 and XPS 9650), no issues.Connected the Logitech MX Ergo to the XPS 9310 via Unifying Receiver, no issues.In an effort to isolate the portion of the system that is failing, I tried the following A-B comparisons:
#BLUETOOTH MOUSE LAGGY DRIVERS#
Didn't use Dell's driver sets, instead downloaded drivers directly from vendor websites (Killer, Intel, etc.).Tried using the Killer (Rebrand) versions of the drivers.Tried using the Intel (Manufacturer) versions of the drivers.

#BLUETOOTH MOUSE LAGGY UPDATE#
Ran Dell Update to make sure I have the latest drivers, BIOS, etc.To make sure all of my firmware/software was in line I performed the following: This same behavior has been seen elsewhere: If the pointer goes idle (doesn't move) for a period greater than a second, there is some probability that when I start to move the pointer again it will be frozen for a period greater than a fraction of a second, as much as several seconds. The pointer will function as normal as long as it keeps moving. I've read some suggestions about modifying the Bluetooth Collaboration setting under the NIC but the new Killer NIC's don't appear to have that setting in Device Manager.I am having trouble keeping the connection to my Bluetooth pointing device (Logitech MX Ergo) alive and functional. The same BT mouse works normally on my other 2 in 1. It will continue to move smoothly as long as I don't stop but if I stop, the cursor will exhibit the same initial movement lag. I'm experiencing an issue where the mouse pointer takes a second to move after I start moving the BT mouse. Is anyone else having Bluetooth mouse lag issues with new 2 in 1? This is a brand new set i am using my BT mouse.
