Touchpad lag in Elite Dragonfly

[twelveforty]

Hello,

I have a brand new Dragonfly and have a problem with the touchpad. Often after resuming from standby there is a lag of about 3 seconds using the touchpad. For example, I move my finger on the touchpad and only after 3 seconds the cursor starts responding. To solve the problem I have either to reboot. Sometimes also going to standby and resume fixes it.

I noticed that when this problem manifests itself, an errors appears on the event viewer: 

Source: MTConfig

Error: An attempt to configure the input mode of a multitouch device failed.

All the drivers are updated to the latest version, and so is Windows 10, currently on version 20H2, but the previous version 2004 had the same issue.

Any suggestions? The laptop is brand new and this is very annoying issue indeed.

Thanks.

I contacted HP support who guided me flushed the bios firmware and touchpad driver, it didn't help. The support agent also mentioned many users complained about the similar issue after that windows update. The issue is impossible to reproduce and I noticed the MTConfig error message as well. One thing that worth pointing out: I have two elite dragonfly laptops, different hw configuration, one is i5, the other one is i7. The lower configuration laptop hasn't had any issue so far, no MTConfig message either. Hope that helps.

My Dragonfly is an i5 model, and the issue manifests itself after the laptop went to stand-by by itself. If I trigger the stand-by then the issues does not seem to happen. In fact, my workaround at the moment is to put it on stand-by an wake it up right away.

Incidentally, Dell XPSs are also affected, here a post suggesting a solution (which I have not tried):

Also having this issue - Brand new device. MTCONFIG errors also present in event log. Having one of my employees call HP on the matter today - I'll follow-up in this thread if they give me something that works.

TwelveForty's workaround of restarting the device works for me. Definitely a different device ID - but that wasn't so bad to find. 

My machine is a new dragonfly - I included my device ID below.

My batch file - which needs to be run as admin contains: 

pnputil /restart-device "HID\SYNA30A1&Col02\5&3233afeb&0&0001"

Pause

Well seems like  I no longer hit this problem since I have changed the sleep settings. All I did was setting the sleep-after time to a value different than the monitor-off-after time. Before they were both 5 minutes. I also don't see the MTConfig errors in the event viewer anymore. I'll report if it comes back again.

EDIT: red herring, the problem persists.

Hello have the same problem.

I can solve it temporarly with a reboot  (or an install / uninstall the Synaptic touchpad). 

But my 2 laptops are for my CEO and CTO... So I can't reboot or connect to their PC when I want.

I only have this issues when leaving the sleep mode.

If we can have more help....

Hello,

Still no fix yet? Laptops are mostly unusable for my bosses...

No progress as far as I can tell. My workaround is setting the power button to send the laptop to sleep. When I have the lag, I push that, the laptop goes to sleep, and I push it again right away. The laptop comes back up, and no lag. A few seconds in total, better than rebooting it.
