XPS 15 7590, touchpad does not respond sometimes

I forgot to update my post here after trying out the solution posted by the other user. I noticed that the problem comes back after the laptop is rebooted. I have to complete all the steps in the solution every time after a reboot for it to work.

Still no fix of this from Dell. Getting kind of ridiculous now. Having to hibernate your laptop all the time just to use the trackpad isn't acceptable.

Well it's been over a year now and it's become very clear Dell is never going to fix this. The supposed fix to this is temporary only and resets with every restart. Given how often this thing updates, which never fixes problems and only creates them, you'll be applying the "fix" an awful lot. If they're not going to fix this they could at least have the decency to remove the solved banner from this thread.

Hi, Yes I call the support and no one can tell me how to fix this problem...

I changed the touchpad, the motherboard, the battery and stil doesn't fix it

Hello, yes i have to do that too to solve the problem ! Did you fix it ?

Yes it's not solved....

I opened another thread, Dell still don't want to solve this problem...

same problem here. 

really remarkable that they haven't solve this after so many complaints.

I had a mod message me like half a dozen times to get my service tag. Knowing full well it was out of warranty I ignored them but finally relented. Lo and behold I was told my warranty is no longer valid but rest assured, I could pay for additional support! That proved to me exactly where Dell's priorities lie. I used to really like this laptop and raved about it to everyone, I even gave them a break for months and months to give them time to fix what should be a simple problem. I no longer feel that way. You're right though, it really is remarkable.

I am experiencing the same problem here.
Very unfortunate for a device of +€2,000

It is 100% related to the "Intel(R) Serial IO I2C Host Controller - A369"

Thanks, this worked on my Precision Mobile Workstation 15 5540.

Device Manager | (local) > Human Interface Devices > I2C HID Device

I had two of these listed and applied the setting to both.

I have the same problem on a brand new XPS 15 with a touchscreen, the mentionned fix doesn't even solve the issue anymore, even after a reboot (plus those checkboxes don't persist on reboot).. This is really frustrating. We need a permanent solution

This has to be a driver issue, and cannot be anything else, no amount of hardware change or win reinstall is gonna fix this issue

I have been having this problem occasionally, touchpad sticking and not responding to touch. This fixed it for me:-

plug in a usb mouse to use instead of the touchpad
1 go to device manager

2 select human interface devices

3 right click HID-compliant touch pad, uninstall device

4 right click human interface devices, scan for hardware changes

this will reinstall touchpad and hopefully make it work again. 

Same problem here and my laptop is on the latest software and updates from Microsoft and Dell.

I have the same or similar issue on a Dell 5540.  Seems to be consistently reproducible.  Every time the device goes to sleep and I log back in, the touchpad has about a second delay before it registers any touch events.  The video posted in this thread shows the issue well: https://www.dell.com/community/XPS/Mouse-cursor-quot-freeze-quot-with-touchpad-XPS-15-7590-Windows/m-p/8018991

It seems to be a software issue, because the touchpad works well 100% of the time after a device restart or after restarting the touchpad driver.  Until the device goes to sleep again.

I wanted to share my workarounds (from the help of many people posting here).  To fix the touchpad issue, I have a .bat script that can be run with admin privileges. It disables and re-enables the touchpad.  My file has this code (please verify the '*touch pad*' is appropriate for your device before using):

powershell -command "Get-PnpDevice -FriendlyName '*touch pad*' | Disable-PnpDevice -Confirm:$false; Get-PnpDevice -FriendlyName '*touch pad*' | Enable-PnpDevice -Confirm:$false"

Or to avoid the issue when the device sleeps, I have a .ps1 (powershell) script with the following (please verify the correct instance is found for your device before disabling it with the last two lines):

# find device to disable "Allow the computer to turn off this device to save power" for
$hostController = Get-PnpDevice | where {$_.FriendlyName -eq "Intel(R) Serial IO I2C Host Controller - A369"}
$instanceName = $hostController.InstanceId

# find Windows Management Instrumentation instance
# NOTE: manually verify correct instance is found before using this script
$powerMgmt = Get-WmiObject MSPower_DeviceEnable -Namespace root\wmi | where {$_.InstanceName -like "${instanceName}*"}

# disable "Allow the computer to turn off this device to save power" and save the changes
$powerMgmt.Enable = $False
$powerMgmt.psbase.put()

I have the .ps1 file running "At log on of any user" via Window's Task Scheduler, with "highest privileges".  I do this, because "Allow the computer to turn off this device to save power" is always reset on device restart.  So this script disables that option when I first log on to the device.
