XPS 13-9370, mouse cursor lagging and stuttering

Having an issue with my new XPS 9370. Using the touchpad (haven't tried using a mouse with it at all), the mouse cursor sometimes stutters/freezes for a second then keeps going. Happens quite a lot actually. Sometimes it actually stutters multiple times in one swipe on the touchpad but other times it works fine..any ideas on what to do? I don't see any specific touchpad options in windows settings or anything either.. Thanks

I think I have found 2 solutions for this problem, both based on the assumption that it is a CPU management related issue. On simple terms when the CPU is on low usage some Intel technologies will start to “shut down” parts of the CPU.

Both solutions require BIOS changes (F12 on boot)

  1. Disable Intel Speedstep: this will make your CPU run on its base speed (on mine i7 always at 1,8 GHz). On the downside it will make your XPS lose performance (Intel Hyper-Threading should kick in on more demanding taks). I tested it and did NOT notice any lagging and stuttering. Use only if full performance is not a requirement. I am not using this solution since I use a lot of statistical and data analysis applications and did notice performance loss; OR
  2. Disable C-State: This will prevent your XPS to “shut down” parts of CPU during low system usage. My hypothesis is that the problem occurs when these parts of CPU needs to be “waken up” it is taking then too long. On the downside your XPS will consume more energy. This is the solution I have adopted and so far, NO problems.

Both solutions are workarounds (number 2 if proven correct is near optimal). Nevertheless, I urge my US friends to keep up pushing Dell for a definite solution since here in Brazil the support is limited.

I'm using a  XPS 9550 but I'm having an issue with the mouse stuttering then the laptop locking up. Its been doing this since the motherboard was replaced after the Nvdia card blew up last weekend. Dell Support have me on the correct Bios and drivers etc and are still fault finding however I have noticed my issue is only affecting the Left USB and when on charge. After extensive fault finding (stuffing various peripherals into my laptop) the left USB goes defective when the battery is on charge and the temperature on the CPU and GPU are over 50 degrees. 

The right USB remains unaffected in any scenario. 

Just something to try if you are having problems with the laptop freezing and you have a device connected to the left hand side. (charger side)

Sounds like a different issue, since freezing also appears while not on charger.

Good idea! However, I tried both disable C-State and speedstep but the issue still appears.

If you are facing issues with both (C-States and Speedstep) DISABLED make sure no installed software is causing this since Windows will eventually freeze or hang on high softwares loads (it is "natural"), something I barely see on my Macbook Pro. My XPS (with just C-State disabled) does present some lagging during the first seconds while everything is being started up, after 15 or 30 seconds its all good. If it is your case try disabling some startup applications. Remember that if you have disabled Speedstep as well your XPS will be slower tending to freeze more during startup.

I have been having issues with the touchpad freezing for the last few weeks with my Dell XPS 13 (9343)

Was wondering weather it corresponds to the updates pushed out in light of the Spectre and Meltdown scares?

The touchpad appears to freeze with 100% CPU usage



seems to be a different issue, since we have it also with very low CPU usage (under 20%) and even on being idle.




Seems to work with Speedstep DISABLED. Second day without freezing. However only disabling C-State didn't work for me.

It is sad, since i would like to reach the max frequency limits of the CPU during my work.




My problems returned as my first workday after receiving the computer. Hanging and freezing during client's presentations, shame the computer is useless working like this (So C-State solution is out of the table).

Had Dell Brazilian Remote Support check the computer, where several Windows Services where stoped and all Dell standard tests returned normal...But after remote support was over the problem persisted. On a second attempt they monitored the CPU (i7) during stress test and found out that temperatures would reach temperatures above 100 C (212 F) leading then to conclude that the computer had a hardware issue (my Macbook Pro under heavy loads reach 100 maximum without issues nevertheless it is a different older computer i5). For me strange conclusion that this is the source of the problem but...

They will replace or refund me, I am still deciding.

I am using Windows Pro, anyone with Windows Home facing this issue?
