Screen issue - mouse flickering by itself

[sophielouise995]

Hi all,

I have a display issue with my Spectre x360 Convertible 13-ac0XX and I'm looking for some help.

The issue is a little hard to describe - when first turning on the laptop and loading to the lock screen, the mouse appears to be jittering about - as if it is possessed, the mouse will jump randomly to different parts of the screen and won't stop moving around, and any attempts to use the trackpad or USB mouse become difficult. Touch pressure dots also flicker on the screen as if there were pressure on my display. The only luck I have is restarting the laptop and the problem magically disappears. But sometimes when I turn my laptop on again, the problem reappears.

I cannot think for the life of me what is causing this problem. It happens regardless of whether my laptop is plugged in via AC or with any USB device connected. 

Any help would be appreciated!

@sophielouise995,

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

First, restart the computer and tap on F10 during restart, once on BIOS screen, move the mouse cursor around to check if it works normally, 

If it does, it would confirm a software issue and you follow the below steps if it doesn't work on its a hardware failure and I would suggest a touchpad replacement. 

 
I recommend you to uninstall any generic synaptic drivers showing up for the touchpad (if available) under hidden devices from the device manager: 

• Click Start, point to All Programs, point to Accessories, and then click Command Prompt. 

• At a command prompt, type the following command , and then press ENTER: 

set devmgr_show_nonpresent_devices=1 

• Type the following command a command prompt, and then press ENTER: 

start devmgmt.msc 

• Troubleshoot the devices and drivers in Device Manager. 
  NOTE: Click Show hidden devices on the View menu in Device Manager before you can see devices that are not connected to the computer. 

• When you finish troubleshooting, close Device Manager. 

• Type exit at the command prompt. 
   
  Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices. 

And then download a new version of the synaptic drivers using this link: Click here

Let me know how that pans out. 🙂

I hope you have a good day ahead,
