Automatic white random spots on screen
On booting up the laptop in any mode, random white spots appear and cursor moves and opens applications randomly and automatically. Updated bios, but still facing the same issue.
This piece of cloth which came along with the notebook has properties of a magnet attracting all kinds of particles. I used to keep this between the keyboard and screen, so all the particles on the cloth which were too small to be seen with the eye used to stick to the touch screen due to which it misbehaved. Last evening i cleaned laptop screen properly with a liquid lcd cleaner, powered it up, enabled the HID Compliant Touch Screen & it worked properly. I tested all apps and configurations and all were good. I powered it off and closed the laptop with this piece of cloth between the keyboard and screen. After an hour again i powered it on, and again the ghost touching issue emerged. Then checked the screen with magnifier on mobile and found lots of particles on the screen. That’s when i realized that this piece of cloth was the culprit. All’s well that end’s well. Thanks for your support & suggestions.
This sounds like a malfunctioning touchscreen. The white spots are where the OS is detecting touch input and its providing visual feedback in the form of these white spots.
See if you can disable touch input. That will allow you to bypass the problem for now.
After that you should download HP Image Assistant and get your drivers up to date.
Clean your screen, make sure there's nothing on there that might register as input.
