I recently did a complete format and reinstall of windows 10 . As soon s i reinstalled windows the touchscreen started detecting erratic touches . It detects rapid touches on the top right part of screen and causes a lot of frustration. As a temporary measure i have disabled the touch screen driver for the time being,
Now , I did a lot of research on this issue. There are only 3 possible causes
- Hardware Failure
- Outdated BIOS drivers
- Missing touchscreen firmware driver
The first two can be eliminated as the touch started malfunctioning only after the reinstall and the BIOS drivers are already updated. I don't have the touchscreen firmware driver. I looked for it on hp driver site but it was not listed there.It would be really helpful if i could get the drivers for my notebook.

Thank you for posting your query on HP Community,
The best way to identify if this is either a hardware or a software issue is by checking if the Touch is working on BIOS screen
(Accessed by tapping on F10 while restarting the computer).
If it works on bios, it's a software issue: In this scenario, I would suggest here is to reinstall the display drivers, along with this I would suggest here is to update the Bios and Chipset drivers from our HP support website, using this link.
Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
Refer this link to know how to use HP support assistant.
If the issue persists, Attempt to run a test using the HP hardware diagnostic tool,
The touchscreen test can be reached by following the below steps:
NOTE: If the touchscreen test option is still absent then please download and install the HP UEFI Hardware Diagnostics menu via this link.The laptop needs to be restarted once the installation is complete. Then you may once again try to run the hardware tests.
- Shutdown the laptop.
Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
On the main menu, click Component Tests.
Figure : Selecting Component Tests from the main menu
The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.
Figure : Sample list of Component Tests
- Inside the component test, you should see an option for the Touch Screen Test - Quick interactive test to determine if the touch screen is functioning correctly. To run the test, click Touch Screen, and then click Run once.
Alternatively, I would suggest you go through the steps suggested in the support document for - HP PCs - Troubleshooting Touch Screen Issues (Windows 10, 😎
