Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
Hp prime Gen 1 touch screen disabled after updating. This description from archive I think might explain the problem but not solution.
(The problem is that your unit came with a newer firmware, and updating to an older one stopped the touchpanel from working as the older OS doesn't support the touchpanel in your new unit.)
I have tried resetting the calculator which made it unusable as now it is stuck on the welcome screen with non functional touch screen.
current application version 20200116v14425
OS version v0.050.640
I have tried every trick I could find from previous posts including downloading the oldest firmware I could get on the ftp archive but to no avail.
Any help would be appreciated!!
