Hello!
I have problems with HP ProOne 400 G2 20-in Non-Touch AiO. If activboard is plugged in via usb, there is almost no way to normal reboot or bootup a system. Pc starts and there is blank screen. Three lights on keyboard blinks up like pc starts but it repeats like every 30 seconds untill i pull out usb cable connected to activboard.
After usb disconnection there is no problem with boot. I have tried on all usb ports, but there is same problem.
I have disabled Securebood, fastboot, disabled usb boot, and another settings, without any changes in problem.
Bios is the latest,
C:\Users\user>wmic bios get smbiosbiosversion
SMBIOSBIOSVersion
N13 Ver. 02.07
All drivers are latest.
I also have tried with older products (HP/Lenovo/Standard PC). These products have no issues with activboard.
I guess there is problem with BIOS, it seems system doesnt boot up to POST. There is no POST signal (HP Logo) untill i disconnect activboard. Another usb peripherals works without no issue.
Activboard system is promethean Abv378 PRo
