chekmate1984 Posted September 3, 2018 Posted September 3, 2018 Hi all we have windows 10 on desktops and promethean active panel screens all over I have 5 or so classrooms where soon as user touches the screen it just locks out the user and they have to log back on. It doesnt fully log them off just locks the screen. Desktops have latest windows updates, the board has latest firmware and and software installed. Has anyone had this issue in past or know what can be causing this? We have rebuilt machine and even swapped desktops and place in a working room and come to conclusion its something with board that's causing the issue as a working
phillyrovers Posted September 3, 2018 Posted September 3, 2018 Hi @chekmate1984, I doubt that its the panel causing the issue. It's more likely that the computer thinks that the "touch input" is you wanting to lock the screen. There is a thread from HP here that describes this exact issue with other touch screens: https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/Touch-screen-issues-goes-to-lock-screen/td-p/6381852 and another with Surface Pro5: https://superuser.com/questions/1259289/surface-pro5-locks-when-i-use-touch-screen-or-pen I'm not sure if your machines are HP, but it appears that some chipset updates might have done the trick here. If you go through your power settings and turn any otion that might lock the screen to off and see if that clears it up as well. Thanks
chekmate1984 Posted September 3, 2018 Author Posted September 3, 2018 We do have HP machines Its not power settings because i can login and straight away if i touch screen it will just lock out. If i unlock and touch screen again it will lock again so only happens if i touch promethean screen. If i move mouse and type anything on keyboard, it does not lock. I will have look at the HP links. I can see HP Image Enhancement for System Logon resolves the issue for few users on link but that software is not listed under the model of PC we have. HP ProDesk 400 G3. We have updated chipset etc but will have look to see if i can do anything else Thanks
hyb80 Posted October 11, 2018 Posted October 11, 2018 Any luck this this? We have had this for over a year and the only solution I found was to uninstall / install the active driver depending on whether it is installed.
markiof Posted October 12, 2018 Posted October 12, 2018 Hi @hyb80 Have you tried what @phillyrovers suggested? Did that work for you or not? What version of Activdriver do you have?
