Hi All,

First of all, I'm not a techie, I'm a user with a little bit more tech-interest than average. I've posted this question on the user-forum (http://answers.microsoft.com/en-us/windows/forum/windows8_1-tms/touch-screen-stops-after-wake-up-possibly-caused/c2beecb9-5b61-4017-8016-0bccba81f153) but the support engineer suggested to post the question here. So here is my question:

I have an Acer R7-371T convertible touch screen laptop and have been having issues with touch screen malfunction from the start. The problem is that if the PC is enforced into sleep mode the touch screen is not functioning after a wake-up. A reset is the only option.

I discovered that the EAS (Exchange Active Sync) policy enforced by my employer may be the cause of this. Looking at the Exchange policy rules I could not find any reason for this but let me explain what happens:

1. After a clean install of my Laptop there is no issue whatsoever. Personally defined power rules about screen-off and sleep are not causing the no-touchscreen issue and in fact, the laptop is working as it is supposed to work;

2. After installing the EAS mail in the Windows Mail app ("metro", not outlook) the policy of my employer is pushed (and accepted) on my laptop. One of the policy rules is that after five minutes of inactivity the lock-screen is pushed enforcing me to re-enter my password. And within a minute after the lock screen is shown the PC-screen is switched off or at least, seems to be in a resting mdoe. From that moment on, after awaking the laptop, the touch screen is malfunctioning.

Is this a known issue? How can I resolve this? What can I ask my employer to change in the policy to stop this malfunction?

Thanks and best regards,

Ben
