A bit of an odd one here. A mate has a computer with windows 7 64bit installed and been having a problem he never experienced before: the power management wont turn off monitors after the time he set it up to do. Even when he installed a third party app to turn off monitors with a click they turn back on again right away. So something is actively turning the monitors back on. Now the funny thing is, when he installed windows 8, it did not have any problems. Only on windows 7. So I assume that the monitors are not at fault. He has also tried switching off the network, mouse and keyboard power management wake up, and still wont they won't power off. Any thoughts?
