I have set my screen saver to start after 3 minutes, however when I'm away from office and come back, the screen saver has not started. The screen saver is set to Blank, and I've tried other screen-savers as well. How can I investigate what holds it back from triggering? I know my Windows Media Player is set to "allow screen saver during playback", and this is not related to that as this also happens when wmplayer.exe is not running. Other programs I run: Remote Desktop, Lync, Outlook, OneNote. I set this to Security, because my job is IT and my account have access to *all* company data/folders.

Hi HAL07, Try the following if the screen saver does not work. Unplug any external hard drive. Check for optional updates on WU Check the logon screen option. Kill the wake-on settings in the advanced NIC properties/settings. DEVICE MANAGER- NETWORK ADAPTER- (Right-Click Network Card)- PROPERTIES- POWER MANAGEMENT- Disable, or uncheck box: Allow this device to wake the computer DEVICE MANAGER- DISPLAY ADAPTER- (Right-Click Display Adapter)- PROPERTIES- DRIVER- Update Driver Software. If you use Microsoft keyboard/mouse: Downloaded the "Microsoft - Other hardware - HID Non-User Input Data Filter (KB 911895)" update.
