Help with Fn F3 to turn off the display

I have not been able to get this function to work for a while. I would like to turn off the display while encoding or folding. I called tech support and they said that even though I had the three year on-site warranty, I would have to pay to get that function fixed since it was a software issue. When I try to turn off the display using Fn-F3 and turn off the display, the display turns off and then turns right back on. Anyone have any insight on how I can fix this problem? The latest drivers are installed. I am ticked that they won't fix an existing problem on an in-warranty laptop. Thanks in advance for any assistance.

Would you kindly mention which version of Windows you're using? Windows Vista or XP? Is it an oem factory install from lenovo or a retail version of Windows?.

For what it matters, if you move the UltraNav instantaneously after pressing Fn+F3, it will turn back on promptly.

I am running Windows XP on the original factory install. I am not moving the trackpoint or the pad. Thanks.

There is probably some process preventing the display from turning off. Take a look in Event Viewer for an event at the time that you press Fn + F3. Go to Start > Control Panel > Administrative Tools > Event Viewer. You could also look at the processes using CPU cycles in Task Manager and possibly get a clue there. Press Ctrl + Alt + Del to open Task Manager.

I had the same problem. For me turned out to be the networking component of Windows Media Player. Amazon Unbox was loading it.
