When I put my laptop to sleep or it sits idle for a period of time and goes to sleep on it's own it stops recognizing the laptop monitor. It will still display on other monitors connected through the docking station, but not the laptop. It doesn't matter if I put it to sleep while on the dock or off the dock, it never recognizes the monitor.
I have an Intel HD Grpahics 4600, and an NVIDIA Quadro K1100M video cards. I've checked drivers for both and they both say they are up to date (9/29/14 for Intel, and 09/12/2014 for NVIDIA). I have also updated every possible thing in the Lenovo System Update.
This problem occured after switching from windows 7 to windows 8.1. I've looked at other similar issues in the forums that seem to revolve around updating drivers to solve the problem, so I've done as much of that as I know how to.
I have also lost the ability to control the brightness of my laptop monitor through my computer at any point in time. The function keys don't work, and the setting is not shown on my power manager.
If you need additional information just let me know, and any help is much appreciated.

I actually ended up having to install an OLDER driver.
one of the people on another thread posted this link, and it's the only one that made anything better for me. I hope it also helps you.

So I just upgraded my brand new W540 from Win 7 to Win8.1 and I ran into the same issue. Proble is now the 5/21/14 intel graphics driver has been taken down from the Intel driver website
Can anybody tell me where I can get this??

Uninstall in Device Manager the "Intel HD Graphics 4600" Then install this driver. I found this on another forum and it worked for me. Driver version 6.16.00.3137

I tried this but unfortunately my w540 must be an oddball. When I try to install this older driver I get a message that says "This computer does not meet the minimum requirements for installing the software"

This is ABSOLUTELY the correct solution. The original posted link works, you just have to uninstal the current driver first and be sure to restart you computer before installing the new one. I've been searching for this solution for 2 months!
