Hi, I have W540 with windows 8.1 installed and completely updated. The problem is that after the laptop is awaken from sleep, laptop screen won't turn on and I see that laptop is working.
If I have 2 screens connected I see on the second screen that after laptop is awaken from sleep, windows is loaded and ready to enter username and on the primary, laptop screen, is completely turned off. I tried disconnecting cables in order to force laptop to turn on the screen but still nothing. Can you help. Everytime after sleep was used, I need to manually force turn off laptop and then it starts normally and the picture is displayed on the screen.

I know on windows 7, if you have a second screen, the login will only show on the primary monitor.
however, this seems different.
try updating the video drivers for your intel and nvida gpus from
downloadcenter.intel.com and nvidia.com

Hi Hemanth and thank you for your reply. I saw that this thinkpad doen't have Power management installed. Can you please give me links where I can download power management. I could only find SCCM power management which I do not need.
Thanks a lot.
