I have a brand new Lenovo Thinkpad t440s and I installed a samsung 840 EVO three days ago. I have Windows 7 that came with the laptop but i'm not sure if this post should be moved to another area of this forum. Everything works fine but when I click "Shut down" from the start menu button it looks like the computer starts do turn off but stops mid-way. The deskop icons disappear but I can still see my wallpaper. I can't go to task manager or do anything so I always have to hold down the power button to shut it off. Do I have to do anything in BIOS to fix this? I also tried just closing it after pressing "shut down" but the power is still on. When I then open it up the screen is just black (but still turned on). Please help
