I have Lenovo ThinkPad T450s 20BW-S2KM with I7-5600 12GB DDR3 512SSD, and i have problem with display flickerng, fast vertical lines shows on display, appear on the screen line in a split second, when desabled Intel 5500 no more then problem but windows and another program not working properly.
I tried to change all versions of drivers, reintall windows 10, now I install windows 8.1 but I have same problem.
Problems not constant, alternately appear, and disappear, or seem daunting, the computer can be used normally.
The computer is still under warranty, what do you propose to do?
