Ok the run down:
Lenovo Thinkpad W541 : 500 GB SSD : 32 GB ram : 3k Display : k2100m Discrete GPU : went from a 4910mq to 4940mx
Acquired said 4940mx from eBay about 5-6 months ago and waited to put it in. Well sat down last night put it in used Arctic Cool 4 thermal paste and it runs even cooler than before it seems never really benched before hand. Figure just do the long tear down be patient and reap the challenge.
Very stable before hand with limited issues from windows 10: Now directly after swap had issues where battery did not want to charge and the screen will go insane. Solution ! Yup a fresh install , Outcome battery works fine screen works till Intel 4600 Drivers get auto updated then goes back to crazy town. Only work around I've come across is to use my dock to other monitors as its stable here, undock screen goes bonkers. So after several formats playing with blocking updates , installing drivers from Intel and Lenovo manually same issue still remains.
Question can the integrated graphics of the CPU be bad? All test i throw at it says its good passes everything no hiccups. If i open device manager disable the Intel 4600 drivers and un dock screen is stable, when formatting and fresh install on generic Microsoft drivers, again stable. The problem imedianlty shows when the Intel 4600 drivers are loaded and yes I tried everyone on there site to see if there was a winner. After much tinkering I turn to you guys and gals for help as I'm no expert.
I can already here someone say did you put the old CPU back in and see if that fixed it ... no not yet the tear down takes a little bit and not convinced its bad unless the integrated graphics can go out. At one point after trying several scenarios when i had it docked i disabled the discrete quadro gpu and it maintained all 3 monitors no issues, this was a big surprise and led me to believe there is hope and that this is some sort of driver error, blip, or workaround.
I'm happy to work on this issue swiftly and can post details for future user issues. thank you for the read please give it some thought.
