2013 14" Lenovo Thinkpad L440 [4th,2C,M] + GTX 1060 @4Gbps-EC2 (EXP GDC 8.x) + Win10 [sabrefv]
Problem number 1 - Black screen when boot PC with Express card plugged in with EXP GDC Beast connected. Remove express card and it boots no problem. Go into Windows and hot plug Express Card and it recognizes the GTX 1060 every time.
I have set the EXP GDC beast PWR ATX switch to off - When the PC boots it recognizes the GDC beast and turns it on but still black screen with no posts at all
I have set the EXP GDC beast PWR ATX switch to on to leave it always on and still I get a black screen
Problem 2 - when I hot plug the express card it recognizes the card but gives and error 12
Do I need to do a dsdt override? Or can I just use eGPU setup 1.35? Really dont want to do all that is described in the DSDT override.
There is an existing L440 build which implemented a DSDT override to overcome error 12:
