Yes I do have the same issue. using a Lenovo B50-80, started just after the last recent update to:
Linux lenovob50-80 4.15.0-44-generic #47-Ubuntu SMP Mon Jan 14 11:26:59 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
on a docking station closed lid, used to work fine now I have to keep the lid open. and if the lid is closed the PC freezes and would have to hard restart it.
