Maybe a bit hard and I don't know if it should produce a connect/disconnect chime or not if it were being used (which I know it isn't), but perhaps check if the docking station connector on the bottom of the laptop (and motherboard) is OK.

If you haven't already done so and maybe it's a bit hard and also I don't know if it should produce a connect/disconnect chime or not if it were being used (which I know it isn't), but perhaps check if the docking station connector on the bottom of the laptop (and motherboard) is OK.
If it appears OK then here's the [link|https://download.lenovo.com/pccbbs/mobiles_pdf/p50_hmm_en_sp40j71944.pdf|hardware maintenance manual] for the laptop and if the motherboard is an NM-A451, the motherboard [document|31515|schematics] that may help.
