• This is not a standard single-connector Thunderbolt cable—workstation docks that need full power delivery require the TB3 + Slim Tip split connection.
• Match your original cable label/part number before ordering: 03X7540 / 5C10V25713 / SC10Q68201 / 4X90U90616.
• For best fit, ensure your dock is the ThinkPad Thunderbolt 3 Workstation Dock (DK1841 / SD20M70247) model.
