[Unboxing photos and measurements here]

In the spirit of the ongoing teardown series, here is the latest installment.

The new Surface Dock 2 is considerably easier to disassemble than the older model due to a simpler approach to fasten the SurflLnk cable. Key changes compared to the old dock are:

• New internal edge style connector for the Lorom SurfLink cable assembly instead of Molex nanopitch

• Cable assembly held in place with 2 Torx T6 screws instead of magnets and glue

• Dock mainboard is ~10mm wider

• Mainboard has one large EM shield instead of 4 small shields

• Metal weights are held in place with screws and adhesive rather than plastic sonic welds

• Realtek Audio with TRRS 3.5mm audio in/out instead of Conexant Audio with TRS 3.5mm audio out
