I've got a T520 with soldered pin header as in the referenced wiki page,
and I've got a T420 where I had to use 10cm long wires to place the pin

I've got no problems using both devices.
Can you give more information where the system hangs ?
Does it hang in coreboot? Does it occur after hours running the system ?
