Hi Iru, 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 header near the RAM slots to make it accessible through the bottom flap.
I never solder pins on T420, and have no such problem. Maybe there's something to do with my soldering skills.
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 ?
The machine boots fine to Linux, but it can freeze after some time, and I can't predict when this will happen.

Hi community,
I've had this problem for a long time, but I don't feel like to ask it until some one ask me about this problem.
Lenovo T520 has a BIOS chip under the magnesium structure frame, and it may have a WSON package, so I solder a pin connector at the `J100' solder place. (https://www.coreboot.org/Board:lenovo/t520#Flashing) However, I don't know whether it can cause problems. I flashed two pieces of T520 mainboard (without nVIDIA GPU) before, and after it had coreboot installed, the system could hang randomly, I don't know what had happened. I hadn't tested it with the pin connector soldered and factory firmwae.
So I hope some one with this laptop can report some status in using.
Regards, Iru
