Lenovo X240 ThinkPad motherboard replacement

All USB ports malfunction and system hanged frequently in my old Lenovo X240 ThinkPad (i7-4600U). So decide to replace the X240 motherboard (system board). It is similar for X250 and X260 series Lenovo notebook.
It used HK$380 to order a X240 motherboard (Sure it is not a new one since X240 already stopped selling for a long time). Luckily, it is working properly and same after the replacement.
