The pin is broken in the PSU jack inside the notebook, so I need to purchase a new PSU but am unsure of the part number and how to do it.

Hi @shelleyp , Is this what you mean? (it is not a recommendation to use the supplier. It is merely shown to verify that this is the part that you require) There are other suppliers just search online for VivoBook X202E DC-In jack part to find one that suits you best. Here is a link to a video that shows how to dis-assemble the laptop to gain access to the part, which will need to be unsoldered from the pcb and the replacement soldered on. Hopefully this is of some help.
