Unplugs can be replaced with a few different synonyms that are still specific to the act of disconnecting something from a power source. One option is "disconnects," which means to separate or break the connection between two things. Another possibility is "unhooks," which refers to removing a hook or fastener that is attached to something. "Detaches" is also a viable synonym, meaning to separate or remove something from a larger object or system. Lastly, "unwinds" could work in certain contexts, particularly when referring to unplugging a cord or cable that has been tangled or wrapped up around something else.
