Power Brick has loose connection
My Framework Laptop 13 charger stopped working and I realized that it was not because of the USB-C power cable nor the detachable AC chord but the brick itself. The port probably has a loose connection or I've bent it somehow. Unfortunately Framework no longer sells the brick by itself and you can only buy the whole charging set, so like the brick, USB-C cable and AC chord. It's also worth mentioning that the charging set was previously out of stock for a good while. :(
Is this a good question?
