Here's how to keep your AC adaptor in good condition. Repeatedly bending the cable strain relief will weaken it. Wrap the cable loosely keeping the strain relief straight.
Be careful when placing your adaptor adaptor on the floor. Treading on the cable or running over it with your chair will cause damage over time. The centre pin on barrel connectors can be damaged if you plug them in incorrectly.
Turn your laptop so you can see the port when plugging it in. Thanks for watching.
