I was repairing my friend's laptop charger and discovered a damaged component. The label on the circuit board reads "2.5D-9".

From the top of the leads layout I'd guess a varistor.

That works, so you can connect the wires instead of swapping the varistor? Or should you go ahead and replace it altogether?

Avoid altering the main power supply unless you're experienced with electrical systems. MOVs serve as a form of surge protection, and bypassing them may damage connected devices, related circuits, or even pose a risk to your safety.
