the power cord has the large block which converts the regular AC 110V to 19V DC but just before the DC jack at the end of the PA is a round, molded plastic ...Thing. does it house a fuse? is it just for holding when disconnecting from the laptop?

It has a ferrite core which helps reduce electrical noise.

It's a shielder. You've probably seen those same "round, molded plastic" pieces that you can put on printer cords and such. It's to shield other cables and equipment from the magnetic field generated by the power cable.

that's a ferrite Bead it particularly is purpose is to decrease digital interference to the computer from the electrical powered twine. as electrical energy passes by a twine it produces an electric container around it. that container would reason intereference with digital instruments. so sure you may decrease the twine in the back of it yet you will would desire to replace the bead as nicely.

It's a static disrupter, it's kinda like a surge protector

I think is similar to surge protector, like a circuit breaker to further protect your computer.

Brian's right on this one. It's a noise filter.

I believe that is a static disrupter, but I could be wrong...
