Is your Arduino working with the computer or it can be stand alone? If you just need the computer to program it and there is no further communication you don't need to keep the USB connected.
Perseverance is 90% of the solution. The remaining 10% is more perseverance.

the screen colour information is getting captured and sent to arduino so that it switches to the right ambilight colours. so the usb connection is very important :-)

Maybe you can make your own box where you connect your USB on one side then the USB going to Ardunino on the other side (small cables though to keep the total distance withing range) and your "inbox" PCB will have a switch attached to interrupt the red wire connection John mentioned. You may have issues with noise though.

But this leaves the arduino still on.


That seems inconsequential compared to the amount of work needed to disconnect / disable the USB power.

Do you really care whether the Arduino is left running?
