My PR4100 has stopped working, only sign of life is 4 flashing red lights on the bays. I read that this is caused when the adapter is no longer functioning. What are the ideal replacement adapters online that I should get to replace the faulty one? I’m in the UK. Are they any 19 volt adapters with the correct connection to plug into the back of the PR4100?

Your adapter will have the specs including part number.
Have you tried a web search for “PR4100 power supply”?
First thing I did.
