Macintosh Portable Sad Mac

Fellow collector Mark Johnson has loaned me a couple of power supplies, so I can test my Macintosh Portable. He has lent me a Macintosh Portable power supply and a power supply for one of the PowerBook 100 series.
I had no luck with the Macintosh Portable power supply, it did not do anything and made no noises. This is probably due to the Portables battery being totally flat. The PowerBook 100 series power supply worked well, but the Portable does have a problem. It spat out a load of different Sad Mac error codes whilst making the strange flupping sound.
