Got an Amiga 4000 in the shed, aint been stoked up for years, all wrapped up in its original carton.
Peter - maybe take it out of its wrapper and check the NiCd backup battery - to quote Wiki:

The NiCd backup battery is one of the most common causes of problems in an aging A4000 because it has a tendency to eventually leak. The released fluids are somewhat corrosive and can eventually damage the motherboard.
