Repair

A common problem with A4000D is the leakage of their barrel batteries (see here for an example), which damages the motherboard and leads to non-functional clocks or, worst, non-functional A4000! These batteries must be replaced and the motherboards fixed... Difficult jobs! Fortunately, the modern Web helps greatly with Web sites to explore, search, zoom on any Amiga motherboards, the Amiga PCB Explorer, and to access all the schematics of the different Amigas, the AmigaWiki... Cheers to them .

There are also efforts to produce new (improved) motherboards for the A4000D, two in fact:

1. The Alice project with blue, ATX-size motherboard.
2. The Replica project with red, exact replicas of the motherboard.
