There's a trick if the machine won't power up at all...

The power switch on the MG1 is software-controlled (!), and it runs off 5
AA NiCd cells on the power distribution board (these also keep the RTC
running). They're charged when the machine is running, but of course if
you leave it powered-down for too long, they go flat, and you can't turn
it on agaain.

The way round this is to connect a 9V battery (a PP3 or similar) to 2 of
the pins of one of the connectors on the power distribution board (I can
get the exact details). The machine will then power up, and you leave it
running until the NiCds are charged

A kludge, sure, but it's better than the Torch XXX where the official
procedure is to replace the PSU assembly if the battery goes flat (!).
