Check the PRAM battery is good, and replace if

Yes, at the Mac shop, this made 98% of dead Macs come alive.
Apple got sued at the time, because the solution in the manual was
"replace the main board" for hundreds of dollars, instead of, replace
the PRAM battery, for seven dollars.
Ultimately, yes, it needs a new battery but in my experience replacing
the PRAM battery with a fresh one doesn't always work straight off the
bat - went through this with a 7300, 9600 and a G3 Blue, all needed
leaving to forget their PRAM settings before they'd power on. *Then*
when you power off and fit the new battery tgey work fine. Back in the
days when I used to hang around on the PCI PowerMacs list and the
G-List at LowEndMac this was a well known proceedure and got repeated
to people who'd already replaced the PRAM battery many times. I have
to admit I panicked the first time it happened to me on my 7300 but an
experienced tech told me how to fix it.
In Apple's defence, the difference between a dead PRAM battery/corrupt
PRAM and the symptoms of a board failure are indistinguishable, hence
why a lot of people think the machine is dead when it actually isn't.
They should at least have issued an adendum, however, so the law suit
was appropriate.

Absolutely. We used to leave them overnight, with no battery...

Yeah. They must have known about it, it had been going on for years.
After dealing with them back in the day (this was in the lost years
without Jobs when they couldn't come up with a new OS and were going
slowly broke) I have no sympathy for them what-so-ever. (;
(I remember incidents like customers having to wait 14 MONTHS for a
motherboard, which was on a Mac under warranty. Guess who took the
shouting for that? Not Apple.)
