I recently got a Pismo (with a 500MHz PPC7410 upgrade!) but it's...seemingly completely dead? Plugging in my 45W yo-yo adapter does absolutely nothing, neither does the key combination for a PRAM reset. Is something fried? Do I need a different power adapter?

Disconnect the PRAM battery and try to power it up?

PowerBook G3 Pismo Troubleshooting
The Pismo looks like the Wallstreet and Lombard, but has a Firewire 400 port. Troubleshooting is fairly straightforward.

The 500Mhz CPU is nice! They're quite hard to find now.
I'm pretty sure the power cards fail on the Pismo often. I had the same issue, no power or signs of life but after replacing the power card from another Pismo (working) it booted normally. It would be worth re-capping the machine as this is probably where the problem is coming from.
Trying another power adapter is a good place to start, otherwise either a new power card or re-capping might bring it back to life.

Is it? I’m not aware of these using electrolytic capacitors.

I had a Pismo with a standard G3 400 Mhz daugtherboard with booting problems, I carefully removed the board and inspected it..two little pins were ever so slightly crooked, I carefully bent it back..it never booted again..temper temper
I hate those connector boards, the latest 500 mhz models had better ones

Bummer. I have had to replace the "power in" (DC jack) board on one of mine. Not sure if this is the exact one, but similar to this :

Not sure they are interchangeable? Perhaps someone following this thread will know?

There's at least one on the logic board near the PCMCIA slot, and three on the underside of the power card
