Hey all,

I'm a newbie to the Mac world, been troubleshooting desktop PC's for a while, but hve yet to venture into the laptop/notebook realm, especially where Macs are concerned.

I just got a 12" G3 700 MHZ iBook for free, but it won't power on. Absolutely nothing. I found that my charger was bad by using a friend's charger, and my battery works fine on another (G4) iBook, so I know it's not a problem with the battery or the power adapter.

I've read tht there's extensive problems with the logic boards on these models - is that my next step? Is there any other (preferably cheap) possible solution? I've also tried resetting the PRAM, that did no good either.

Thanks in advance!

try resetting the PMU

Just tried the:

Shift-Control-Option-Power method of clearing the PMU, didn't make a difference.

(I checked, and mine doesn't have a reset button - but isn't this function dependent on a source of power?)

How common is it for the Power Input Board to be faulty?

I just tried applying pressure to the case to the left of the trackpad to make sure the GPU is getting a connection, and that hasn't worked either.
