My pismo was working perfect one day and the next would not power on. If I attach the power, it does not show the battery receiving any power from it thus not turning on. I have tried other power adapters that are proven to be good power sources but with no luck. Any ideas on where the problem may be?
I had a Pismo conk out on me after having been in storage for a while. In the end, I opened up the machine and replaced the little battery on the logic board and it started back up again. But there are folks online who are saying that you might not even have to replace that battery – just remove it, restart the computer, then plug the battery back in to recharge it. Here’s that thread with all the details: http://forums.macrumors.com/archive/inde… Not sure if this is your problem, since it sounds like your machine hasn’t been in storage. But it might be worth a try!
It sounds like your DC-in board has failed. Unfortunately, iFixit is currently out of stock on this item, but here is the link to the page anyways. You can find the apple Part # and maybe search google to find another site that might have one. [linked product missing or disabled: IF106-003-1]
I had a similar sounding problem with my Pismo, except that the power was intermittent - if I wiggled the power connector I could get it to work. I removed the DC board according to the ifixit repair guide and resoldered the connection between the board and the connector - everything was fine again. I think the years of plugging/unplugging the adapter stressed the connection on the board and/or there was a weak solder joint - it does seem to be a bit of a stress point as the plug fits very tightly. can you get power at all if you gently wiggle the adapter connector when plugged in? if so try resoldering the connector. if not, then as mentioned above it’s likely a bad DC board.
Definitely works unplugging the pram battery! Easy to try and don’t cost anything! Give it a try first :-)
