Powermac G4 MDD No Power

[hukfin]

Hi all,
I have a 2002-2003 G4 MDD that won't turn on. It's been sitting for about a year and booted fine then but I tried it today and nothing, absolutely nothing. No fans , no motherboard lights, no sounds. This is a power supply issue right?

Thanks for any help!

Hello and welcome.

I could be the power supply or the 3.6 V lithium ½AA PRAM battery on the logic board (usually pink/green or white/green). The batteries are pretty inexpensive, so you could try that first.

Hi Cory,
Thank you for the reply. Yeah, I tried a pram battery first and that didn't help. I remembered I had another MDD with a working power supply but other issues so I swapped them and that did the trick, working now. I wish replacement PS's weren't so expensive now.
