Hi folks! Long time, no type. Like, *really* long time no type. (I just realized I've had an account here for fifteen years!)
Some of you may remember that I used to have a bit of a soft spot for the PowerBook 5300 in all of its terribleness. And I successfully managed to canibalize some partially dead ones into a pretty decent one. (you can see some of the photo progress here: https://www.flickr.com/photos/aminorjourney/albums/72157632263457145 -- I since put everything back together and emigrated to the US fron the UK in the intervening time. I've been 'busy' with other projects).
I managed to salvage a couple of spare power supplies, but I think there's maybe a capacitor problem. Here are the symptoms. 1: Plug Powerbook in. It boots. It's happy. 2: It dies toward the end of the boot cycle, or after a few minutes of use. 3: It doesn't respond to power brick any more. If I wait for a significant amount of time, it does *eventually* reboot, but then does the same thing.
I'm guessing a bad capacitor in the power supply, and I'm not sure if it's actually blown two power supplies which no-longer work. It appears I'm getting voltage at the pins on boot, but then it's dying. (Short?)
My 'less likely' suspects: PRAM battery. I think these wer rechargable on the 5xxx series? The main powerbook (NiCad?) battery died a LONG time ago.
Something fishy with the main board (I don't think there's an issue, because otherwise it wouldn't boot for a short while and then die)
Any thoughts? Also, good to be back :) I've missed y'all :)
