Dead PowerBook G3 Psimo

[bubbahotep68]

I have an old PowerBook G3 that I know worked through 2010 because I set it up for my nephew. I found it a couple of years ago and was hoping it would still boot, but it doesn't. No power situation. I think the yo-yo power adapter works, but the batteries don't seem to charge.

Would a dead PRAM battery prevent the PowerBook from booting and/or charging the main battery? I would be willing to replace that battery.

Thoughts?

Pull the PRAM battery out and then try booting again; your date and time will need to be set right, and won't hold without that battery.
If the battery is really dead the Pismo won't boot.

If you are brave enough, start the Pismo with the keyboard out (but still connected), and then plug the battery in.
If you put the keyboard back in place and leave the system running for quite a few hours it's possible the PRAM battery will take a charge.
From then on your Pismo may be OK both booting and holding the date/time info, but you will need to run it regularly for a few hours to maintain the charge.

Quite difficult to find these days, part numbers 922-3829 or 616-0108

So it isn't a regular battery you can find on the street?

May be still possible to find, but remember it's from a 20+ year old machine.

Try putting those part numbers into an eBay search.

I have a couple of spares salvaged from broken Pismos, but I can only post them out if you are in the UK, and I can't be certain they will hold a charge.

You will find it almost impossible to find one, especially in working condition. Your best bet is to take a modelling knife to the brown covering, look at what rechargeable button battery is underneath and solder your own onto the cable.

Top tip, if you are going to use the Pismo with the internet, date and time can be set automatically from the time servers in the System Settings. They just take a few seconds to kick in after booting up to the Desktop. If you aren't bothered about the internet, date and time don't matter much.
