What's this green liquid coming out of my Macintosh Classic?

[iBlazed]

A while back I posted a thread about my Mac Classic not working and a checkerboard pattern on the screen. I never got around to trying to repair it because I wasn't yet able to obtain a screwdriver long enough to unscrew the two main screws on the top of the case. Today I approached the computer, tipped it over, and noticed this green liquid coming out of the holes on the bottom. I'm assuming this is why my computer isn't working, but what is it and what component is it leaking out of?

Hello, iBlazed!

From the looks of the liquid, the only thing that comes to mind with a yellow-green liquid is maybe some electrolytic fluid from a busted capacitor? Although the "fluid" would normally just look like some sort of corrosion from the capacitor.

Honestly, it beats me.

Have you opened the Classic up yet for any further investigation?

Thanks!

Edit: Apologies! I've just noticed that you said you didn't yet have a long enough screwdriver to open your Classic!

Looks like now more than ever I need to obtain that screwdriver. I want to save this Mac.

Battery on the logicboard.

Battery on the logicboard.

Are those easy to find replacements for?

Yes, but repairing the logicboard is the more troublesome task.

Maybe the battery leak didn't damage the logic board?

I'd like to say yes.

Unless you're great with a soldering iron and very patient, I'm going to say that the logic boards is a goner. That liquid is almost certainly the fairly corrosive battery acid that is famous for destroying logic boards in vintage Macs.

It's green because it's dissolved some of the PCB into it, sadly.

So.... macquarium then?

This is very sad.

Investigate first, decide later.

Probably, but there is still hope. I acquired a number of old Powerbooks recently and many of those had leaking PRAM batteries in addition to leaking main batteries. One of the worst affected still chimes and seems to boot although I have not got the display to work yet. Another with extensive leakage all over the PCB and into the main battery compartment seems none the worse for wear and work. It will be a job and a half to clean/scrape the others to cross off short-circuits as a reason for malfunctions.
