Hi everyone,
I know this is a post-OS9 computer, but i think we have enough mac enthusiasts here who appreciate legacy OSX hardware too so I'm going to pose this question.
I've opened up my 12" G4 1ghz so far. I have a 1.0, 1.33 and now a 1.5ghz 12" powerbook (several "for parts" units to make 1-2 100% restored)
I'm trying to pimp out the 1.5ghz unit. However all three of them show that they have dead backup batteries for clock. I opened the slowest of the three since that's pretty much going to be the "for parts" (slow man on the totem pole) and i was optimistic that i'd find a user replaceable battery, but no dice. it's this small battery soldered on. i can't find any online references of what this battery is. nothing on ebay and no luck googling in general.
I'm also seeing if this is something that would require the logic board be completely removed to change or if it's a surface soldered piece? probably taking it to a local professional to have the work done once i know i have the right part.
Thanks!
Caleb
