| Powerbook 160/ 165 capacitors |
Posted by: jwse30 on 2020-07-20 22:54:55
So I've been reading about capacitors failing in well, everything Mac made way back when. I see lots of threads (here and elsewhere) about Powerbook 1xx screens needing to be recapped, but I don't see much about the logicboards or anything else under the keys. Are they built with different caps? I saw one thread about a 180 that said it was all solid state, so it had no caps. Is that the case with the 160 and/ or the 165?
Thanks,
J White

There are no electrolytic caps on the mother or daughter boards, just on the trackball assembly, inverter/converter board (for brightness/contrast controls), and the display inverter board.

That probably explains why I've never heard of problems with them š

J White i mean i had a 180 that had a tunnel screen and one that was completely fried so the activematrix screens that tunnel make these useless in my opinionĀ

J White As noted though the screens do need to be recapped. There are 9 plastic encased electrolytics thatĀ 100% for sureĀ are leaking. Ā At lease one of theĀ caps on the inverter is polymer (Oscon) but I usually still replace those as a matter of course.
