  • Holy crap! After a LONG time of cycling and trying to recalibrate an aftermarket battery I got with my PowerBook 150, it just shot up from 4 minutes to 40 minutes runtime after a day on charge! May have revived it!!!!
    Gotta love it when your battery capacity goes UP over time.

    Started at 100% with 0 cycles when I got it, dropped steadily down to 69% over the course of 20 cycles, stayed there for a while, although with always quite decent life. Then suddenly jumped to 79% and now today, up to 80%. Hah.

    How does that work? Haha.

    No clue. Best guess is that it’s a cheap aftermarket battery with a pretty dumb BMS? No idea. Wasn’t even supposed to come with a new battery when I bought it, I was shocked when the iBook arrived with a 0 cycle battery. Listing said “battery condition not guaranteed”
    The PowerBook 3400c's power board is right under the trackpad, and as such heats it up quite a bit after running for a while! Heated trackpads should be a real feature, my fingers can get pretty chilly in the basement, and the trackpad actually can help haha.
    I'm really tempted someday to spray paint one of my PowerBooks to be platinum. Would just look so good...
    I think one of my PowerBook 3400 batteries just died... Had it running to archive software and then after shutting it down, it was all of a sudden dead, and it won't charge back up. 1 down, 3 left.

    Never-mind if does hold charge still, but the battery meter on the pack itself acts dead now for some reason…
    I’m waiting for the new year with some good old games of Tetris.3355D18B-5EFC-4671-847A-4206277389C0.jpeg

    I really enjoyed the original background music of the 1980s Mac-Tetris. I am even playing a loop of Russian folk tunes in the background when I play Emacs' built in Tetris (the only one I have installed) to bring me in the right mood :).
    What do you have there? I actually don't know beyond it being an A/UX login window 😅
    I was just playing some loud bassy music on my eMac and noticed the CRT showing some light flicker-like effects. I didn’t put two and two together until it went away when the music stopped. Those are some strong magnets!

    I had 3 eMacs at one point. There was severe bulging caps in the 2004 model one I had.

    At this point it's fair to say any electrolytic capacitor is perfectly capable in ruining your day.:oops:
    Are there some kind of leak proof caps except ceramics/tantalum/polyprop with larger capacitance?:unsure:

    I had a 2001 eMac (1st gen) that was very difficult to use because it would only run when hot, and even then only intermittently. I never figured out exactly what was wrong, but I strongly suspected it was bad caps on the analog board. I would've recapped it, but it's so chock full of them it pretty well scared me away.
    NiMH Batteries are weird. I have a ThinkPad with one, and earlier today it would shut off immediately when the charger was unplugged. I ran the battery recondition utility and now it works again, and appears to be holding great charge.

    ThinkPad is an i1260 if anyone is curious. The battery is an aftermarket pack manufactured by Kahlon. You could get these with NiMH or Lithium batteries, and Kahlon actually claims to still sell these, although now they only list the Lithium version.

    Just life tested it at around an hour and 20 minutes. This morning before the test, it went back into the state of not powering for even a second and I once again had to recalibrate it! And then it gave me that time, how odd.

    A new keyboard and a very great deal of jiggling connectors so they fit just right. It's mostly awful to work on: there's a decent computer underneath, and the desktop version of the same architecture is a really, really nice machine.
    Browsing the forum from my Sawtooth G4 sure is slow, but fun anyway. Gotta do it while it still runs a modern browser!
