    macintosh iici weird power supply behaviour

    hello everyone, it's been a while. but to my point: i recently received a iici from an seller in my country that was described as 'macintosh for sale working plays music on power up'. i immediately thought that at least it's doing something, and if the chime is the happy mac one, i'm all set...

    weird ibook problem

    wow, thank you. you sure beat me at finding nice ebay auctions. :)) sadly, most of them only ship to the us, but i'll arrange something. :) i'll go along with your suggestion, too, i'm not getting rid of the duo. it's been with me for 10 years now, after all. however, i'll post a new thread...

    weird ibook problem

    thank you. i'm determined to making this machine working again. it still runs tiger (the best release mac os x so far in my opinion) quite nicely, and it'll be the perfect laptop for my mother. ;) anyway, i'll make a post about the duo then. i love it, but it's almost useless without a duo...

    weird ibook problem

    oh, just a quick last question: do you think a completely working powerbook duo 2300c (with charger and a battery that still holds charge for 30-40 minutes) for a g3 ibook is a fair trade? i'd like to get my hands on one of the latest laptops that can still run os 9 natively. mainly for taking...

    weird ibook problem

    i think not. ;) and it didn't work for the guy in the article. anyway, i've succeeded, with a joint solution. there are two chips above the bigger one with the 'ati' label, and the right one remained sensitive to the touch. if i pressed down on it, the machine would boot normally. otherwise...

    weird ibook problem

    okay, i'm through with two burning sessions, and it works, but only partly. if i press gently on the gpu chip, it stil goes blank. i've noticed that the alcohol i'm using is only 70% pure, it's hard to set on fire, and it burns with almost no flame. i'm considering benzine, although that might...

    weird ibook problem

    then burning it shall be. :) the machine is broken down to bits, i have nice, clean access to the gpu. it's hard to miss, since it has a nice 'ati' logo on top. i'm assuming that i have to place the candle light on the top as opposed to the bottom seen in the burning 'tutorial'. the g4 ibooks...

    weird ibook problem

    update 2: pressing down on the heatsink did the job. as soon as i let go, the screen went blank. this leaves me with two questions: 1: did i actually press the gpu against the mainboard, thus connecting something that's loose, or did the motherboard sink deeper into the tablecloth, thus...

    weird ibook problem

    update: i tried to manually apply pressure (like shimming) to the chip while turning on the machine, but it had no effect: nothing on the screen, but the computer was booting nicely (i coud hear the hard drive working and even the silent hissing sound when the sound came on (typically this is...

    weird ibook problem

    i took it apart and did a test. if i press down on the mainboard, where the main display connector is (left of the area between the keyboard and the trackpad) it works well. if i let go - blank screen. so this has to do with the video chip. i'm assuming that since in the burning 'tutorial' the...

    weird ibook problem

    thanks for the detailed reply. :) i'm not entirely sure what you meant by 'scraping the laminate off', though. i've never had a problem with a gray screen. it always consistently goes blank. sometimes, even after the boot chime. if so, there's sometimes hd activity, sometimes nothing. the fan...

    weird ibook problem

    hahaha, thank you. :) i knew about this, even read the article, but - for some reason - thought only g3 ibooks are affected. well, i guess it's time to open her up again - this time for a hot ride. :))

    weird ibook problem

    hi everybody, it's been a while since i showed up here. glad to see the forum's alive and well. sadly, i have to post about a problem again. i have this ibook g4 (1,02 ghz model), and it's driving me nuts. i can't even be sure about what kind of problem it has. if i move the machine, the...

    powerbook duo 2300c

    well, after hours of tinkering with the keyboard, it finally seems that the wires are the real problem. sometimes the function keys work, sometimes they don't. so i'll have to cut a bit off the end of the wires, and use some sandpaper or a knife to connect the metal part to the connectors. the...

    powerbook duo 2300c

    hi, i have a feeling that the previous owner (some 10 years ago) took it apart, and wasn't a bit concerned about damaging it. the end of the wires are bent as if someone was trying to pull out the keyboard by force. the connectors, although, are in good shape, and show no damage. i'd like to...

    powerbook duo 2300c

    hm, sad news. i guess i'm not going to find another keyboard easily. btw, i have a fully functional keyboard from a powerbook 5300, i could try inserting it for pinpointing the location of the problem. do you think that's a viable option? edit: the connectors are solidly in place, or seem to...

    powerbook duo 2300c

    hi again, i was thinking of starting a new topic, but it's about the duo again, so.. i would like to ask for some assistance (again). in the past few months ive been able to get software onto the duo's hard disk (it's only 500 mb, so i'll eventually have to get another one). this involves...

    powerbook duo 2300c

    thank you. with your help i made it. :) to answer your question: previously someone suggested to take out the hd and stick it in an enclosure or mini-ide (?) to ide adapter of some kind. since that is far more easily obtainable than a scsi minidock, i'll use my g4 and that adapter to put a...

    powerbook duo 2300c

    btw, i got the modem to work and uploaded a sys 7.6 from cd and downloaded it to the duo last night. downloaded the 7.6.1 upgrade too. first i installed it, but *surprise* no ppp control panel. well, no problem, moved the new system folder from the drive root, and re-blessed the former 8.1...
