re help duo problems bcherkas netcom com brian cherkas writes chess cats ucsc edu brian vantuyl chess writes i just got a duo and i m having some difficulties if the machine is plugged in to the wall adapter put to sleep unplugged from the wall and woken up it crashes of the time there s nothing but the original system software on the machine the battery has plenty of life i think this must be a power manager problem but i don t know what to do about it also the speaker occasionally makes a high pitched hiss the noise is irregular but seems to favor sleep and restart commands i ve had my duo for a few weeks now and suffer from both of the above problems i reinstalled my system software twice in an effort to combat the problems thinking they were system software problems initially reinstalling the system seemed to help but not anymore occasionally when i try to wake up the duo i get a solid screen of horizontal lines on the screen it freezes i also get the high pitched hiss occasionally but only at startup i ve called the apple hotline sos appl three times already and finally they agreed something is astray after my duo s screen would go dim and the hard drive spun down by itselft and put itself to sleep this problem only occured twice apple sent me a box to ship my duo to be looked at in new york but the problem now is intermittent and i can t afford to be without my duo at this time anyone out there with these same problems brian cherkas bcherkas netcom com i aol brianc compuserve netcom online communication services san jose ca yes quite a number of people it seems from discussions i ve had me included i bought my machine a couple of weeks ago as well and started to experience these problems apple australia via my dealer said that this problem has a number of potential causes faulty applications faulty third party hardware modems memory etc system software pram corruption and power manager corruption and the duo hardware itself none of the above are relevant in my case except the last two maybe no applications were running the system software was re installed i have no additional hardware i have found that clearing pram appears to help for a while at least hold down command option p and r on startup unfortunately the problem returns suggesting that pram is being corrupted by something system software bug i don t have any non issue inits in my system apparently the power manager can be reset by holding the reset and interrupt buttons while powering up apple s advice but since the duo does not have an interrupt button i m not sure what they mean in this case this may also help if someone can decipher apple s advice for me beyond this apple suggest that you should follow the technical procedures to check the hardware of this duo since so many others appear to be having the same problem it would seem to me that there has been a system software bug introduced somewhere along the line and quite recently too since it only seems to be recent duo purchasers who have this problem any more comments from others in the same boat are welcome particularly apple duo engineers cheers brucet bruce tulloch sydney australia brucet extro ucc su oz au complex problems have straight forward easy to understand wrong answers
