Please help my dead iMac!!!!

Author	Topic
maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 11 Jan 2003 : 19:59:21 sobs My iMac died today, sadly. When i go to start it up, i get an amber light, and the fan and HD both spin up. However, nothing else happens. I've tried reseating all the connections, and i've also tried plugging in an external monitor that normally works fine on it (AppleVision 1710). However, i can't get past this stage. Could the problem be a dead PRAM batt, or could it be something more serious?

SpaceBoy Full Member USA 631 Posts	Posted - 11 Jan 2003 : 21:04:13 I'm sure that we can track down the problem, but to do so, we'll all need a lot more info on your iMac and the problem: What model iMac? What config? > RAM amound, system version, upgrades, etc. What was the last thing you did when the system was running? Any more info you can provide will help a lot in fixing the problem...

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 12 Jan 2003 : 21:53:50 I have an iMac 333 (tray loading, Lime). It has 192 megs of RAM, a 40 gig HD, and Mac OS 10.1.5. Before i shut it down on Saturday night, the last thing i did was play a bit of music in iTunes...nothing that would really stress the system that badly. Oh yes, and Cory, the connections underneath the posterior were the first things i checked when it did this. I tried the PRAM battery from my LCII to no avail. Anyone got any more ideas? -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 6

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 13 Jan 2003 : 03:58:54 Holy crap. I have absolutely no idea as to what happened, but as it turns out, i'm typing this from the iMac right now. However, the date had reverted back to 1970. I set it to 2002, so tomorrow when i boot up, i'll check whether its new battery time, or whether that came from me resetting the CUDA. Either way, since this Mac is going onto 4 years old, somehow i think its new PRAM batt time. -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 6
maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 13 Jan 2003 : 17:41:20 Well, a day later, i'm back here typing this on the ol' LC475, because the iMac won't boot again. Somehow, though, i think the problem may just be a dead PRAM batt, because its about time the PRAM batt ran out, plus last night when it booted, the date had reverted back to 1970. Whether that was because of me resetting the CUDA or whether the PRAM batt really is flat i'm not sure, but either way, next time mum takes me shopping, i'll drop into Dick Smith's and get myself another PRAM batt and try it. -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 6

AnubisTTP Junior Member USA 308 Posts	Posted - 14 Jan 2003 : 04:35:08 I had a problem similar to this where my iMac (bondi Rev 2 233) would randomly not start up, and it turned out that one of the large capicitors on the power supply board had overheated. Once I replaced it, and added a few extra fans to the inside of the case, it seemed to work fine.

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 14 Jan 2003 : 17:33:26 Introducing the iMac that hates being cool!!!!!! For some reason, i have noticed that this iMac will not cold-start. The power supply electronics must be warm before she'll fire. The reason i found this is that i turned it on for about an hour yesterday afternoon, which was already quite a hot afternoon. I then turned it off for a couple of seconds, turned it back on, and it booted straight up on the first try! Still, i'd sure like to know why its doing this. I think that something is on its way out... -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 6

OSX really REALLY doesn't like early G3's. try booting into 9, shutting down for a while and then starting up again. I had a problem similar to this when installing 10 on my G3, exept I got a car crash before I even got the boot sound. mlhurgh!

bobbyuggles Starting Member 6 Posts	Posted - 16 Jan 2003 : 15:20:11 Are you getting any "beeps" when it turns on? I was helping with another person's iMac earlier in the month and chimed in on some posts going on in the MacAddict boards. This thread may interest you. http://macaddict.com/phpBB2/viewtopic.php?t=2225&highlight= The puter in question is a Dual 800, but at the end of the thread there is some info that may be of help to you. In my friend's case "the processor" (as the tech said)went bad. $300 with labor to replace. Yikes. Anyway, this is my first post to these boards... I have been lurking for a few days and I like what I read here. I don't know what constitutes liberation, but in the last year I have rescued, about 15 diff 68k Macs and a Newton 2000. Overall I have about 20+ apple computers from various form factors and hope to be in a house in the next several months so I can have the room the wife promised me to spread out a bit. Currently, we live in a very small apartment (less than 700 sq ft) and I am lucky to have the room to have my Pismo with accessories up and running. :) In any event, glad to be here!

MrLynn Junior Member USA 394 Posts	Posted - 16 Jan 2003 : 19:18:31 Sure sounds like a bad PRAM battery to me. The reason it boots up when warm is because warmth improves battery output. /Mr Lynn The dinosaurs became extinct because they didn’t have a space program. --Larry Niven
cory5412 68KMLA Comrade-in-Arms USA 4679 Posts	Posted - 16 Jan 2003 : 22:04:59 that all makes sense... except the PRAM battery... what makes a PRAM battery go bad? because my iMac, which is OLDER than ML5s, is still going on it's first PRAM battery... also...

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 17 Jan 2003 : 03:56:32 Well, i got back from Dick Smiths today with a new PRAM batt, so i opened up the iMac, left it without a PRAM batt for about half an hour, did the mother of all CUDA resets, reseated all the connections, installed the new batt, put the mobo tray back in, flipped the switch, and here i am, sitting in front of that very iMac, recalling that tale.

Gothikon Full Member Australia 537 Posts	Posted - 18 Jan 2003 : 16:07:00 Wasn't there a firmware problem with some iMacs (possibly a few other machines) prematurly draining their PRAM batteries? Could that have been the cause?
MrLynn Junior Member USA 394 Posts	Posted - 18 Jan 2003 : 20:25:38 Who knows about PRAM batteries? I have two SEs from the '80s that still start up fine, and have never had new batteries (I bought 'em used, too). Just took a IIci out of the closet where it had been sitting for four years, plugged in an external HD, and it started right up!
