G3 won't power up at all

I'm running 9.2 on a B/W G3 and was working fine, but I moved it (from one side of desk to other. It worked fine. But I didn't like the arrangement, so I moved it back (powering down, unplugging cables/cords, moving, replugging) and now it won't power up (either from the power key on the ADB keyboard or the "oi" button on the front of the Mac.
I tried 2 different ADB keyboards and 1 USB keyboard and nothing.
Any thoughts? Seems funny it worked 1 minute and 5 minutes later wouldn't.
Thanks!

Hi, Michael -
Welcome to Apple's Discussions.
First thing to do is to recheck the power cables/cords. Be sure the one for the Mac is secure at both ends. If you use a power strip or equivalent, make sure it was not turned off accidentally.
If that doesn't fix it, then try a CUDA reset -
Article #95065 - G4 (PCI) - Resetting Cuda
That article describes a G4 (PCI) model, but the procedure is identical for the B&W G3.
If that does not fix it, try replacing the internal battery. Many Mac models, particularly G3 machines, will refuse to boot if that battery is too weak or dead.

  • IPhone 3GS, won't power on at all.

    Hi,
    earlier today, when I plugged my phone in to charge, it started with the usual symbol for charging, from a flat battery, then after having to step away for a short while, I pressed the on button and a white screen would appear, no icons etc.
    I tried to do a restore, but with ios4 now out it insisted on that being installed, and it failed, there was an error message with a code, but it came and went to quickly, and now it won't power on at all.
    Any ideas.

    Good news, after searching the support section, and finding these http://www.apple.com/support/iphone/assistant/phone/#section_2 instructions about restarting, that got it back to the normal screen.
    I wasn't planning to update the software straight away, but since I've got it now...

  • IBook G3 700Mhz won't power on at all

    Hello,
    My iBook G3 700Mhz (CD-ROM, 2002 model) recently died completely - it won't power on, there is no chime, no disk activity whatsoever. There were no indications that there was a fault prior to this - I had used it with no problems just a few hours beforehand. I have heard of logic board failures, but from what I have read some form of activity still occurs, or there are faults that occur sporadically shortly before it completely fails. My iBook has run perfectly since I bought it in 2003 with no sign of any problems at all.
    Is this likely to be a logic board fault? Or could it be a fault with the PSU? The battery still holds a charge (it is on 2 lights), the power cable still turns orange when plugged in, so power is still getting to the machine.
    I appreciate any help anyone can give - I would like to be able to get to the data on my hard drive, as although I have made regular backups, the last piece of work I was doing (the day my book died) will still be there, and hasn't been backed-up.
    Thanks,
    Andrew
    (iBook spec: G3 700Mhz "P72B", CD-ROM drive, 640Mb RAM, Airport, OSX 10.4.10)

    Thank you very much for your help, very much appreciated. Unfortunately, I have no friends with iBooks (just MacBook Pros - very flash), but I have ordered an ibook G4 which, should it eventually arrive (I managed to be sent a job lot of laptop hard disks by accident today, which was akin to rubbing salt in my wounds) I will use to test the power cord.
    I think the power problem sounds the most likely candidate, thanks to the article link you sent me. One thing I noticed last night when trying out your tips was that when the power lead was connected, the battery life indicator stayed on the whole time. I'm not sure I remember it doing that before, so that could be an indication of the problem. Also, the ring on the power cord stayed orange throughout, despite the battery showing full power. There are no Apple Stores where I live, but I am hopefully visiting a city with one this Weekend, so I may well take my iBook with me for diagnosis. I'm not sure I can justify the price of a logic board repair, but a PSU replacement might be more palatable.
    Again, thanks very much S.U. and Ronda. I will keep you posted on any further developments.

  • Thunderbolt display won't power up at all

    Hi I recently purchased a new 2.5ghz i5 mac mini and a thunderbolt display and when i plugged it all in the display wont power up all. Tried the hdmi connection on my hdtv and it worked fine. Tried a display port to hdmi adapter in the thunderbolt port to my hdtv and that worked fine. updated the mini to the latest software, checked all the cables, reset the pram still can't get it to power up. Am i missing something? There is no power button on the display that i can see, from what i understand it is supposed to come on when the mac powers up. For all the people that own a working thunderbolt display when going does it make any kind of noise or anything that you can tell that it is going, apart from a picture being on the screen. Because mine is seems to be dead doesnt make a sound, screen is blank. So far its a worthless piece of junk & i'm 3hrs away from the nearest apple store to get a replacement or get it fixed. Really starting to wonder about purchasing anything apple, just have one problem after another, first it was the apple wireless keyboard not pairing with lion os now this. Any help appreciated

    I suppose the TB cable could have gone bad.  If you get a another TB cable and plug it in from your MBP to the TB port of the display and see what happens.  If it powers up and all ports work then it means the built in cable is bad.  If nothing happens means the TBD is dead and will require repair.

  • IMac won't power up at all

    Have an iMac 266 G3 "Strawberry" tray load with Panther. The other day it would not power up. No chimes, no lights. Completely dead. Swapped out the power cord and also plugged it into several different outlets but nothing. Same results with the keyboard power button. The machine hadn't been on for several weeks prior to the problem.
    A while back it did give an error message when booting up about the time and date being incorrect. Is that a battery issue? Could a dead battery prevent the machine from powering up at all? Remember, no chimes, no lights, no nothing. I don't want to spend a fortune on repair. Can I fix this myself or am I outta luck?

    The battery may not be your only problem if your system info is correct:
    "G3 iMac "Strawberry"; Mac OS X (10.3.2); Tray load, 266 Mhz, 96 MB RAM"
    The minimal RAM requirment for OS X is 128mb. Suggest you purchase as much as you can afford while you are battery shopping.

  • Power mac g4 Model 8570 won't power on

    A few months ago I installed Leopard on my g4 tower and since then I've been having power problems. I realized I pulled the wrong power cord in when I set everything back up, so I figured that waws the problem, thinking it was an issue of not drawing enough power; however, the problem has persisted. It used to be that I'd have to press the power button a couple of times for it to really take, then it was taking longer and longer to make that happen. Now it just won't power on at all. We popped the battery out for a bit, unplugged everything, and then re-assembled it but that didn't work. I keep reading about a pmu button or something, but I don't see anything like that and none of the diagrams on here match my logic board. can any one suggest what I can try? does my model even have a pmu button? I'm not that seasoned at trouble-shooting the hardware so any suggestions would be welcome.

    Thanks so much, this was incredibly helpful! Unfortunately it didn't fix the problem tho. Is there anything else you would suggest I try before replacing the battery? I want to try all options before having to buy a new battery, and also whatever I can do before having to take it in somewhere (not having a car makes that a difficult task). Thanks again!

  • Power mac G5 2004 won't power on

    Hello all,
    my Power mac G5 June 2004, won't power on at all. I've changed the logic board, power supply, dual processors, front panel board, and front panel board cable. Still getting the same results. The only thing I could think of next is the power button.
    Please help!!!

    No more wise guy stuff then.
    If you have tried and thus eliminated everything else, then perhaps it is indeed the power button.
    However, are you perfectly certain that it can be nothing else? Were all of the parts that you used for troubleshooting purposes from some other Mac or from some kit or did you purchase them or what?
    Sometimes it can be more than one thing. And at different times. I am not sure exactly what the minimum configuration for a boot-up is but perhaps search for that and see what pops up. Reduce it to that and try it.
    If you have a working Mac from which these replacement parts are coming it is not high on my list of favorite strategies but you can try plugging the suspect components into the working Mac one at a time until you find the culprit.
    Are there any parts that you replace that require you to press the SMU reset although you have done it once? Perhaps a call to Apple or again search on that for suggestions.

  • Dv7-1273cl won't power-on

    Warranty still good until 2011-03-31, bought at Costco. I press the power button and the lights come on for about 1-2 seconds and then it dies. Tried taking the battery out and putting back in, no luck. Won't power-on at all w/o the battery in (no lights, no nothing.)

    to those who have NOT solved this issue yet, we know you are out of warranty, so try this. i'm not sure how long this will last, but this should help. the computer's power circuit has a defect that HP didn't mention. the dv7 2nd Gen. has a problem where the primary power circuit stops responding to the correct voltage. here's a quick fix.

    short the center pin to the outside white wire using solder to bridge the connection between the +14.4V connection coming from the charger. i personally used 26AWG wire and carefully wrapped it around the 2 pins and then soldered them. thin solder braid also works very well. i must reiterate that you cannot use ANY other pins than the second to the left. review this video on youtube for reference. this is what helped me to get it running.
    http://www.youtube.com/watch?v=In5JoDVlZ0Y
    try to use the wire with the solder as its a better connection and is more solid. do not use rosin core solder, only tin-lead solder. you may use fluxall tin-lead solder to make it easy, but its a tad messy at first when heated. flux kind of spits at you a little bit. haha.

  • Palm Z22 won't power up

    My Palm Z22 will not power up.  It was working yesterday morning and just shut off while at my desk.  I thought it might be the battery so I plugged it in to charge it, but it still won't power up at all.  Is there some sort of reset button?
    Post relates to: Palm Z22

    Look at the back of the device for the tiny hole marked "Reset"... Press gently with a paperclip, etc. and release.

  • Help! Macbook Pro won't power up!

    Hi, I have a new 2011 MBP 15" (1.5 months old).
    When its up and running it works fine, and I'm able to shut down and restart it normally. As soon as I leave it off for more than a few hours (usually this happens overnight when I shut down the computer before going to bed)
    The next morning the computer won't power up at all. When I press the power button I can hear something whirring/spinning and then 3-5 secs later the power just cuts off. The screen doesn't even light up, I don't get to hear the apple chime at all. Repeated attempts to power up the system get this same result.
    I suspected it was due to cold weather (winter in Perth now). I find that every cold morning if i warmed up my macbook placing it near the heater, it will be able to boot normally after it has warmed up. But if ever the machine gets a chance to cool down, it goes into a coma? This happens when I put the mac to sleep and am away from it for more than an hour, it won't wake up!
    This is so dissapointing to come from a product that comes at such a premium price. I hope I can get some help on this! It's really really frustrating.
    I am reset the PRAM and SMC several times and they dont seem to do the trick. I ran the apple hardware tests, even in extended mode and they all detect no problems. Hellpppp

    How cold is cold where your MBP is? In any case take it to an Apple store or AASP. If none availanle call AppleCare.
