G4 (Digital Audio) won't turn on! Help?

Pretty self-explanitory, I press the power button on the front of the machine and the white power button LED comes on and then immediately fades off. No reaction from the monitor, cooling fan, logic board, or anything. I checked and there are NO loose wires inside anywhere. I don't understand why the LED comes on but nothing else.

You probably need a new internal memory battery. But first do a PMU reset. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial

  • My MacBook won't turn on HELP ME PLEASE!!!! EEK!

    I was doing math homework online and my computer just shut off.  It won't power on, no sounds, no lights, no NOTHING, and my indicator light for my charger won't turn on either..HELP please!!!!  I know the batter can't be dead because it was on the charger when it crashed
    thanks,
    Mandy

    The only other option would be to take out the battery and keep it out. Plug the magsafe back in and then try to turn it back on.

  • Computer won't turn on HELP!

    Hi,
    My computer won't turn on after a few hardware swaps I did.
    Parts :
    MSI Z77 Mpower, i5 3570k @ 4.0 Ghz, ATI HD4870, Gskill sniper low voltage 2x4gb 1600Mhz, Samsung 840 series 256gb (os), 2x ST4000DM000 (raid 1).
    So here's what I did. I shut down the computer, I disconnected every wire with caution to wait for CL_CMOS LED to turn off before pulling the cord. I then switched my ram for Gskill Ares 2x8Gb 1866Mhz (occupying DIMM slots 2 and 4, same ones as my previous ram sticks) and switched my GPU for Asus R9 280x DCUII.
    I reconnected everything, CL_CMOS LED powered on. When I pushed the power button, nothing. I pushed and pushed again but nothing happens. I noticed that CL_CMOS LED turns off after I try to push the ON button on my case. When I switch the power off, the LED remains off until it flashes briefly and turns off again.
    I've tried putting my old parts back in 1 by 1 but it won't turn on again.
    Please help!
    edit : old ram timings (CL9-9-9-24, 1.25V) new ram timings (CL10-11-10-30, 1.5V)
    edit2 : The lights on my new gpu's pcb were lit during this struggle. Power could come from the pcie adapters though.

    As in Reply #1, keep that configuration and use the switch on the mainboard over to the other BIOS chip. For some reason, it sounds like the one chip may be corrupted or maybe the PSU has become faulty. Double check the security of the 24-pin and CPU power 8-pin connections.
    Thanks for your help. I fixed the problem. I am a bit ashamed to say what was wrong but ... the 24 pin connector was loose on the psu side.
    I figured it out after 2 days of disassembling/assembling computer and testing components.
    Thanks for your help.

  • My iPhone4s is on but screen won't turn on help!!

    I don't know what happened but it just suddenly won't turn on. The phone was never turned off. I can hear all my notifications but I can't do anything with the phone! I tryied resetting it but holding the off button and the circle button and that still doesn't work! Can anybody help me?!

    Not sure what is going on but if you're hearing the alerts then it would indicate some sort of failure with the screen. I assume if the screen has failed it wouldn't matter how much you try to power it off you wouldn't be able to do so because you can't see the red slider to power it off. Have you tried plugging it up to your computer and restoring it through iTunes? I'm not sure if it would (especially if ultimately the issue is purely a screen failure) but it's something you can try. If there is an Apple store near you then you might want to stop by and let them have a look. Assuming your phone hasn't been damaged then it should still be under the manufacturer's warranty...so if it is a screen failure it should be replaced or fixed under warranty.

  • G4 Digital audio won't start up

    I've got a hold of a G4 Digital audio which won't start up. The power button lights up for a split second and then shuts down. I've noticed that the red light on the m/board does the same.
    Any pointers as to what the problem might be ?
    Many thanks,
    Tony

    Do you know if this G4 has been sitting for an extended period, unplugged from an electrical outlet? If that's the case, the internal battery is undoubtedly very weak or dead, so I'd recommend replacing it (3.6-volt ½AA lithium). Have you checked all of the critical internal components, and made sure that the connections are secure and that the memory and PCI cards are fully-seated? If left unused for an extended period, there may be oxidization in the slots, compromising the connection. I'd remove the memory and PCI/AGP cards and inspect the gold-plated contacts. If darkened, I'd gently clean them with a soft gum eraser. Be sure to blow off all rubber shavings, and then reinstall them.

  • Fixing MacBook Pro For Friend - Now Won't Turn On - HELP!

    Good Afternoon -
    When it comes to computers, I'm basically a PC guy.  I"m a network admin for a big company and work with Windows all day.  I'm an advid iPhone / iPad user too, though, and do a bit with OSX.
    Yesterday, a friend at work and I were talking about his MacBook pro.  He inquired about a few things including Windows 7 on it.  I said I'd be happy to set up BootCamp for him.  While at it, he said that he had purchased a Lion USB drive and asked if he should upgrade.  I've done thousands of Windows installs and a few OSX ones so I said I'd do it for him.
    Today, I received his MacBook Pro (Late 2008) 2.4 Intel Dual Core CPU / 2GB RAM, his software, and the Lion USB key.  I booted into OSX and copied his "profile" over the network to a SMB share.  I tried upgrading directly with Lion, but it wouldn't let me as I found out it had to be upgraded from 10.6.X - not 10.5.X.  Therefore, I decided to do a clean install. 
    I booted to the 10.7 Lion USB drive and went into Disk Utility where I erased the hard drive.  I only erased it - didn't repartition or change drive's format.  Before proceeding, I thought I'd be nice and go one step further for this guy and install new RAM into his computer.  It was 2x 2GB SO-DIMM 667MHZ RAM which I read would work with it and double his RAM to bring it to 4gb.  I installed it.
    The Problem
    I turned the computer back on with the Lion USB in and only got a white screen.  The cursor appeared, but nothing else.  I thought that since there wasn't an OS on the HDD, that it would default to the next boot device as PCs do, but it didn't.  I turned it off, then back on again - except - it didn't come back on!
    So that's where I am.  I have a friend's computer which won't turn on.
    Note:  The battery is bad I've been told and will always show only 1 light of power.  The power cord is good, though.
    Here's what I've tried so far:
    - Removed the battery / power cord for 5 minutes
    - Tried with just the power inserted (Get green light on power cord)
    - Reinserted original RAM (actually did that first and it has stayed that way during all T/S)
    - Swapped RAM into other's socket
    - Removed battery & Power - held the power button down for 10 seconds - reinserted and tried to power back on
    - Got Stressed!!!
    Any suggestions would be great - Thanks!!!

    "Any suggestions would be great - Thanks!!!"
    Have him take it to an Apple store or AASP. (Stay away from Macs. You're a PC guy).

  • My brand new MacBook pro charged last night but now won't turn on, help!

    My MacBook pro charged fully last night but now won't turn on, the green battery light is flashing but no matter how long I hold the power button it won't start. I just bought the MacBook in January.

    Well then it isn't really Brand New. Brand New kinda means you bought it yesteerday or 2-3 days ago.
    In any event youy need to take it to Apple and have them fix or replace it.
    You have a hardware problem that only Apple can fix.

  • Macbook Won't Turn On - HELP!

    Last night I went to restart my Macbook and it took forever to shut down. Once it shut down, it stayed that way and never restarted. It is fully charged (it barely ever gets unplugged). I tried unplugging it, holding down the start button, and nothing works. When I hold down the start button, I get the main white apple screen that usually comes up, but once that is done loading, the screen turns black and still sounds as if the computer is on. When I shut the lid of my Macbook the little LCD "sleep" light stays on as it usually does, and when I open the lid the light turns off but my screen stays black. My computer is a little over a year old - what could be wrong?! Please help!

  • Macbook Pro won't turn on, help please!

    My Macbook 2007-08 model (all aluminum) has the start up sound internally, the screen doesnt turn on, but the light below the trackpad will turn on, then slowly dim but remain on...any help please?

    Try:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    Resetting your Mac's PRAM and NVRAM
    Boot into Safe Mode if possible. If not then try booting from an installer DVD for your computer. If that doesn't work take it in for service.

  • Changed BIOS settings, Monitor won't turn on (Help with resetting CMOS)

    Hello,
    I have an HP Envoy 700 PC Series. Running Windows 8.
    Everything was working fine, until I changed/disabled some settings in the BIOS, an dnow the PC turns on without any display.
    I need to reset my Bios settings.
    I tried removing the CMOS battery for an hour, still the monitor doesn't turn on.
    I tried playing with the jumpers (assuming I'm doing it right)..  Any pointers?!
    Pc turns on normally without a display.  This all happened when I changed my BIOS settings.
    Any help would be great.
    Thank you

    The fact that you removed the CMOS battery usually resets the BIOS so this may not be the problem, however, the computer must be left on for up to 24 hours to permit the battery to charge itself.
    You may opt to try another monitor.
