i havent used my emac for about 6 months, and then today i try to turn it on. I plugged it in and pressed the on button but nothing seems to happen at all, no lights, the screen doesn't turn on, no noises, nothing. how can i tell if its completly bust or if its still possible to turn on, and is there a simple way to fix it?

emac, Mac OS X (10.4.5), very old

    If it hasn't been plugged into a power mains outlet for some time, your eMac's PRAM battery is dead and won't let your eMac start.
    You'll need to replace it.
    It is located underneath the eMac protected by a secured cover.
    It is the same location as the eMac's RAM sticks
    You need to unplug the eMac, first.
    Next turn over the eMac and make sure you protect the eMac's screen with a soft towel or blanket.
    Unscrew the access cover.
    You'll have to remove the RAM to get at the battery. Replace with new battery, reinstall the RAM sticks, plug the eMac back in and push the power button and see if this fixed the issue.
    Cheapest place to get one is here.


    If this is all that is wrong with your eMac, then it should start up as normal.

    Thankyou so much, the battery has come and ive replaced it. My problem now is that i lost the RAM when i took it out to put the battery in! The computer turns on, the fan starts and the computer has a single beep, and there's a flashing light underneath the screen, while the screen remains blank. Do i have to order new RAM, or can i run the computer without it somehow? also, where would buy this RAM from?
    P.S. i have a dell from a few years ago, and i took out the RAM from that and it says on it:
    "hynix:korea 07
    512MB 1Rx8 PC2-4200U-444-12
    HYMP564U64P8-C4 AB-A 0603"

    Did you take the RAM out and misplace it, or just not reinstall it properly? See http://support.apple.com/kb/HT1319 for instructions on installing the memory. It may require a touch of firmness.

    Your eMac will not start without any RAM installed.
    And you can't just put any ole PC RAM stick in there.
    Macs and the OS are very picky about RAM.
    There are precise and different specs that apply for all Apple computers and these specifications need to be adhered to so the Mac in question operates properly.
    If you misplaced the RAM that was in your eMac, you need to find it.
    If you can't find it, you'll need to order new RAM.
    For any of us to advise further, we need to know the exact type of eMac you have.
    This info is marked inside the eMac's slot loading drive behind the cover that flops down to allow the disc tray to slide in and out. If look into the drive area, just above it should be a plate or sticker that contains the info we need in order to tell you what RAM you need to purchase and install.

    ok, on the flap it says
    "serial# VM432014QQH EMC 2006
    (bar code)
    Ethernet ID: 00 0D 93 6C7D B0
    (bar code)
    EMAC 1.25GHZ/512/80/SD/B
    im looking for the cheapest RAM really,

    I am not sure how much you are planning on using this eMac or whether your planning to sell it. Even though it's relatively old in terms of processing power, this eMac is the same speed CPU as my Mac tower.
    There's still operational left in this Mac.
    If you're interested, your eMac can take up 2 GBs of DDR style RAM.
    Also, I noted your OS X Tiger 10.4 version.
    You can update for free to OS X 10.4.11.
    If you're looking to use this eMac and get the most out of it for use.

    Here's a link to the RAM type you need.
    You need to use the DDR style for your eMac.


    You can decide from the list and prices what you want to put into your eMac.

    I am having a similar problem with a couple of differences:

    1) When I press the power button, I hear the first sound of power-up (not the beep, but the click/fan starting noise). Then nothing.

    2) My eMac was not off for any long amount of time. We have had a few power outages however. It was plugged into a surge protector, but thought it was coincidental.
