TS1587 My friend has a G4 that will NOT turn on at all.  The monitor power button will light up, but monitor won't turn on; the the computer power button lights up when pressed but won't stay on and nothing else happens.  He said it USED to at least turn

Anyway, not sure if my question was sent, so here it goes:  My friend's G4 won't power on....the power button lights up briefly when pressed, but nothing happens....and, cannot even get the montior to power on...does the same thing.   He said it used to at least turn on, but now it's doing this.   Help!!??  What should we do??

If you are able to use a multi-meter, you can test to see if the power supply is culprit. Use the Power Mac G4: Power Supply Voltage Test  (Sawtooth G4) document to aide you in the proceedure.
If not the Sawtooth, Power Mac G4 (Gigabit Ethernet): Power Supply Voltage Test.
If a Quicksilver, use the pinout of the QS PSU connector here:
http://www.xlr8yourmac.com/tips/MDDps_mods/MDD_PSMods.html#update
and a testing description here:
http://www.jcsenterprises.com/Japamacs_Page/Blog/D275729F-09DA-4FBB-96B3-BEEEB2C 04619.html
The test description is for a MDD, but the basics are the same.
If a MDD,follow my instructions in the linked articl above.
One should also try a PMU reset:
http://support.apple.com/kb/ht1939
One should also  replace the 1/2 AA PRAM battery.
Also, check that the 20, 22, 24 pin connector is properly fitted to the motherboard, and that the wires are properly inserted in the connector. There is also a 10 wire ribbon, which goes from the motherboard to the power button board. Make sure that the ribbon is firmly connected at both ends, and that there is no apparent damage to the ribbon.
If the power supply tests good in a MDD, the power switch board could be suspect.

    Hi sharkbiscuit79,
    Yes your cabinet 10 on the Crediton exchange has already been installed and linked with a FTTC DSLAM cabinet (making it able to provide FTTC fibre broadband) and has been Accepting FTTC orders since December 2013.  PCP10 (with it's DSLAM cabinet within 100meters of it) is locate on the junction of Commercial Road and the A3072.
    However by the looks of things your are just too far away to obtain a FTTC (VDSL2) connection, meaning FTTC fibre broadband is not available to you.
    Have a look at the Connecting Devon and Somerset Considerations (particularly the last paragraph) - http://www.connectingdevonandsomerset.co.uk/where-when-map-conditions/
    Your best bet is to talk to Connecting Devon and Somerset to see if there are any further plans to get a fibre based service to your area via https://www.connectingdevonandsomerset.co.uk/contact-us/ (as your area may not be inscope of any further deployment). Best give them your full address and landline number too as they can check if you are within a NGA area.

  • Hi, I can't seem to get my ipod 32gb 4th gen to sync with itunes. It's brand new, but everytime I plug it in it says can't access Itunes store and nothing else happens. I enabled my firewall to allow itunes but it still can't access it. Please help.

    Hi, I can't seem to get my ipod 32gb 4th gen to sync with itunes. It's brand new, but everytime I plug it in it says can't access Itunes store and nothing else happens. I enabled my firewall to allow itunes but it still can't access the store. Please help.

    If you look at the feed, and look at the entry 'The end to an exciting field season in Aulavik National Park' you will see the line:
    <pubDateFri, 29 Jul 2011 04:00:00 GMT</pubDate>
    You have not closed the 'pubdate' tag - there should be a '>' as the 9th character. Because the tag has been left open, it invalidates everything which follows it, and thus the entire feed. iTunes therefore cannot read it, which is why the Store has not updated. Add the '>' and republish, and all should be well.
    It's always worth checking your feed by subscribing manually, from the 'Advanced' menu, or by clicking the 'subscribe free' button on the Store page (both do the same thing) - if you can subscribe to the feed it should be OK.

  • My ipad won't start up. it's less than 1 year old.  I've tried plugging it in and pressing the start button.  the apple logo appears but then disappears and nothing else happens.

    My IPad shut down this afternoon and now it won't start up.  It's less than 1 year old.  I tried plugging it in and pressing the on/off button.  After holding the button in for several seconds, the Apple icon appears, but then disappears. 

    First, try this:
    Plug it in to the wall using an Apple charger and Apple cable for several hours.  The idea is to fully charge it.
    Then hold the home and on/off buttons together for about 10 seconds.  Hopefully the Apple logo will appear and it will start.  Do not release the buttons until you see the Apple logo.
    If it starts, great.  If not, you say your iPad is less than a year old.  If you bought it brand new from an Apple Store or Authorized Apple vendor, it is under warranty.  Take it to an Apple Store or Authorized Apple Service Center for diagnosis and repair.

  • TS2551 I photo will not respond, it comes up but the cursor spins, and nothing else happens

    Iphoto will not respond, it comes up the then the cursor spins, and then will not work.

    Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS.  So to get help you need to give as much information as you can. Basic things like :
    - What version of iPhoto.
    - What version of the Operating System.
    - Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
    - History: Is this going on long? Has anything been installed or deleted?
    - Are there error messages?
    - What steps have you tried already to solve the issue.
    - Anything unusual about your set up? Or how you use iPhoto?
    Anything else you can think of that might help someone understand the problem you have.
    Posts that consist of "iPhoto doesn't work. Help" or "iPhoto won't print" or "Suddenly I have no photos!!!!!!!!!!" mean that any helper is simply guessing. More information means you get better assistance.

  • Upgraded to 29.0.1 on XP. Print preview shows but when I hit print it just "dings" and nothing else, no print. No dialog box apprears either.

    Printing from all other programs works fine including Chrome and Explorer. Ever since my Foxfire browser was updated to 29.0.1 I have not been able to print webpages.
    When I hit print the computer does an audible "ding" and nothing happens. Doesn't matter if I choose File>print, f10, <ctrl> P or "print" from print preview, same thing happens.
    The printer is on-line and recognizable by other apps.
    No dialog box appears so I cannot choose a printer.
    When I hit page setup I only get "format & options" and "margins & header/footer".
    Help!

    Hi,
    Thank you for your question. There are two things I would try. It is possible that the printer settings may need to be reset. [[Fix printing problems in Firefox]] or you Java may need to be updated. Check if they are up to date with [http://www.mozilla.org/en-US/plugincheck/ Plug in check]

  • Macbook White Screen (and nothing else happens after that)

    Hi All,
    I have a problem with my wife's macbook (which is exactly 13 months old, Aargh!)
    She was having some problem with slow apps etc, so decided to restart, the restart didnt go through so she tried holding down the power button to force shut down.
    When she tried to restart it several seconds later, it chimes but it gets stuck on a white/grey screen with nothing on it, not even the Apple logo. Something started whirring louder and louder for the first 2 minutes and it stayed that way for at least 10 minutes++. Note that it shuts off immediately as soon as I push the power button down.
    I have tried all the startup key combinations listed on http://support.apple.com/kb/HT1533?viewlocale=en_US
    But other than the Firewire logo showing up when I pressed T down at startup nothing else works, the actual Firewire target disk function didnt work when hooked up to another mac.
    I have also tried taking off the battery/AC adapter and holding down the power button method to no avail.
    The Macbook itself was bought in the US, but we are now in Europe so the startup CDs are not around, or at least not yet . I doubt it will do miracles anyway...
    I know I'd probably have to take it in to an Apple Store to see whats up, but I thought I'd share it here first.
    Let me know if anyone have similar experiences..
    Cheers.

    Try resetting the PRAM by restarting your computer while simultaneously holding down the Command-Option-P-R keys until the computer restarts a second time.
    Hope this helps

  • I've just downloaded itunes 12 and when I connect my IPod classic 160gb, I tunes shows it'sP name briefly and then then ipod silhouette at the top left simply greys out and nothing else happens. Please advise.

    I've just downloaded itunes 12 onto my pc. When I connect my IPod classic 160gb, it's name shows up briefly before the ipod silhouette at the top left simply greys out and nothing happens.
    Please advise.

    I finally resolved my problem after spending way too much time on it. I simply handed my 160GB iPod to my husband to put his fav Stones & Beatles songs on and I went back to my 80GB Microsoft Zune which has never disappointed me.
    After spending so much time trying to figure this out I did finally take it back to Apple Store who performed a diagnostic and found there was a problem with the device. They replaced it with a refurbished one which has similar issues. All I wanted to do was listen to my music. Was that too much to ask? So I am happy to be free of this problematic device. No more Apple for me!!

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
