I have a powerPC 8500 that will not boot up.

I have a powerPC 8500 that will not boot up. Lights come on, drives spins up and nothing. Any ideas? It has been sitting in storage for years. I would like to get some info off it.

If you wish to do further testing to insure it is the PRAM battery at fault before ripping into the computer, there are a couple of things that always worked for me if the battery was really the problem:
1) Zap the PRAM--cold boot and immediately press and hold these four keys simultaneously:
command
option
p
r
Keep holding until you here a total of three (3) startup chimes, then let go the keys. NOTE: In some Mac models, the second and third start-up chime tone during a PRAM zap can be rather quiet. Either crank up the volume, do the zap when the room is quiet, of use headphones to be sure you are hearing teh tones.
2) See if the computer will boot from a system disk by holding c during boot. The disk can be a full retail install disk, a system restore disk supplied with the computer, or a utility disk like DiskWarrior or TechTools that allows booting. If the computer boots and you get video, you can feel confident that the only thing needed is a PRAM battery. You can do a hot boot back to the hard drive and the computer should work as long as someone doesn't unplug it again.
However, if neither of these work, that can mean something more sinister than a PRAM battery has gone walkabout.

    Reinstall OS X.
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    OR
    Reinstall Snow Leopard without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

  • I have an iPod touch that will not turn on.

    Hello forums! I have an iPod touch that will not turn on. I have tried everything I can to turn it back on, but I just cant find the right thing. I dont know if it is in need of a new digitizer, or the battery is dead, but I would really appreciate some help. It is an iPod touch 3rd generation.

    Try:                           
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - 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.
    - Try another cable
    - Try on another computer                            
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • I have a mac Book that will not open DVD's of Business Presentations.  I had my hard drive taken in to the Mac Store and had a new hard drive installed.  Since then I cannot open DVD's.  What is the application that I need, and the process. Tks

    I have a mac book that will not open up DVD's recorded with a presentation.  I install the disc in a HP / windows 7 and it works fine.  I had my hard drive replaced and since then I cannot open up DVD's.  Was there a application that did not get installed?  And if so what is the process.

    You need DVD Player. It should be in your Applications folder. If it is in there go to System Preferences>CDs & DVDs and for "When you insert a video DVD" make sure DVD Player is selected.

  • I have a G72 laptop that will not turn on! Please help

    Hello,
    I have a G72 laptop that will not turn on. The power button simply does nothing. I know that the battery is at least charging because when I plug it in, the LED indicator is white saying that it is charged. Sometimes when I take the battery out and put it back in it starts up for a split second, then a second or two later shuts off. If anyone can help it would be greatly appreciated!
    Thanks!

  • I have a iPhone 4 that will not stop resetting itself on its own this is my fourth phone and the second to have this problem

    I have a iPhone 4 that will not stop resetting itself on its own this is my fourth phone and the second to have this problem. I have AT&T so I need to post here instead of actually being held to get help on a Sunday night. this is a extremely frustrating situation as I count on this phone for business.

    Are you restoring your phone from a previous back up? If so there could be a problem within the back up. Try restoring your phone as a new device and then manualy reinstall all apps.

  • G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

    We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
    We were in the process of installing 10.4 Tiger before placing it for sale.
    The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
    It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
    Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
    On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
    We have done the following during our troubleshooting:
    - Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
    - Remove RAM 1 stick at a time and reboot
    - Replace RAM with RAM from another working Quicksilver
    - Replace Video Card with one from another working Quicksilver
    - Zap PRAM
    - Reset CUDA switch
    - Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
    - Tried booting from the Macintosh Server G4 Software Restore CD
    - Tried booting from Mac OS X Server CD
    - Tried booting from AppleCare Protection Plan CD with TechTool
    - Tried booting from Diskwarrior CD
    - Tried booting from an external FireWire drive with a disk image of Tiger OS Install
    - Tried booting with the hard drive disconnected
    The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

    Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
    The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
    I would look at the CD drive cables, etc, and see if another drive gives different results.
    You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

  • I have an Ipad 2 and have about 20 apps that will not update, How can I delete these?

    I have some apps that will not update on my IPad 2.  They say they are installing, but Installing is grey..not black, and they have been like this for several weeks.  I cannot find out how to finish the updates or delete them.  Can someone suggest a solution?  Thanks, Ann

    You can only delete them one at a time on the iPad. If you have an IMAP email account, go to your email in on the server using a web browser and select as many as you can at a time and delete them that way. That action will be reflected on the iPad. In IMAP - whatever you do on one device syncs across all devices. If you have POP email - start deleting one at a time.

  • I have song in itunes that will not load onto ipod ?

    I have a song in itunes that will not download onto ipod, nothing by song in library indicating there is a problem. Can anyone help me ?

    Does the song have a tick-in-the-box next to the song title? (You may have selected to Sync only ticked songs and videos to your iPod. This option is on the Device/Sumary pane that appears when you connect the iPod to iTunes.)
    Is the song in a format the iPod can play? (Is it the same format as other songs that do Sync to your iPod?)
    Have you looked (on the iPod) under songs as well as artists? (It may show up under songs but not under artists.)
    Try the Search facility on the iPod and see if it shows up that way.
