Q: Stumbled across a G5.. new to Apple PC's... Boots, then shuts off. (Large Images)

My friend gave me his huge hefty Apple iMac G5 (I believe) as he said it didn't work anymore. Being rich and stubborn he went out and bought something else and said I could play with this as I am his "techie" friend. I plugged it in when I got back home and it gives me the White Apple Bootup Screen but then Shuts itself off... like a security measure. I am not sure if there is anyway to enter a diagnostic mode by hitting F10 or a similar key on the USB keyboard I plugged into the back of the system.

 

I counted 8GB of PC3200 RAM which s quite a lot, so I'd imagine this thing must've had some power when it worked. I am just curious to why it is not booting up. I do not know anything about Apple computers, I have only worked on small devices like iPads and iPad touches, etc...I have a feeling I will most likely be salvaging a lot of components that are still useful from this system but if I could get it running stable I'd be extremely happy.

 

I have never seen a fan that goes over the RAM that sits behind whatever is behind the G5 casing, I'd imagine either the CPU/Heatsink is underneath that section or the Power Supply, or both. I am not familiar with how Apple builds their computers. I am unsure of what a "Class 1 Laser Product" is as it appears to be the CD/DVD rom to me. My friend didn't state what he did with this system when he had it, I know he didn't game but would probably rather do work on it, I honestly have no idea and don't feel the need to ask.

 

I will post a few pictures of the system and if anyone can help or suggest anything it would be greatly appreciated. I wish there was someway to enter a diagnostic or Bios when booting it up to possibly edit or run some type of tests but I do not know if that is possible. Thanks, and I apologize if I posted in the wrong section of the board.

I took out 4GB of RAM just to see what type it was and it matched... it has been re-inserted.

    Okay well I read somewhere holding ALT will get you into some type of bootup menu and yes it did, and this is what I saw.... if I click the Reboot looking icon it just shows me a timewatch then the same screen, if I click the Drive in the middle it goes to the White bootup screen then shuts off. The same goes for if i hit the Next button, bootup screen, then powers off.... it seems like maybe I am dealing with a bad Hard Drive?

    This is the only hard drive I found in the unit, it appears to have SATA so I hooked it into my external drive reader

    I tried connecting through SATA and nothing. I could hear the drive humm but nothing would be read or recognized onto my PC. Maybe it's a Mac for Mac thing only... Maybe I just have a bad or corrupt drive, which I am hoping as all the other components would still be in tact.

    Hello,

     

    There were a few generations of G5s.

     

    If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...

     

    http://www.chipmunk.nl/klantenservice/applemodel.html

     

    http://www.appleserialnumberinfo.com/Desktop/index.php

     

    How to find the serial number of your Apple hardware product...

     

    http://support.apple.com/kb/HT1349

     

    Yes, you could only read the drive on a PC with something like MacDrive.

     

    Actually it looks hopeful from your screen shots!

     

    Tough without the Tiger Disk problems, but try fsck...

     

    To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:

     

    1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup.

    Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.

     

    2. At the command-line prompt, type /sbin/fsck -fy

     

    (SPACE between fsck AND -fy important)

     

    3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:

    The volume (name_of_volume) appears to be OK

    If fsck found issues and has altered, repaired, or fixed anything, it will display this message:

    ***** FILE SYSTEM WAS MODIFIED *****

     

    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).

     

    4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

    Thanks, I did see the SN listed and know where the info is in regards to that and did not want to post it publicly. As it is very late here and I want to get up to watch Team USA versus Russia in the Olympics I will have to continue my research and work tomorrow and figure out exactly what I have.

     

    I am very unfamiliar with Macs... Sorry to say to all you Apple lovers I have always been a PC Geek

    I am willing to learn though which is the best way to conquer anything and build upon my resume of knowledge. So I do not have a "Mac" Keyboard, I am using a simple Logitech USB keyboard and am not familiar with the "CMD" key would be designated as. I was given solely the tower to work with (like I am some kind of magician). As to get to any command prompts I have no idea and will have to read up on procedures. This system would be very cool to get working again and I can probably keep it if so. The case is so heavy and sturdy I love it and wouldn't mind modifying it to put my current PC into it one day if possible.

     

    I apologize it is late but I will get on it tomorrow morning to try and figure out a little bit more about this system and what I can do to resolve the issues... thank you so much for your input and your hopefull advise.

    SInce you booted up in the startup manager ok, it's likely to be a bad hd or corrupted OS.

     

    Do you have the installation dvd's?  See if he can give them to you.

     

    Restore Tiger 10.4 & Leopard 10.5  DVDs are available from Apple by calling  1(800) 275-2273. Have your serial number ready. Have your credit card ready too.  There may be a small fee.

    Well I think I am able to get one of the CD's/DVD's I am not sure which one later today or tomorrow. However ever since I put the hard drive back in and tried to power up the system I am getting nothing. Just the red lights and fans spinning. I've made sure I've connected everything back together properly several times, I am thinking the hard drive just died out. Now if I wanted to replace the hard drive can I pretty much buy any 3.5 inch SATA drive or does it have to be MAC certified or something? I am quite upset I thought I was so close to getting this puppy purring again, but what can ya do... this was just a gift that was going to be in the garbage if I didn't take it. The case was very appealing to me and if I cannot get the system running I will be modifying the case to put my PC into it as I love the sturdyness and the handles uptop.

    I should boot up in startup manager.

     

    See what happens when you take out the hd.  There are some rests. There is a poweron reset.

     

    The startup manager will list all of your bootable partitions then give you a choice of which to boot.  Hold down the option key ( or alt key on a pc keyboard ) then power on. Continue holding down the option key until you see the startup manager. This brings up the startup manager. Click on your hd or disc. Click on right arrow key.

     

    It's the speed of the sata bus.  1.5 gig I believe for all g5's.

     

    Some hd's have jumpers to slow down the speed.

    Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.

     

    Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

     

    reset-nvram

    set-defaults

    reset-all

     

    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

    Should the fail...

    Try taking the battery out for 10 minutes.  Put battery back in.  Cross fingers. Power the machine back on.

    As mentioned by rccharles, make sure the SATA drive is 1.5 Gb/s compatible, not all are.

     

    One other problem with these is that the thermal paste may need replacing, the other is the lead-free Solder issue...

     

    If you're sure the RAM is good, try the Hair Dryer trick...

    Thanks, seems like lots of info. I am just curious to how I managed to get the Apple sound and Load screen to stop showing? I have checked almost every connection imaginable, I have had trouble finding the "CMOS" battery or whatever is similar for Mac's, I think it was mentioned to be near the RAM. I've tried booting with no HD connected as well as it connected, even to the other jumpers.. and nothing. I may be in over my head with this thing but I will continue reading

    It's a bit of a mystery as to why those stopped, but I suspect whatever problem it has is getting worse.

     

    Oh, I forget, did we try removing all power & periphers for a few hours, then hook up & try booting again? (Thing maybe a bad Capacitor in the PSU).
