Apple Power Mac G4 Desktop - Answered Questions & Fixed issues

The monitor is likely busted and needs fixing.

Best thing to do would be to get the exact model information and then search the internet using the model name and the phrase 'how to replace hard drive'.

Could be your browser and/or Mac OS version. The G4s and even G5 Power PC Macs could only run operating systems up to 10.5.8. Minimum OS for running the latest versions of browsers, such as Safari and Firefox is 10.6. under the Intel chipset. Because the old browsers are slow, sites like Facebook and Google do not always support them. OS 10.5.8 is more compatible than, let's say OS 10.4.9. Check your OS by going to About This Mac under the apple logo on the left side of the screen. It will tell you what your OS is. Your choices: Upgrade your OS to 10.5.8 or take a giant leap to an Intel Mac and run OS 10.6.8 or later. Eventually your old G4 will not be able to connect to anything because of the browser issues.

Utilise app, you have to reset, should be auto, but sometimes requires manual input.

It sounds as though you may have a power supply going bad. The photo that accompanies your question is a G4 MDD. Is that the exact computer you have? If so, the power supplies are known to go bad on these specific machines. I had to replace my power supply last year. I would suggest - if your Mac is a MDD - doing a search on that topic. I found very good help at the Apple forums. If you determine the power supply is the culprit there is a gentleman in Austin, Texas who rebuilds power supplies. He sells through ebay and offers a very good and fair deal. His ebay ID is baltimora2000. That's who I got mine from and it is still running well after over a year of use. Hope this helps you out.

Here is an old Mac trick that sometimes works. Turn computer on. Hold down (at the same time) Control (Apple key) Option P and R keys. Yes, you may need more than two hands. Hold those keys until you here three or four chimes. Release and wait for the computer to start. Another trick: Hold down the Option key when starting. You should see your hard drive logo on the screen. Select it, then the arrow on the right and see if it starts. If you have a backup firewire drive (and you should) plug in that drive, start with the Option key pressed, and see if both drives show up as icons. Select the backup drive, Not plug and play, more like plug and pray, If none of these tricks work, you could have a memory issue, a power supply issue or a motherboard issue. G4s are real cheap now. $40-$60 You can always pull the hard drive and mount it in another computer. And for your own protection, back up that hard drive to a bootable external firewire drive.

There is a long article about this on the Apple support site Go to http://support.apple.com/kb/ht1939

Running Leopard on a box that old is not really the optimum thing to do. It's got 64 bit architecture and being a G4 is 32 bit, your box will not take advantage of the speed increase. As a matter of fact, and this is from experience... your machine will slow to a crawl. I wouldn't stick an OS newer than Panther on a box that old. Even Tiger slowed it down to ungodly proportions.

Look for the actual ZIP drive and just below the slot to place the disk is a very small hole. Take a paperclip and push it into the hole applying pressure. This is the disk manual release.

Hi Tom,Bad news, the old G4 Laptop does not support that protocol...You can either change the Wireless security int eh router to simple WEP or purchase a wireless PC Card that supports WPA2but then again.. investing in an old G4 Laptop???Can you simply run a cable ?

Hi Ron,Well, sounds like you have another utility or extention taking charge of your Network settings... I would delete the Ethernet preferences.. although... I would need to know more about what it might be...how do you connect to the internet? Is it a PPPoE, or Cable?

You need to clarify your question.

It is possible you have a power supply failure. My MDD was doing the same thing unless I reset the PMU. There is a tutorial here on checking the PS - D275729F-09DA-4FBB-96B3-BEEEB2C04619.html It for a MDD, but I would think it would be useful for your situation.Do you have an Intuos tablet connected? The drivers for that might be causing the problem and should be updated to the newest driver available

Hi Henry,You can replace that hard drive with any 3.5" EIDE hard drive of any capacity. Here's a link on Amazon for an 80 GB for about $30: >> Click Here <<If you want to search for other drives, use the search term: 3.5" EIDE hard driveThe most trusted brands on the market are currently Seagate and Western Digital.Hope this helps!

External drives (hard drive, DVD burner, iPod, USB drive), printer, a worn out mouse button, debris in/on the keyboard, and cats are all things that can cause your computer to refuse to sleep (or wake it shortly thereafter).  Rule out these first.  I have had the same problem in the past.  It is almost always one of these that causes the problem.

Processors are liquid cooled on G4s check and see if there is fluid in the bottom of case . if there is go see ur Apple dealer, They replaced mine.

Hi, Run System Profiler. It's in the utilities folder along with Disk Utility, Have a look at the ATA bus. Does it list both disks or just your start-up disk and the DVD-drive? If your second disk is not showing here then it may well have died. Even if it does show it may still be dead and the only way to make sure is to use a stronger tool than Disk Utility. Unfortunately you may have to buy that and it's cost is not far short of the cost of a new drive.I've known apparently dead disks come to life after a short spell in a freezer inside a sealed plastic bag. Unfortunatley they rarely stay alive for long - just long enough to copy important files!
