I would be very cautious doing this, if you are not an Apple tech. You can damage the connector for the G5 Processors, and render the machine un-usable.

You have to remove the RAM and Processor, then remove the two power connectors that connect from the power supply to the logic board. On the bottom, underside of the chassis, there are four screws. Remove them, then you can tilt the power supply out of the bottom of the unit.

Replacement, is just the reverse.

Powermac G5 screen shaking


This sounds possibly like a power related issue. If you are using a simple power strip to plug into, consider replacing it with an Uninterruptible Power Supply (aka Battery Backup, UPS). AC power related issues can cause screen waviness or shaking. Be sure to obtain the proper capacity unit for your needs. These units are rated in Volt AMPS and come in sizes from 300VA to 1500VA in the consumer product line. APC, Belkin, Triplite, CyberPower are some popular brands. The VA capacity to choose should be considered over price alone. Buying the cheapest one vs the right capacity can result in not having a unit capable of protecting your devices plugged into it. Understand these have 2 primary functions,
1. surge-protection
2. battery backup during a power related problem
There are 2 different banks of receptacles on these units.
1. Some for surge protection AND battery backup
2. Some for surge protection ONLY
Your computer would be plugged into the surge AND battery backup receptacles. When a power related incident occurs, the unit quickly switches the devices plugged into these receptacles off of AC power to the batteries, until the power issue is resolved. The time on battery is limited based on the VA capacity mentioned earlier in this solution. So buying the largest VA capacity unit you can afford will simply give you more available time on battery before the batteries are exhausted and must be recharged. On the other hand buying the smallest VA unit could result in an immediate and unexpected shut down of the computer if a power related issue occurs and the battery backup cannot handle the devices plugged into it. NEVER use these units for battery backup of Laser Printers or other high curent devices. These can destroy the battery backup.
I hope this helps with your screen issue.

How to convert Blu-ray and DVD movies to QuickTime Player compatible format on...



bdrippermac_quicktime_20100430.jpg

Apple has detailed it clearly on its official site that QuickTime will attempt to open files with file extensions associated with audio or video formats listed as below:

Video formats:
QuickTime Movie (.mov), MPEG-4 (.mp4, .m4v), MPEG-1, 3GPP, 3GPP2, AVI, DV

Audio formats:
iTunes Audio (.m4a, .m4b, .m4p), MP3, Core Audio (.caf), AIFF, AU, SD2, WAV, SND, AMR

More than that, QuickTime can play movies using the following codecs:

Video Codecs:
MPEG-4 (Part 2), H.264, H.263, H.261, Apple ProRes, Apple Pixlet, Animation, Cinepak, Component Video, DV, DVC Pro, Graphics, Motion JPEG, Photo JPEG, Sorenson Video 2, Sorenson Video 3

Audio Codecs:
AAC (MPEG-4 Audio), HE-AAC, Apple Lossless, MP3, AMR Narrowband, MS ADPCM, QDesign Music 2, Qualcomm PureVoice (QCELP), IMA 4:1, MACE 3:1, MACE 6:1, ALaw 2:1, ULaw 2:1, 24-Bit Integer, 32-Bit Integer, 32-Bit Floating Point, 64-Bit Floating Point

Obviously, Blu-ray (.m2ts) and DVD (.vob) are out of the above mentioned range. Even though you purchase QuickTime MPEG-2 Playback Component from online Apple Store and install it on your Mac, it is still unable to play commercial DVDs (such as Hollywood movies), because they are usually encrypted with special CSS anti-piracy technology, not to mention the much more strictly protected Blu-ray movies. However, that doesn’t means you are totally banned to watch Blu-ray and DVD movies in QuickTime. Actually, an available Blu-ray and DVD ripper for Mac will definitely do you a favor to remove copy protections, and rip the movies to a Mac QuickTime Player compatible format. Go to find a step-by-step tutorial about how to convert Blu-ray and DVD movies to Mac QuickTime Player supported format.

The decryption software we recommended is Pavtube Blu-Ray DVD Ripper for Mac. It is an independent and professional utility to rip both Blu-ray discs and general DVDs to your wanted HD or SD media formats. With full Blu-ray disc support, it is able to remove copyright protections of your BD disc, no matter BD+, or AACS, even the latest MKB V17 is supported as well. See the detailed tutorial as below.

Step 1: Free download, install and launch this blue ray ripper Mac.
Once you run it, click "BD/DVD Folder" or "IFO File" to load your BD or DVD files.

bdrippermac_total_20100430.jpg

Step 2: Select H.264 Video (*.mp4) as output format for QuickTime
Follow "Common Video" > "H.264 Video (*.mp4)":
bdrippermac_format_20100430.jpg

Step 3: Click "Settings" button to adjust video and audio parameters
Notice that which parameter to select has close relationship with the hardware configurations of your computer, so before your adjustment, read the following info attentively.

To play HD video, a large amount of data must be processed by your computer. A powerful system will deliver the best playback quality.
Recommended hardware configurations for H.264 HD playback on Macintosh:

For 1280x720 (720p) video at 24-30 frames per second:
[*]1.8 GHz PowerMac G5 or 1.83 GHz Intel Core Duo or faster Macintosh computer

[*]At least 256MB of RAM
[*]64 MB or greater video card

For 1920x1080 (1080p) video at 24 frames per second:
[*]Dual 2.0 GHz PowerMac G5 or 2.0 GHz Intel Core Duo or faster Macintosh computer
[*]At least 512MB of RAM
[*]128MB or greater video card

Now you are ready to set advanced settings according to the hardware configurations of your computer. Our computer satisfies the above mentioned "1280x720 (720p) video at 24-30 frames per second", so we changed the settings as below:

bdrippermac_settings_20100430.jpg

Step 4: Click "Convert" button to start Mac Blu-ray ripping.
Once the ripping task is completed, you can click "Open" button to get the output H.264 .mp4 videos for your QuickTime Player effortlessly. Have fun.

Power mac g5 shows terrible damage in tower from leaking they swear mom board is fine but its hard to believe. are any of the other parts usable for a g3 to g5 imac or g4 powermac or emac


None of the parts are usable in any other machine.
The coolant from a liquid-cooled G5 PowerMac is toxic. If your G5 is leaking, disconnect the power cord IMMEDIATELY. Flush any skin exposed to the fluid with water for at least 15 minutes.
If you want to glove up and extract your hard drive from the machine so as to save your data, do it carefully. Other than that, my recommendation is to bag up the unit and handle it responsibly as toxic waste, using the same guidelines your area uses for antifreeze.

I have an apple mac g5 10.4 osx. the mouse has a light instead of ball and i got a warning the battery was going dead. i have bought 8 batterys and none work i bought panasonic cr2032 but no work. can you...


Thanks for contacting Fixya Support, I am glad to assist.

The issue may not be with the type of CMOS battery you are attempting to use, so much as what you are doing once you install the new CMOS battery.

You need to make sure that after you install the battery, before replacing the Air duct and closing the chassis, you press the SMU Reset button on the logic board then attempt to restart your Power Mac G5 and see if it makes a difference.

I would recommend you view the PowerMac G5 manual I have provided for you below, in order to get more a perspective on the process of replacing a battery in the PMG5.

PowerMac G5 Mac Desktop: It will not boot...


Is this a liquid cooled G5? What CPU is it? Need as much info as possible like what where you doing last time it turned on? Have you looked inside the case? Do you hear any clicking when the power cable is connected for the first time? A lot of the last G5's were liquid cooled and a lot have leaked in the past. This small leak eventually ruins the power supply and worse yet ruins the logicboard and CPUs. If you don't know if it is liquid cooled look for a warning stamp on the bottom near front by the CPU fans (inside the case). It states to shut off if liquid is viable (something to that effect). Most times the liquid cannot be seen as it drips into the power supply on the very bottom. I would take it to Apple and have them check it out.

PowerMac G5 will not boot up fully, it makes it past the chime and acts like it is going to boot then restarts. Similar to when you zap the pram. It or may not eventually boot. When it does finally boot...


Do you have your G5 hooked up to a UPS? The symptoms are consistent with drive-spin-up current load temporarily overloading a marginal/failing UPS.
