PowerPC :: No Airport Card Installed After Power Supply Replacement
Nov 11, 2008
I just picked up my iMac g5 20" (2.0 GHz PPC) from the Apple Store for having the power supply replaced. Now I've lost all traces of the built-in Airport Extreme Card: When I click on the now hollow diamond-shaped Airport icon, I get a grayed-out prompt stating "No Airport card installed". Any record of an Airport Card under System Profile comes up with "No information found". My Airport Express does not show up in Network settings either.
Airport Express works fine in my Macbook Pro, so I know it's not something wrong with my Airport Express. I tried installing the "Login & Keychain Update", but can't: "You cannot install Login & Keychain Update on this volume. This volume does not meet the requirements for this update". Ran Disk Utility and came up with errors and unable to repair disk. The iMac was fine going in - except, of course, for the random shut-downs from a failing power supply.

I have a MDD quicksilver with a bad power supply. I have done some research and have found that the MDD psu does fail more than most. One of the biggest problem is cost. As most of you know replacements run $125 and up What I would like to know is has any one found out what actually goes wrong in these psu's? With the amount that have failed I would guess it is a few components that are commonly going bad on each unit. If I cant figure out whats wrong with the unit, maybe a replacement? I have seen the standard atx power supply mod for the mdd but I was thinking something along the lines of the same form factor as the factory psu. the guts could fit in the factory psu enclosure with rewired new 24pin plug. Again I am just throwing this out there maybe some one all ready did this.

I have a PowerMac G5 with the first motherboard that is out of order, and another PowerMac
G5 Late 2005
with 2x2.0GHZ
Mounting the powersupply from the 2004 on the 2005 is the powersuply compatible or not?
EDIT: I looked on Mactracker and compared the two:
Max Watts in the first is 604W and 450W on the late 2005.
I want to put a powersuply from a G5 2004 (604W ) on a G5 2005 that had a 450W powersuply is this possible ?

I need to replace the power supply in my Mac Pro (2008) but I'm stuck at getting the small cover off. I've removed the metal plate that was under the optical drives (POV when looking through the side).
But it seems there's a small cover for the power supply that's similar to the big processor cover for the liquid cooled G5 towers. I can't figure out how to remove that.
Does anyone have a link to a manual or take-apart guide for the Mac Pro?

I'm just wondering if anybody knows whether it is possible to obtain a replacement battery and power supply for such an old computer. My 17-inch MacBook Pro is about five years old, and the battery seems to be completely dead. It will not start up, will not take a charge, and cannot be used, whether plugged in or not. A multitester test suggests that the power supply no longer works either. My MacBook has one of the older-design power supplies, with the circular port, rather than the newer, magnetic, rectangular ones. I'm planning on getting a new MacBook in the near future, but I need to access some things that are saved on my old Mac's hard drive, if at all possible.

I could purchase another power supply for my Apple TV? I managed to lose it during my last move.

June 5th to September 19th.....not too bad, considering the laptop has been on the road quite a bit.
I finally lost (seems so, at least ) that little semi-clear plastic cap shaped like a rectangle with rounded edges that covers/protects the connector of the MBP power supply when it's not connected to the computer (and being transported).....at least, that's what I used it for.
I did a quick search and couldn't find any relevant posts, so sorry in advance if this has been addressed.
Does Apple or someone else sell a replacement for such a dinky little thing.....although, frankly, I found it to be quite useful to protect the connector .

I have an Airport card installed in my Cube. Whenever I turn it on it says "none of your trusted networks can be found. would you like to join the network named default?" default being the name of the network in our house. none of my other computers do this, they all join automatically. how can I fix this?

I hav" a "late 2004" G5 2.0 dual processor. To upgrade graphics card, I find many require a power supply splitter. Do I have a molex 4-pin connector? I can't see the location inside the box.
Information:
G5 dual 2.0, 2.5Gb
Mac OS X (10.4.3)

I am trying to switch out mobos. I want to put a desktop mobo in a minitower case. But my understanding there is a jumper that can be changed to switch between the models. Has something to do with the power supply differences if I remember correctly. Anyone know where on the motherboard that would be located? in need to find it because currently using the desktop mobo in the minitower case it will not power on at all.

So, I have the latest 2.5 G5 quad.
The power supply recently blew on it so I had the local Apple shop replace it. I brought her back home and powered her up for the first time and the fans are on full blast the whole time.
Usually the fans would be on high during start up and while shutting down...but they would ALWAYS slow down when OS X is loaded. Now they are on high all the time.
specs: 2.5 quad, 6.5 gb RAM, 2x 500gb HDD's, GeForce 7800GT, 10.5.6 (I know 10.5.7 is out...I'm installing it tonight, as it took over an hour to install on my iMac's)
I know I can just take it back to the tech, but if I can fix it with a simple setting then I'd like to try that first.

Have a Power Mac G4 MDD - Apple genius bar looked at it and told me probably need a new power supply (shutting down at will and having trouble powering up but before that the computer was running well) and I'm not sure if I should get a used or new one on ebay or if you have a better idea. Can't afford a whole new system so want to resurrect this one.

I have a first gen imac g5 (bought it in dec. 2004). So far I've had three major problems with it:
1. After 6 months of use, the power supply burned out and had to be replaced.
2. 3 months later the well known video problems due to faulty capacitors appeared. The midplane board was replaced.
3. I was out of the country for 6 months; after the midplane board was replaced in August my imac was sitting unused. Booted it up yesterday and the computer would just hang. Took it to the genius bar at the apple store today and was told the logic board has to be replaced. Luckily, though the computer is out of warranty, Apple has extended the warranty for this specific problem.
At this point, I am very frustrated. I am going to call Apple and request that they replace my imac with a new one. It is obvious reading the posts here and Apple's boards (btw, before Apple's board monitors started censoring and delting posts that address these problems - my post on the Apple board yesterday was deleted by the monitors) that many users have had lemons with the first gen imac g5. I consider three major problems in less than a year to be symptomatic of a "lemon". If Apple doesn't replace lemon imac g5's what are the alternatives...I wonder if they would buckle if enough people threaten a class action lawsuit. Something must be done to alert the general public about this problem.

Recently I didn't do my research, and I purchased a Quicksilver power supply to put on a Gigabit machine. I noticed it had four extra pins which look like some of the ones they use to power processors in some PCs (tho I've come to find this is for the ADC port). I dug a little deeper (Googled "powermac_g4.pdf") and found out that some of the pins have differences between the Gigabit PS and the Quicksilver PS.
Has anyone else had an experience like this? Will the PS work without any wirecutting or do I need to get a new one?

After reading about Psystar and all that crap I have become inspired. I want to build my own hackintosh . I have an old G4 Gigabit Ethernet PowerMac that I aquired a few weeks back. I was wondering if it would be possible to gut it and use the case for my new hackintosh. Will a standard mobo fit in it? Can I easily replace the powersupply?

I recently fired up a old MDD G4 at work, and after 5 seconds or so, the APC unit that it was connected to started warning that there was a current overload, and killed the power port. I plugged in another computer to make sure that it wasn't a general overload, and it ran fine, so it's a problem with the MDD. The power supply area smelled a little different, and it was hot. The system powers on completely (fans, hard drive, etc.), but it just trips the overload circuit by drawing too much power. Is there a way to take apart the PSU and see what's going on?

I've been lurking for the last 12 months but haven't posted until now. Does anyone know if it's possible to purchase a new PCB and lead for the power input. My youngest kid pulled my mac off the sofa and it landed right on the input which knackered up the lead forcing me to buy a cheap chinese job. I've taken the cover off and pulled out the small PCB to inspect it and it did have a cracked solder. I fixed that but the connection is still very fussy, I can't move the mac much or it will switch off (dead battery too). While I'd love to go out and buy a brand new macbook I simply can't afford it right now so patching up this one is my only choice. It needs ram, new battery, proper lead and power supply PCB. All easy to find except the PCB.

My 2*1.8Mhz G5 tower (second version) shutdown two day ago and refuses to turn up again. I have absolutely no sign of life, not even the external white led or the internal red one. I'm trying to figure out whether it is the power supply of the start button which cause the problem.
Is it possible to test a G5 power supply like an ATX power supply, by connecting two pins which would make the fans start ?

I've recently got a refurbished Mac Pro from Apple, and once I'd set my system up and tried to connect to the internet, I soon learnt that there was no Airport Card installed, so I'm unable to get a wireless internet connection.
Having looked in the Apple Store online, I can't see any internal cards, just base stations. I looked up the Airport Extreme Card, which I thought would solve my problem, but from what I could see that is only compatible with older Macs.

i have a late 2007 macbook which came with pre-installed airport software. it was all fine and dandy up until this week when i got ethernet for my modem so my computer was connecting to the internet that way. i turned off the airport since there was no need and i have no service in the area.
however, around this time the ethernet cable was jammed and i had to tug really hard for about five minutes to dislodge it from the computer. the connection works just fine so that's not the issue.
i tried to turn back on the airport but it wouldn't. so i rebooted, installed all the updates from mac and then the options, even from the system preferences menu, said that there was no airport card installed.
what could be the issue? could the card have been dislodged? would i have to reseat it or did the updates mess with something?

I have a 2010 Intel Mac Mini. The mini has worked great for a solid year plus on wifi, one day i decided to relocate my wireless router and it all went downhill from there. Wireless has worked intermittently since and now says "No Airport Card Installed" I tried it via ethernet as well and it says "Cable unplugged".  All other wireless devices work great (Ipad2, Macbook, Ipod Touch). I have reset the SMC and the NVRAM 3 times to no avail

Last night I watched Netflix just fine, put my laptop to bed and this morning, no wif-fi connection!!. Blank airport icon reading "No Airport Card Installed." Recently installed new battery, not that that probably matters.Do you think my Airport Card died overnight? I have tried restarting twice and nothing. Other devices can connect to the wi-fi just fine.Staying tethered to the modem is a drag especially since I just forked over $130 for a new battery! I have a MBp-17 with OS 10.5.8, Mahalo from Kona Hawaii.
