Moderator: charlieman en http://www.applefritter.com/node/23763 I have a 466 firewire iBook with an original airport card installed and 10.3.9. Airport worked fine and connected to my network. Gave the iBook to my niece. They added a wireless network at their house (not sure what brand, not Apple) and she could not get the iBook to see or connect. After trying to troubleshoot over the phone without success, I had her send it back. Hardware test says the airport card is fine, I can turn it on and off but it does not see or connect to my network. I can create a network on the iBook but none of my other computers can see it. I've tried re-seating the card and the antennae connecter without success. I don't have another original airport card to swap. Any suggestions? Thanks! Sun, 30 Nov 2008 08:32:38 -0800 http://www.applefritter.com/node/23751 Hi - I have a 20" aluminium cinema screen, and the pins on the DC plug (the one that goes in to the PSU) have become damaged in transit. I attempted to bend them back into shape as best I could but I am getting no power from the screen. I found out that Apple don't actually repair this - they simply provide a replacement screen at something like 80% of the cost of a new unit. For one broken plug. And I can't get hold of a spare plug to even attempt to resolder myself (typically this is an Apple proprietary item). So the only solution I can see would be to put a new male/female on the plug/PSU socket. Or wire directly into the PSU. But of course it doesn't look easy getting into the case of the PSU - no screws on it. So if anyone has any ideas, I'm all ears! Otherwise I now have a very expensive aluminium paperweight..... Thanks!

Ben Sat, 15 Nov 2008 01:14:25 -0800 http://www.applefritter.com/node/23686 Sorry if this is a silly question, but an Apple //c I recently purchased doesn't seem to boot up. It starts the drive and beeps, but there isn't any video on the screen. (The screen is connected via RF, and I've tried toggling 80/40 columns) If it helps, I'm running it on a 12v power supply. (I think the original one was 15v...) Is this machine broken, or is it human error? ;) Fri, 14 Nov 2008 15:04:30 -0800 http://www.applefritter.com/node/23651 I have a 20" Intel Core Duo iMac that only intermittently powers on. Sometimes if I plug in the power it will instantly start and work fine so long as you don't reboot it (it won't start back up). Other times it won't turn on, even if I push the power button, but after 5-10 minutes it will randomly turn on and again seem to work fine unless you reboot it. I believe it is probably the power supply, but it doesn't look or smell like anything got fried on it. The part number on the PSU is 614-0378 (identical to [url=http://cgi.ebay.com/Power-Supply-for-Apple-iMac-17-G5-iSight-Intel-661-3780_W0QQitemZ360101726034QQihZ023QQcategoryZ51044QQssPageNameZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting]this one[/url]) . When I plug it in and it won't turn on there are no diagnostic lights lit up. I also checked out the power with my multimeter on the 5-pronged connector on the PSU: the two black wires were grounds, the grey ones were giving out ~12V (it fluctuated quite a bit between 11.5 and 12.5), but I couldn't get any reading off of the brown one. Does anyone know of a way to properly test the PSU? Does it sound like that is the problem or could it be something else? BTW, I already replaced the NVRAM/PRAM battery. Thanks!

Sun, 12 Oct 2008 06:18:21 -0700 http://www.applefritter.com/node/23524 Hello, My G4 Quicksilver keeps popping up a Kernel Panic everytime I try to install an OS or run something off CD. I had to format it because it was giving me problems (last resort) but that didn't work at all. Here's what happens. I turn on the computer and anytime I put in a non-bootable cd in the drive(like the OS install cd for example) it causes a kernel panic. Only bootable cds like apples hardware test will run. I ran that in both standard and extended mode but it detected no problems. I have tried many of things recommended in books and by apple themselves but no luck. These include Different hard drives, taking out all extra hardware that didn't originally come with the machine PMU reset Apple Hardware Test (to check the memory) as well as some other things. I contacted Mac Professionals and they said to replace the logic board (if it is the problem) would be $500, which I don't have that kind of money for a repair. So basically I have a G4 with no OS on it and continues to give a kernel panic anytime a non-bootable cd is inserted. On the rare instances that it does try to install my OS (10.3 Panther) the screen displays blocky colorful artifacts before freezing completely or telling me to restart. Here is the kernel panic error (part of it) I don't have the rest because I can't export a log as I have no OS. "Unresolved Kernel Trap (CPU1) 0x200" I can't find any information on fixing this anywhere. So I am asking on forums in hope someone can help me. Please don't recommend disk utility or any other software that is not bootable off a cd. Since I have no OS, I can't use any of that. This is truly a hardware issue.

Thanks Wed, 01 Oct 2008 14:19:58 -0700 http://www.applefritter.com/node/23499 Hey there: Newbie on here. Thanx for receiving me. I have the above and they're all dead... the 2 SE30's and the Color Classic. The reason I have to resurrect them is because I have an old Xante Accela-Writer 8100 tabloid printer that is worth using and I can run it from these, hopefully as a print server via OSX later. Of course I would rather run the printer directly on newer macs, but the Xante/the printer company doesn't have drivers, so I'm limited to pre OSX and appletalk at this point. BTW, I doI have all the gizmos including the keyspan serial to USB, the Asante talk serial thingie, and the use of an old iMac that still runs OS 8. Right now all I want to do is somehow make these old SE30's and a Mac Color Classic actually fire up. They are completely dead. I tried to fix the youngest of these, the C Classic with a PRAM battery, but still nothing. I wonder if the power supplies all simply die forever after a specific period of time. I still have the old serial keyboards, mice, etc... Sad girls all of these. I remember that I actually paid $6500 for one of these SE30's and that was before I upped it to 8 megs of RAM for $800 each. Oy. Thanks in advance for any advice to get these girls running again... BTW, I don't think it's the batteries. I'm going to take them all apart in the next few days via long torx etc. and who knows. Regards you all, Ray Swanson Vancouver, Canada Wed, 01 Oct 2008 00:04:41 -0700 http://www.applefritter.com/node/23447 I've got a short/dumb question for any "redneck" hardware hackers/Powerbook experts out there. Over the weekend in a "one for two" exercise I put together a working Powerbook G4 (Aluminum 15") out of two mangled donor machines (drop victims). It's all good for the most part, other then one thing: Both machines landed face-down and cracked some internal connection between the screen panel and the horizontal bit housing the hinge proper. Thus my Frankenstein creation has a slightly wobbly screen. It's not *bad*, but it's just enough that it'll sometimes make somewhat disconcerting popping noises when moving the computer. Anyway, I'm thinking of fixing the problem by running a bead of J-B Weld or similar epoxy along the joint between the two pieces. It's a decision I'm sure I'd regret if I ever have to replace the inverter board housed in the hinge, but I can live with that. (I'm basically betting that the electronics will outlive the machine's usefulness, a fair bet given how the G4 is pretty grossly obsolete already.) I guess my two-part question is: A: I've been looking at the PowerBook Medic's disassembly guide which shows how the hinge bit attaches to the rest of the display and it looks to me like for it to wobble like this it's legitimately broken and there's no point in ripping apart the display housing to try to fix it some "right way". Is that probably a fair assessment? B: Does this sound like a reasonable plan, in that is it likely that a quantity of epoxy that'd still let me close the lid would be strong enough to hold against the forces of opening and closing it? I don't have much experience with it. Thanks. --Peace Mon, 22 Sep 2008 12:13:10 -0700 http://www.applefritter.com/node/23444 Hi all, I was using my powerbook yesterday when it died. The screen shut off, but you could still see the last image stuck on the screen even though the backlight was off. Even though the battery was in, the computer fully shut off when i pulled the power cord. Now, if the battery is in and I turn it on, I get nothing except a very quiet fan noise. If the battery is out, the optical drive spins up and the harddrive does as well, but there is no chime and the screen stays black. I'm thinking logic board. What do you think?

Have attempted to start the MAC OS X Install disk, but it does no recognize it is in the CD Drive. Any ideas? Mon, 15 Sep 2008 14:44:29 -0700 http://www.applefritter.com/node/23366 hello for the first time I'm wondering if anyone would know where I could find a guide on how to disassemble the whole thing and not just for to upgrade the ram? thanks very much Wed, 03 Sep 2008 08:08:10 -0700
