I'm somewhat new to the forums, and found a really good deal for a brand new macbook air (rev.1). I'd like to know if it is possible to replace the logic board in my macbook air with a newer, nvidia-gfx based logic board. As in, will it fit, does the same power supply run it, same peripherals (airport, keyboard, etc) work/interface with it, etc?
View 5 Replies View RelatedAs the title implies, I've got 3 year old G5 iMac sitting as a paperweight at my desk. At least half that time ago the logic board died and I was quoted a repair bill of around $900. I couldn't go with it, but I couldn't decide what to do with it either. I now have to get rid of it and since I know that this model had lots of issues with logic boards I'm hoping some of you will have some good advice.
With the new iMacs finally with us, I wanted to get myself one of them and, while I am at it, maybe replacing my current PC as whole. I tried to find a good comparison online, but somehow Google didn't return anything useful. So...
Can anyone tell me how the new iMac's GPUs against my "old" GeForce 8800 GTS?
I got a mac mini out of warranty (core 2 duo 1.83 ghz) that just died on me. I went to the apple store and they sent it in for a diagnostic. They confirmed that the logic board is dead and will be around $350 to replaced. I'm still weighing my options and was wondering if anyone can direct me to a site that sells replacement logic boards to see if I'm better off doing the repairs myself?

? the logic board of my iMac failed. It was replaced by Apple, but they couldn't tell me why this had happened. Looking for answers to avoid future problems.

Am having a problem with the screen getting "messed up" is the best way that I can describe it. Happens with all different apps running but nearly always shows up when trying to edit a photo in iPhoto. When I make an adjustment there (like sharpening) the photo will turn all red and the system will lock up. This does not always happen, but just most of the time. In other apps, it can result in just messing up that page or the entire screen. I can replace the Graphics card myself if that is what the problem is but is there any way to test it before laying out the $250?
View 5 Replies View RelatedMy 17 inch iMac G5 1.8ghz seems to have died. For a while it's been refusing to power up and then powering up randomly but now it wont power up at all. I've looked on the logic board and reset the SMU etc but I can only get the first LED to light up. I think this means the logic board has died. Is it worth replacing the logic board and can it be done easily myself? Or should I just bite the bullet and pay out for a new alu intel iMac? I'm in the UK btw, any ideas on logic board prices?
View 1 Replies View RelatedMy G5 iMac is getting a new harddrive, meanwhile I had to fire up my older front, slotload IMac (G3), it has 10.3.9 installed and 250GB external harddrive. Unfortunately, this little iMac only has 30GB on board memory. After the 10.3.9 install/upgrade I only had 4GB of available memory. I have looked through just about every file/folder to delete duplicate/unnecessary files but cannot find what has used up the memory. I have a LaCie 250GB external drive, partitioned in three sections at 78GB each; can I install OS X on one of the partitions and work from that for my Photoshop, Illustrator and other graphics software projects?
A few minutes ago a message came up saying that my memory is close getting full and should clear some files to make room. This iMac (slotload) is only rated for 512MB RAM max at 133-333 speed, two 256MB boards (max). Is there a way to get around this and add more RAM, a way to boost it to768MB RAM or even 1GB RAM and still have the system work and utilize the extra memory? Do I need the adapter to run a mirror monitor on the slotload (a 17" flat panel, mac compatible, ViewSonic brand. I have the software to set up the mirror)?
Have an early 20" iMac G5 and the Hard drive started to squeal and then crashed. Tested dive in another iMac and it is definitely bad. Installed new hard drive and the system fails to find it. Formatted it on the other iMac and reinstalled but it still is not seen by the system. Everything was running very well until the drive failure. Took it to an Apple approved store, paid the $60 to be told that the Mother Board was bad. It is hard for me to believe that a disk failure could cause a Mother board failure. 2- 20" iMacs, a 24" iMac, and a new 27" iMac (not yet out of the box.)
View 1 Replies View RelatedI can't seem to figure out how to remove the logic board from a G5 w/iSight that I've been given to have a look at. What happens is that the unit powers on, the LCD display slightly brightens (getting power) but stays dark, and that's it. No beeps, boops or other responses beyond that. If you remove the RAM chips, the LED power lights gets mad and blinks at you, but that's about it. On the board itself I get the two diagnostic LEDs lit. The third never even flickers.
View 3 Replies View RelatedMy iMac died a few days ago. I shut it down the previous night, and then in the morning when I went to turn it on, nothing happened. The screen display doesn't turn on, nothing. I opened it up and did the LED tests, and found that the first one would turn on, but none of the others would. The apple site says to take it to a store and have it fixed.
Now, I bought my mac on December 19th, 2004 ( what a day that was). At the time, I didn't think I'd need to buy applecare or anything. So about how much do you guys think it would cost to replace the logic board? And also, how long would it take to have it replaced?
i need some advice on what to do next, my Intel 24" iMac has failed, diagnosed as a faulty logic board by the Apple Genius. I purchased the iMac in Dec 07, and I deliberately did not purchase the extended warranty as this is a desktop unit, that in 20 months of ownership has never been moved, dropped or transported anywhere.
I have no option than to either pay for the repair - �380 or sell on eBay for spares...!
I informed Apple about the Sale of Goods Act, and they have put the owness on me to prove it was faulty from date of purchase...! They have informed me that I need to visit an Apple authorised service centre where they will run a test and produce a report, which will determine if the fault was there in the first 6 months of ownership.
I've recently been having problems with my iMac G5 iSight after downloading iTunes 9. After a series of freeze-ups, i noticed a visual anomaly appear on my screen. Little hash-marks all over the display were present, and playing DVDs or iTunes visualizer would result in a checkerboard pattern. After doing some research, I found out this was a logic board problem, and it was not uncommon for iMac G5s. However, I kept using my computer for a few more months when it then started freezing two minutes after boot up. I figured it was time to open up the computer and take a look. But after spending the 3.5 hours opening the machine, removing all of the cables and screws, I couldn't find any visible damage on the board. No swollen capacitors like everyone was complaining about. The only strange thing I saw was some discoloration on a few circuits near the USB and Firewire outlets.
I've decided to replace the logic board myself for around $370, and I was wondering about a few things.
1. Would the new logic board come with a processor, or would I need to pry it off of my old one, and re-attach it?
2. Would I need to go through a lot of re-programing and software issues if I replaced my logic board, or would it just start running right off the bat after replacing it?
3. Is this operation worth it? Because I have come to like my iMac after 5 years of use, and I would like to know if fixing it would give me a decent amount of usage before I would simply need to replace it
I have an imac G5 20" that is approximately two years old. About 2-3 weeks ago it started acting a bit flakey....it would lock up on std apps (firefox), it would always lock up after being revived from sleeping etc. I ran the hardware test and everything checked out. Then a few days ago it wouldn't boot. I get the chime, I hear the drive spinning, then the fans kick into high gear and I get a screen with a folder in the middle with a "question mark icon" and a "finder icon" displaying alternatively inside the folder. So I booted up the hardware test dvd and the test failed 27 seconds in with the following error code:
2GMC/2/15: built-in
Logic Board Error Detected
Are there any other steps I should be taking before taking in for service?
My iMac chimes when I press the start button but the screen doesn't come on. It's making a whirring noise so it's doing something. There's a DVD in it but it won't come out when i press the eject button on my keyboard. The iMac also doesn't show up on the network of my MacBook which it usually does. I was having a few problems earlier this week with the screen doing strange things - occasionally turning off, then coming back on. It was suggested that it might be a dying logic board but I tried a Apple Hardware Test this morning but it said no problems found. I have some files backed up but desperately need to get some recent documents off it [I know, I should have backed it up more often ]. Is there any way to get access to the files on the hard disc?
View 19 Replies View RelatedI've got a 20" 2.1GHz iMac G5 iSight on my bench that doesn't power up.
I've tracked down the issue to a grenaded IC on the logic board.
The IC is an 8 pin SOIC chip, to the right of the power connector, just above the ALS connector. It is labeled UE300.
If you know what this guy is, can send me a good picture of one, or can provide me with the numbers from the IC, I can get this mac back to life.
so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]
My son's 17" imac PPC G5 was not booting up. After a trying a couple of things I got it to boot using Disk Warrior and reparing the file directory. At that time I also ran DW's hardware test which said the drive was fine. My son hard restarted it shortly after I fixed it and it wouldn't start up again. Just a gray screen, no apple logo. When I tried to use DW again it told me there were problems with the hard drive and it couldn't fix the problem. I tried to fix the hard drive in target disk mode using Disk Utiltiy and Drive Genius. No luck. So I pulled a working drive out of my Mac Pro and reformatted it and swapped the internal drive of the iMac with it. There were no DIP switches to set. Started up the imac with a Leopard retail disk thinking I would just install a fresh system onto the replaced internal drive of the iMac. Disk Utility on the leopard disk didn't see the hard drive. Now I'm beginning to think it's a logic board problem but I can't find the original disks to do a Hardware test with. Is there some other way to test a logic board? Or some other idea that I'm not thinking of that could be wrong with the machine?

Does the logic board serial number match the computer serial number?
My reason for asking is that 4 months ago my sisters G5 17" logic board supposedly got replaced with a new or refurbished logic board but it seems by the workmanship of the board something fishy is going on.

I am new to apple, just purchased an iMac off craigslist, and have a personalization question. I was able to change the user name and all that info just fine but when my computer first turns on and I am prompted to log in the previous owner has a text below the apple icon that I would like to change. Right now it says "Daves ********** iMac" well my name is not Dave and I don't care to have that on there every time i go to log in. I have done a lot of searching and found where I can "change login text" but that is for one of the texts, not the one I am trying to figure out.. here is a sample picture, the text I have circled in red is the text I am trying to change, the text saying macbook pro is the only text I have successfully changed. (This is just a picture I got off the inter-web, not my actual login)
