PM G3 AIO Blown logic board?

Hello everyone. I have a Power Mac G3 AIO running OS 9.2 that I upgraded from 233MHz to 300 MHz Apple orginal processor by exchanging the ZIF processor and resetting the jumpers. It was working very well and I should have been happy with it. But then, I decided to upgrade it to a 400 MHz ZIF original Apple processor and also reset the jumpers for the 400. But at the same time, since I had the logic board open, I also installed a PCI USB card. I then pressed the reset button on the logic board. Then, when I powered it up, nothing! I mean there is power running through the machine but no startup chime, no monitor, just the onboard fan running. I tried resetting the PRAM, but still nothing. I tried going back to the 300 processor but nothing. I have not tried going back to the 233, should I try that? Did the logic board fry when I did both the 400 processor AND the PCI card at the same time? Please help!!! Thanks.

First step- don't panic. You don't seem to be.. that's good =]
Allen's covered most of the bases. You also might want to consider a PRAM zap (or, in this case, maybe a new PRAM battery).
First thing's first, though: Take out the USB card. Is it a Belkin? They've been known to be problematic... Allen got more specific with chipset, which I don't really know about... I guess Belkin maybe uses those, then.
Now, when you went back to the 300 MHz CPU, did you remember to reset the jumpers? If not.. well, no matter what you do, odds are you aren't going to be able to get a 300 MHz G3 to boot at 400 MHz.
A 400 MHz original ZIF would belong to a B&W G3 processor; they have a 100 MHz bus speed. I don't remember, and I seem to recall them working just fine in Beige G3s, but maybe I'm misremembering and they don't operate on a 66 MHz bus? I doubt that's the case. But perhaps.
Anyway, as Allen said, try seeing if you dont' need to reseat your "Personality Card" in its PERCH slot (the brown one on the right of the PCI slots). Recheck the ZIF's seating.. and also, don't forget to make sure you've put the heatsink on the right way.. if you put it on backwards, the piece of metal that holds it down isn't tight enough, and results in overheating.
I think you also need to hold down the reset button for at least 30 seconds (or is it 60..) for it to take effect, though I don't imagine you'd really need to.
Anyway, remove the PCI card... reseat the ZIF, making sure it's really in, make sure the jumpers are right, and make sure you didn't accidentally knock loose any cables (unlikely, but not impossible); this includes ATA and power cables.
If none of that works, try taking the PRAM battery out and putting it back in.. this effectively clears it. Or, if you don't care about your system date (don't mind resetting it.. takes a minute or so) and don't care about thinks like the total #hours your computer's ran, its manufacture date etc, just do that first thing.

  • Have a blown logic board...

    Well i dont have it yet, but i was just wondering, how easy is it to fix blown logic boards.
    From the picture i have seen it looks like a resistor near the processor.
    its a g4 1.33ghz board, and the blown one is just below the "G" where it says thermal gasket.
    Cheers for any help
    (oh im in uk in case going to suggest people to take it to)

    If you can do component-level board soldering -- or can find someone who can -- then it might be possible.
    Generally bad boards are just swapped out and repaired who knows where by specialists in fixing this sort of thing.
    Hope you aren't paying much for this.
    Keep in mind, that if one component goes, it can easily take others with it.
    IMHO it seems unlikely that it is a resistor that is blown. Usually it is capacitors that "blow".

  • Intel Imac with bad logic board.

    The logic board on my 20" Intel Imac failed(according to the diagnosis form the tech at the Apple Store) and will require a $900+ dollar repair....a tad bit high considering it's age, the cost of the machine in late 2006 and the going prices of the new Imacs! Anyone know of a lower priced repair option or a way to salvage the machine, or is it now a very large paperweight?
    I know that I apparently should've gotten Apple Care, but I've never had such a catastrophic Mac failure in the 12 years I've been dealing with the machines. Judging by the lines/wait for service at the Apple store maybe it's a good idea next time...although with all the problems the new machines seem to be having it seems a bit like extortion and maybe they should just raise the prices and include it.

    I have a similar problem that I'll describe hoping that it will contribute to this discussion and I'll ask a couple of questions. In December 2007 I bought an iMac 24 inch maxed out for speed and RAM and with the 750 gig hard drive. I had no problems until about three weeks ago when on startup I got grey hash marks all over the screen. When I selected the entire screen the grey hash disappeared and the computer seemed to run normally. I thought the problem was software related and began the long process of trying to find the culprit. Then two days ago I connected a video camera to the iMac to test the camera for the first time. It's a loaner from my school and is five years old. It seemed to be working fine. I then turned off the camera but left it connected to the computer by the firewire cable and put the computer to sleep. THAT was probably a mistake. When I tried to wake the computer it would not respond. There was a DVD in the machine and when I pushed the power button I could hear the DVD player makes it startup sounds and could hear the CD spin. Also I could hear the fans come on but the startup BONG never sounded. I disconnected all cables, pulled out the power cord for various lengths of time from 30 seconds to ten hours but nothing changed. I called Apple this morning and was told it sounds like a blown logic board which is what I was thinking. They will pick up the iMac day after tomorrow. When I talked to the Apple person this morning it didn't occur to me to ask about my chances of getting this repair done for free since I'm still within the one-year warranty period. I'll call when they open tomorrow morning but what are my chances of getting the repair done free? I've been using Macs since the Mac Plus came out but have never had a failure within one year so have no experience with the warranty. I did not buy Apple Care for this computer and never have but I will the next time. Thanks in advance for any comments.

  • Classic AIO and Powering on w/ no logic board

    What happens if I turn on any Classic AIO (Color Classic, LC 575, Power Mac 5200, etc) without a logic board?
    I ask this because all above models have a rocker switch but yet it is software controlled (Power Key.)
    Does it do anything or is on standby waiting for response from the logic board? Has anyone expiremented this?

    This is what they wrote on my genius bar work authorization exactly:
    Issue: Computer boots to the apple logo and spinning gear, but then freezes up completely and the fans blow continuously. Occasionally kernal panics. Steps to Reproduce: verified at bar. Attempted SMC and PRAM reset. Upon trying to run AHT, it would boot to open firmware and give an error for "Invalid Memory Address"
    Proposed resolution: check in for ASD for $85. Ordering RAM
    Cosmetic Conditon: normal wear
    I paid for them to run disagnostics and they said they did but my apple store is pretty bad. They're always beyond busy and full 24/7 so there have no patience. When I call, there's at least 20 plus people ahead of me. Even with appt, wait was almost 2 hrs. They said 3-5 day turn around time. I called on day 5, nothing. Day 7, transfered to a genius who said "oh Randall took a look at it, did diagnostics and you need a new logic board. It's gonna be pricey though it's around $1100 and for $50 more you can get a new one." I said, "are you sure?!" He said, "Yeah, that's what Randall wrote." I should've asked more questions, I know, but I was in disbelief. Unfortuantely I had to pick it up with my boss who was in the biggest hurry of his life with every inch of the place so I had no opportunity to ask.
    It does chime at boot up. I got a system failure message on the grey screen that said basically:
    cpu=0
    code=00009 (invalid pmap)
    latest crash info for cpu 0: exception sate
    BSD process name corresponding to current thread: kernal task
    panic: we are hanging here
    And then the fans run and it won't go any further. I've had the alert about the startup disk a couple times but I usually kept it with 15GB always free so I hadn't seen the alert in awhile.
    Could not get a safe boot either. What do you think?

  • G5 Logic Board or Memory Issues?

    Hello, about 2 months ago i recieved a 1GB Dimm for christmas, and being naive, i installed it in the slot above the 4 512MB RAMs that came with my computer. When the computer didnt recognize it i looked in the manual and found out that you are supposed to install them in matched pairs. Figuring i would lose the memory i left it in the computer for about a month. Then the trouble started. When waking from sleep or screensaver i would get the spinning color pinwheel which would NEVER stop and i would hard start using the button on the front. Problem was that the computer would not boot back up for hours. I would get to the grey apple screen and then after that a blank blue screen with the cursor, and that is as far as it would get. If i tried hours later it would eventually start up. When i decided to remove the 1GB RAM chip the computer worked for about a day then started the same problem. I wiped both my drives to zero and installed the system on my second drive. Again it worked for a day and then the same problem. Once the problem started it hasnt stopped yet, i cant get into my computer at all now and it has been several days. It wont boot from ANY volume. I brought it into Tek Serve in NYC and the said it could be the processor or logic board, but they wanted 700-1000 dollars to fix it. So i took it home and ran the apple hardware test cd. I ran the extended test first, then the quick test. Both times it said my logic board passed, harddrives passed, but when it got to the memory section it took a VERY long time, and eventually CRASHED my computer the screen turned into millions of bright colored bars and i would have to hard re-start it. Thinking it was bad RAM i removed all my RAM, and re-installed it in different orders and taking my computer from its factory 2GB down to 1GB to see if any of my chips had problems. I also hit the reset button under the RAM but it still never started and still had the same problem. So as of now i dont have a working computer, i called someone at apple tech support and told him the whole story. He said i should bring it it somewhere and maybe by putting in the extra mis-balanced 1GB chip maybe i overloaded my RAM sockets and fried that section of the logic board. Has anyone heard of this happening? I am reallly lost on this whole thing and would rather not pay $1000 to fix it (though i think maybe Tek Serve is just really expensive), but obviously a comparable new mac is 3x that amount anyway. PLEASE let me know if there is anything else you can think of, or let me know if i could have maybe infact overloaded my RAM and blown the logic board.

    You can go to the Apple Support page and click on Check my Warranty, then enter your serial number (found in "about this Mac">more info) and you will see how long you have left on your Apple Care.

  • Grey Screen at start-up - Troubleshoot harddrive and/or logic board?

    Hi everyone. Sorry for the lengthy post, but hopefully you can help me - I've spent a lot of time on the boards already, but hoped you could clarify some things.
    The problem is my Powerbook will not get past the grey screen at start-up. It will not boot off the 10.5 install disk and I can't eject the install disk to run the hardware test disk. Removing 3rd party ram, resetting PRAM, NVRAM, attempting to boot in 'safe' mode haven't helped. The harddrive is softly clicking/searching.
    So some questions:
    1) Is it possible that an interrupted time machine backup will bork the drive to the point where it wont boot? (See back-story below). I wouldn't have thought so, but prove me wrong.
    2) Should I be able to boot from the install disk if the harddrive is stuffed?
    3) If it is hardware, it's either the logic board or the drive. Is there any way to determine what it is (eg: is it possible to do a remote hardware test?)
    Edit: Just tried mounting the drive in target disk mode using an iBook, but it wouldn't mount. Powerbook displays a black screen.
    Oh, and I should point out that this is well out of warranty and any fixes would have to be cheap : ). Basically I need to determine if it's the drive or the logic board, preferably without having to buy and install a new drive when it may not be the problem.
    Any help or advice would be appreciated.
    Cheers
    - Ben
    Here's the back story if it's any help; recently upgraded to 10.5, created a base install disk image of all installed and registered apps (in the event that my drive failed). Copied data etc from the previous system over. It ran fine for a few days. This morning I ran time machine for the first time, left the computer for a while, came back and the screen was black (as if it was just displaying black, as opposed to off). Thinking it was just a display issue (which I've seen before), I put the system to sleep (power button, then 's'), woke it up again; still black. So I forced a shut down (wouldn't allow me to do a normal shut down, because dialogue boxes must have been preventing it) and on boot I got the grey screen.
    -------

    Hi Ben W. I don't have a good answer for you, but based on your information and what you've done, I think I would try starting the machine after disconnecting the harddrive. That requires taking the top off first, for which instructions are on ifixit.com.
    I can conjecture that a blown HD is preventing normal operation, perhaps sucking the power down, disrupting the optical drive, etc. This is purely conjecture, but costs you nothing but your time. If this turns out to be the case, I figure the optical drive should start responding again (hold C key during reboot, etc).

  • Macbook Pro 13" 2011 Logic Board Troubleshooting

    I have two 13" Macbook Pros, both with the same issue. They are both i5 (2.3 or 2.4 GHz models), 4 GB RAM, Mid-2011 models. Both of them have also been dropped. I believe they have problems with the logic board. When I try to turn it on, nothing happens. The battery does charge I believe, as the battery reports fully charged with the battery button and the MagSafe connector is green when plugged in. When attempting to power on battery alone, nothing happens at all (no lights, no movement, no noises). As soon as I plug the MagSafe adapter in (without pressing the power button), I get a very faint 'ticking' noise, which I have deduced to be the fan's motor VERY slightly receiving power (as if you put your hand on the center of the fan's 'blade' assembly, you can feel the motor very very slightly 'push'/pulse, but not enough to even move it; about 1 second between pulses. I have tried:
    -Powering on with no adapter, but battery
    -Powering on with magsafe adapter
    -Powering on with no battery but magsafe adapter
    -Resetting SMC
    -'Bypassing' SMC with 'Hold power then connect Magsafe' method
    -Jump starting it (with the two pads)
    -Reading the voltage from the pads used to jump start, 3.4-something volts DC (seems correct).
    -Powering on with no RAM (had no different effect)
    -Jump-starting with keyboard disconnected from board
    Any other ideas where to go with testing from here? I just find it odd to find two that have the exact same (specific-seeming) symptom, from the same sort of damage, with no idea what's wrong. Could it be a fuse, possibly, blown by a short with the case from the fall (even if momentary)? If you have any suggestions for fuses to test or if this seems correct, please suggest them.
    To be clear, I am entirely comfortable with removing any/every component in the laptop, if needed, and can work a multimeter and various other diagnostic tools (if I have them). I'm just not too familiar with this particular model's layout and could use some assistance from a more experience tech in regards to Apple products.

    Hello, thank you for your reply. I have been using their vast collection of knowledge, and I do believe I've already gone further with this than the information they have/general knowledge floating around the web will take me. I have checked, and I do have power across G3Hot (the 'Jump Start' pads), 3.47v DC, so I am not willing to accept this as a dead board yet. Next is to check MOSFETs and SMD capacitors I think, see if we've got anything toasted there. I did check every fuse I can find on the board. I also picked up some schematics from 'around' for this board, clearly looks enthusiast-made, but still better than nothing; one should think.

  • Does this sound like a bad logic board?

    Howdy everyone,
    Tried searching and troubleshooting but I'm at a lost for answers so maybe someone who has experienced the same thing could chime in.
    Our 2009 MBP started experiencing random beach balls a couple months back that gradually developed into full-blown lockups. Eventually the system refused to boot up so I figured it might be a hard drive problem. 
    I tested and verified the hard drive by:
    1) using disk Disk Utility to verify and repair the drive (completed without any issues and S.M.A.R.T. is 'verified')
    2) by installing the hard drive internally on a 2008 MB to see if it worked (booted up and worked just fine)
    3) hooking up the drive to the MBP via USB enclosure and booting up as an external disk (again also worked fine)
    Next I figured it would be the hard drive ribbon cable so I ordered and tried two different ribbon cables, one from an Amazon reseller and one from iFixit.  I get the same result with both cables.  The drive is recognized in Disk Utility but the system refuses to boot and gets stuck at the logo page with the spinning progress indicator.  Booting in verbose mode revealed nonstop disk0s2 i/o errors.
    I've ruled out the hard drive and the ribbon cable at this point so is there anything else that could be the culprit or does it sound like the logic board?
    Thanks in advance for any input you could provide.

    Hi Neurotic
    You maybe in luck, that 24" with the NVIDIA GeForce 7300 GT is rare and unlike most other iMac's can be refitted and with a new graphic's chip. Unfortunately the iMac is very difficult to open and work on, plus you may need an Authorized Apple Service Provider to locate and order the proper graphic's chip.

  • Is a bad logic board due to a bad power supply?

    Computer specs:
    iMac G5 20", 2.0 ghz, 1 GB RAM, 250 GB hard drive
    Back in October of 2008 my iMac G5 Power PC shutdown intermittently and then when I went to go to start it back up, it booted to the blue screen and hanged there forever. So, I did a hard shutdown and then waited and then booted again and it still hanged at the blue screen. I tried booting in Safe Mode, and that worked, so I had a chance to backup everything that I needed to. Then, I took the computer to my local Apple Store to speak to a "genius". They could not diagnose my computer while I was there, so they needed to take it overnight and let me know over the phone what the issue was. The next day they called to tell me that it was a Logic Board issue and that it would cost $900 to fix it. I obviously was blown away at the cost for the problem, and I could not afford that charge so I seeked out other options. I found a shop in my neighborhood that offered me a used 1.8 ghz logic board for half of what Apple was quoting me, so I went with it. Then, 9 months later (which brings us to present) my iMac completely shutdown on its own and would not start up. I ran it through some tests (LED lights on the interior) and confirmed that it was a Logic Board issue again. So, I took it back to the shop in my neighborhood and they told me that the warranty for the part they replaced had expired. So, I called Apple Customer Relations to talk to them about the issue. They confirmed, using my serial number, that I could get my issues fixed for free. They then told me about the "iMac G5 Repair Extension Program for Power Supply Issues" which was news to me. This Program ended in December of 08, meaning I would have qualified in October of 08... the time I initially brought in my computer. So, I brought my computer to the Apple Store to drop it off for repairs, and when going over the history of the machine they confirmed that because there was a used 1.8 ghz part in my machine installed from a non-authorized Apple place that they COULD NOT fix my issues now.
    My question is:
    Back in October of 2008 when I brought in my computer to the Apple Store and they diagnosed it with a bad Logic Board, could that have been because of a bad power supply? If that was the case, does a bad power supply cause a Logic Board to go bad?

    Welcome to Apple Discussions.
    The short answer is no, but it's actually more complicated than that. The original iMac G5 17 and 20 inch models were plagued by two problems: defective capacitors which affected the logic board, and an unrelated set of defective capacitors which affected the power supply. Rarely were both conditions present at the same time, but Apple decided—when they issued the repair extension authorization—that replacement of both components was a more cost effective approach. By far, the most common of the two problems involved the logic boards.
    The REA covered machines for a period of three years from first sale, and ended in December of last year. Yours likely would not have been covered due to the date of sale provision. On a case by case basis, AppleCare representatives did allow coverage for machines beyond the three year limitation, but not past the end of last year.
    It's not likely that you have both a defective logic board and power supply, though you may. The combination of these issues is actually found most frequently in the iMac G5 ALS models, none of which were covered by a repair extension authorization.
    Your issue is a difficult one, as Apple authorized dealers and service providers have every right—and, actually, a responsibility under their annual agreements—to reject warranty, AppleCare or REA coverage for parts or labor when compatible but not similar logic boards have been placed in your machine. This is because they must exchange these parts for the part they are requesting from Apple on a like-for-like basis, and that part must be associated with your machine serial number. In trying to resolve your issue, the shop in your neighborhood actually created an additional issue for you which would only be triggered in the event of component failure. I have no idea what period of coverage they typically offer, but Apple provides for 90 days or the balance of any warranty or AppleCare extension in place at the time of the repair, whichever is greater.
    Your logic board can be refurbished for $ 189.00 if it in fact exhibits the capacitor issue. That process is covered by a one-year warranty. If you are interested in exploring that option, send a message to the electronic mail address in my Public Profile and I will reply with additional information. To help determine additional information concerning your machine, please include the machine serial number if you elect to do write for more information.

  • G5 IMAC Logic Board Problems

    Hi basically my logic board has gone in my G5 Imac which is only 18 months. I have been told by an engineers report that ...
    The logic board has multiple component failure,the logic board capacitors have blown & discharged electrolyte on the circuitry an that this a know fault with this particular model..
    Now obviously my warrenty is out of date but i paid nealry £1100 for this computer having always owned macs expected it to last a bit more than 18 months.. any suggestions ..one company quoted me £500 ! this seems extreme do Apple have a policy of fixing know faults out of warrenty ?
    thanks

    Hi Kerrse - I would have to make the assumption you have an apple dealer or store there in the UK? Of course, give a ring or try this,
    "How can I participate in the iMac G5 Repair Extension Program?
    If you are located outside the U.S., please see Apple's international contact list for your local Apple Technical Support phone number."...
    your machine is on the list, Apple will repair it free of charge, just a little legwork is needed... hope this helps, Rick

  • Logic board serial swap desperately needed

    I just got the logic board replaced on my Mac Pro, and here's my problem: Over the years I purchased hundreds of plugins: VST plugins, Photoshop plugins, Final Cut Pro plugins etc etc, plus tons of apps. There is NO WAY I can spend a week reauthorizing and reserializing all this software without going broke. I absolutely need to replace the new logic board's serial number with the old logic board's serial number. My Mac Pro is from 2007, and I will stop using it as soon as Apple releases the new Mac Pros in 2013. In the meanwhile I still have to pay the bills with this old system and I don't care if the warranty is blown since soon it will just sit there for backwards compatibility (loading old projects in 2015 etc). Can anyone help? I know about Blank Board Serializer, but that only works with Logic Boards with no serial numbers. If I need to I will pay the money and buy another logic board and serialize myself if I need to, but I'm not sure it will work and I don't want to waste another $600.00.
    This isn't fair. I shouldn't be penalized for being honnest and buying all this software. If I had nothing but cracks on my computer, I wouldn't need to change the LB serial number since all the software would just work anyway. So why are the Apple folks and tech support guys so unwillig to help people like me?
    Does anyone have a solution? Is there a way to replace a serial LB number?
    Thanks,
    Jeeve

    Cloning the drive works beautifully, as long as the logic board is the same. Over the years I've used 3 different startup drives on the same computer. CCC has allowed me to save the weeks of re-serializing everything all the time.
    The dufus at the repair shop was lazy and told me he couldn't flash thew new logoic board. Now that I learned it is possible I will  take my system back to the show and make a scene, even if I have to pay for another blank logic board.
    I will contact Apple if this approach doesn't work.
    I never got an answer regarding softraid mirror, but that was before I realized CCC did the trick.
    I understand if it was possible for anyone to flash their logic board and change the serial number there would be mass fraud, but ironically in my case, I need to duplicate the old serial number specifically because all my apps were purchased. If I had cracks this would not be an issue because they would just work with any system;-) If the repair shop doesn't want to do it I'l have to get my money back and go to Apple. I have a few friends who had the same problem and Apple transferred the old serial number to their new logic board.
    In the meanwhile I'm just losing money because I can't work. So annoying!

  • Resolution of Logic Board/Airport card failure  - iBook G4 2005?

    Well, after my first post this morning, I was kindly advised to post a new topic regarding my kernel panics and not-so-nice grey screens of death!
    So here goes....
    I had experienced this problem since January, when my iBook purchased in April 2006 was coming up to it's first birthday. The problem was this - the iBook would freeze and i'd get a message stating that I needed to re-start. After re-starting, i'd get about 2-3 minutes of use, before the symtoms occured again.
    I had the logic-board and airport card replaced twice, by an Apple Store, back in January. The first replacement failed as soon as I got it home, the second replacement failed last night.
    So, somewhat dejectedly, I drove to Apple this morning, after booking a Procare session. I was expecting a bill of around £450, as that's what they quoted me back in January, if I had to pay for it. This time I would, as my iBook was 1 month out of warranty, with no Apple Care extended support.
    Upon arriving 45 minutes early for my session at the 'Genius Bar', I was promptly served, and advised the tech-guru guy what the issue was. Upon looking at the logs, he checked my warranty, found it had expired, then told me to 'wait', and disappeared into the back office.
    Some 5 minutes later, he reappeared, and simply said "have you still got the box for the iBook?"
    I did, but it was at home, some 45 minutes away. Then he said these magic words - "We're going to replace it, and give you a new MacBook, free-of-charge"
    I was blown away by this approach. I'd expected a repair, possibly a charge, depending on whether they realised that both replacements had been faulty. However, with a machine 1 month out-of-warranty, I did NOT expect a replacement machine.
    However, that's what I got. So, I'm composing this thread on a brand-new MacBook Intel Core-2 Duo, with the new spec 1GB RAM and 80GB hard drive.
    So, I'd like to take this moment to commend Apple on their outstanding customer-focused approach. Well-done on resolving my issue. Good luck to the rest of you experiencing similar issues.
    iBook G4 2005   Mac OS X (10.4.9)  

    Your ibook G4 (purchased april 06 probably being the 1.3 ghz model) was worth about 440 pounds second hand. The quoted repair bill of 450 was higher than the price of the machine itself, and you were going to pay it?
    There are unopened macbooks on ebay for 520-540 pounds (inc apple sales receipts+warranty).
    Them asking you for the box means they're going to con another customer into buying your broken machine.

  • New MBP logic board and wireless internet does not work anymore

    hi there
    i had to change the logic board in my only 2 years old MBP15". i purchased a new one and put it in by myself (relatively easy task). i still use the same internal HD as this one still works fine, so all data are the same.
    however, the new logic board has obviously a different "identity" from my old one, it came with a sticker which says "ethernet ID 001FF3513E7A" which is different from before. this may be the reason i can still access my wireless network at home, but the self assigned IP address prevents me from connecting to the internet. all settings are as before and it worked always without a problem.
    all settings were "automatic" before (using DHCP), and i use exactly the same settings again, but no success. i have to add that i use a new mac mini in the same network with absolutely identical settings (automatic) and this one receives a free IP address from the router (which is only in the last number different from the router's), but the MBP shows a totally different IP address.
    i could finally fix it switching to "manual" and adding the same IP address the mini is using and just changed the last number, which has to be different from the time capsule i use as wireless device and the mini. like this everything works just fine.
    but why does the mac mini perform everything automatic and the MBP (even with the new ethernet ID - and especially since i connect wireless and not using ethernet) is not able to do so?
    i worry if i want to use the internet in any wifi hot spot i may run into troubles...
    any idea what the difference between these two machines (with identical settings) is?
    thanks and cheers

    Thank you. It didn't work unfortunately :((
    Here are my router's details (Huawei):
    Product name HG655b
    Device ID 00E0FC-21530307237S0B028701

    I don't have Mac filtering enabled.
    Now it doesn't even find the wireless network anymore...
    My computer and itouch are connected to WAP, but the iphone could not connect to WAP, but only WEP.
    Any other ideas?
    Thanks a lot!

  • Has the NVidia GeForce 8600M GT logic board replacement program been extended by a year?

    I have heard that the logic board replacement program for MacBooks Pro with the failed NVidia 8600M GT chip has been extended from 3 to 4 years after the date of original purchase. However, a local AASP had no knowledge of such an extension. Is this true? I have a MacBook Pro 17" 2.6GHz that was purchased in 2008.

    when you took it in, it had been more than four years since your 2007 machine was originally sold, that's why you got the response you did.
    Actually it was within the time frame, it felt like it was just last month, when it was like several months ago.
    Just dragged the 15" recently out to see to use it for testing *cough* and low and behold it's worthless now.
    The problem I have is I told them at the Genius Bar the video was going, but couldn't prove it as it was very rare it occured.
    But they ran their little tests and gave me a load of crap, now it's dead. $2500 down the toilet.
    I know what did it, Lion. Lion was the cause, it ran like a fine machine under Snow, fscking Lion, I'm glad I didn't put that POS on my new 17"

    My word the OP, don't let the Genius Bar screw you with the same crap they gave me, call corporate and raise ****!

  • IPhone 5S 32GB Logic Board Repair

    So several months ago I attempted to repair the cracked screen on my black 32 gb iphone 5S on my own. It did not work out. I ended up breaking the logic board and now the phone is basically unusable. I've been using my iPhone 4S for the past few months and it ***** so bad. I just want my 5S back but now apple won't touch it and no one offers repairs for the logic boards on the 5S that I can find. Anyone know of a solution or someone who offers the service. Because I can't stand the crap battery on the 4S and I miss my 5S I had only had it for like, 2 months.

    I know of 2 services that repair logic board damage depending on your issue and your location in the U.S. One is eDigitalNY which is on the east coast and offers their repair services on eBay in addition to their website. They guarantee their repair work. Just ship them the logic board (shipping to and from is included in the repair cost) and they will fix it. If for some reason your board is "toast" and can't be fixed, they will refund your money. The second option on the west coast is The Repair Stop. Like eDNY, all repair work is guaranteed. TRS is a bit pricier but they are the go to guys for water damage repair, an area of repair from which many others shy away.
