Ethernet Cord not being detected by 2008 Macbook Pro

My macbook pro that I purchased late 2008 is no longer seeing that it is connected to an ethernet cord. Other computers can connect to this cord though and work fine. Is this a problem I would have to bring my computer into a Mac store for?

If you would like it fixed then yes. Rarely have I seen Ethernet chips go bad but it does happen.
First try a different cable, I know you said the original cable works with other computers but just try it.
Second look inside the Ehternet port on you Mac. Are all the wires/pins straight?
If not that could be the problem, they got bent somehow and are now not connecting properly to the cable.
You couls try moving them back into the correct position but in the end you may need to take it in to be fixed.
Problem is that port is soldered onto the Logic/Mother Board and the only ay to fis it is to change out the Ligic/Mother board whih is expensive.
Good Luck.

  • I have an external hard drive and it randomly stopped being detected on my macbook pro

    Hi, I've got a seagate backup plus external hard drive that randomly stopped being detected by my macbook pro for no reason. I've tried it on my friends macbook pro and it works fine, his macbook is just about identical to my macbook. Help would be apprieciated!

    Here's my lo-tech solution (if you have Parallels) to this frustrating problem:
    Eject your hard drive.
    Unplug (USB) your hard drive from the MAC .
    Start Parallels.
    When Windows has started, plug your drive back into the MAC.
    You should get a little screen asking if you want the drive to be utilized by MAC or Windows. Select Windows.
    Use Windows to copy your files over to the hard drive.
    This is less than ideal and not a long-term solution, but I was afraid of attempting any reformatting since I have many files on my hard drive. 
    Just remember that Windows has to be running first, before you plug in your hard drive.

  • My SD card isn't being detected by my MacBook Pro

    My SD card isn't being detected by my mid 2012 MacBook Pro. It's detected fine by my camera and my iPad (using the Camera Connection Kit), but not my computer. I've tried it in both OS X Mavericks and Windows 8.1 using my Boot Camp partition, but it's not being detected at all in either OS. This has worked before just fine.
    Does anyone have any suggestions on what might be wrong and how I can resolve it?

    I too facing the same problem after installing Mavericks. I tried opening iphoto first and then inserting SD card, that also doesnot detect. waiting for other solutions......thanks in advance

  • Why, since upgrading to iTunes 11, are my devices not being recognised on my MacBook Pro?

    Since upgrading to iTunes 11, my devices (iPhone and iPad) are not syncing or being recognised when connected to power. Now for wifi syncing, I have to disconnect the devices from power before they are available on my MacBook Pro. Any ideas? This is really weird.

  • My iPod Nano is no longer being detected by my MacBook Pro

    It does not show up in my device list so I don't see it in iTunes on my MacBook Pro. Nevertheless I can see it on my wife's iMac... but I don't want to sync it with her computer but mine! I wonder if I took it off the list by mistake when I thought I deleted my Mini iPad... How can I get it back so I can start syncing again with my MacBook Pro?

    I have the same issue. Ever since the "auto security update" my iPod shuffle and iPod Nano do not show in iTunes. I know the "auto security update" is the culprit, as these devices were not showing up on the iMac. I tried them on Macbook Air, and they showed up in iTunes, that is until the auto update installed on the MacBook Air. After the updates, these iPods do not show up under devices in iTunes. They are however visible on both my mac's in the desktop. Please help.

    iPod Nano 6th Generation.
    PS. I though I had done something wrong, and deleted iTunes, and reinstalled iTunes. Reset my iPod Nano, etc. Tried everything, I am now stuck with 2 bricks as of now.

  • Ipod shuffle (2nd Generation) is not being recognized by my MacBook Pro or itunes:

    I was recently given my friends old ipod shuffle, but it is not being recognized by my computer at all, is there something that I can do?

    What have you tried so far in terms of troubleshooting? Did he give you the cable that was originally included witht the Shuffle? I ask because if you are using a 3G/4G cable it will not work with the 2G Shuffle.
    Have you worked through all the sugguestions here as necessary?

  • Email not being imported into my MacBook Pro - SSL error

    My email accounts that I monitor thru the mail in my macbook pro are now not working or updating.  When I read the error message it states that I might have to turn SSL off if my server does not support it.  I read Eric Roots suggestion on how to turn off SSL but when I follow his instructions I can not edit the SSL selection to uncheck.  My mail has been working fine by importing 5 email accounts into my Mail Application but since May 9 it has quite working on my Macbook Pro.   The mail app works fine on my ipad and my iphone.

    Out of frustration I finally completely shut down my MacBook Pro and waited 30 minutes then turned back on and majectly all of my email accounts imported into my Mail account.  Still not sure why this happened.  I use my MacBook as my desktop so I leave it on all the time and wonder if this may be my problem.   Thanks looking at my question but no answer replies but this seemed to fix my issue.

  • Ethernet Card Not being Detected on my iMac 27Inch (Mid2010)

    Hello,
    I have only had my iMac for a couple of months, and it appears to have developed a fault. I have a network router, and a network cable is plugged in however, the Network Panel keeps reading as "Cable: Unplugged". It is not, i can assure you.
    When I got into the About This Mac > System Profiler, it has "This computer does not appear to have any PCI Ethernet cards installed." under the Ethernet Card option
    I'm currently on Wireless (very skechty), and that also keeps dropping out even though the router is less a foot from the iMac.
    Any Solutions or Advise please?
    Thanks Phill C

    I have the same problem after I installed LION on my imac 27" (Late 2010). It was working for few days and then after I restarted my computer my network card just went dead. Since I have several partitions I can boot back to Snow Leopard and it shows me ethernet just fine. So it means that LION has bugs and many bugs from what I can tell. It is wide spread problem and not sure if apple is doing anything about htis.

  • Ipod 4g 32G not turning on, not charging (on multiple cords, both comp and wall, 4 20min), not being detected by Itunes or Windows 7 64bit OS, will not reset, tried taking it out of "DFU", NO DMG, Itunes up2date, All I'm getting is a blank black scrn

    Ipod Touch 4th generation 32G not turning on, not charging.
    I have used multiple cords on both computer USB and wall USB converters. I let it sit there for over 20 min with each attempt.
    It is not being detected by Itunes or my Windows 7 64bit OS. I have tried all 4 of my USB ports (both USB 2.0 and 3.0), with 3 different chargers.
    Holding home and power button will not reset.
    Tried taking it out of "DFU" mode but Itunes won't detect it, I didn't think that would work anyway.
    NO DAMAGE, I have been very careful with it, aside from a few minor scratches. (that you can't even see unless the light reflects them)
    My Itunes is up to date, as is my OS.
    All I'm getting is a blank black screen. It has been working fine on this computer before. I have no idea what could have happened. I'm at my wits end here.

    See if you missed anything here:
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable              
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • 2008 Macbook pro left click not working properly after upgrading to 10.6.8

    I have a 2008 Macbook pro and a few months ago after upgrading to 10.6.8 my left click has been wonky.
    Using the trackpad the left click eventually gets "stuck" or stops responding and I have to push it multiple times before it does anything.  I have tried plugging in a mouse, but when I do so the mouse also behaves the same way.  The only way I seem to be able to get the clicking to work properly is to restart the computer with the mouse attached.
    I have seen threads about trackpads being messed up by swollen batteries, but my battery is brand new and looks fine, and the clicking problem extends to an external mouse, so I believe it is something with the preferences.
    I tried deleting  com.apple.driver.AppleBluetoothMultitouchTrackpad.plist   and restarting and the problem seemed to be fixed, but then after about a half hour it returned.
    Having to keep a mouse plugged into my macbook is driving me crazy, anyone know a solution?

    I started having the same issue after update.  I'm on a MacBookpro running 10.7.2
    ICalled apple and they did a remove battery reboot, a reload lion and a option/command/R/P reboot on startup and then the computer started working.  Two days later problem was back.  I then did a reboot and the computer was back to working.  Today the computer worked fine tell it went to sleep.  I had to do a hard reboot to get the Mac up and running and now no left click.  Please help. I can not use the Mac  with the trackpad, a mouse, a Bluetooth mouse, or a digital pad. All so signs of left mouse click not working.  One other item when you go to pick your user at startup the left mouse click works.  Help!

  • My Ipod Nano 5th generation is not being detected by Widows and Itunes. I have tried everything based on the trouble shooting tips outlined. Has anyone had this situation before? How was it resolved. My Ipod is just out of warrenty

    Have done all trouble shooting tech a through Apples and still have not resolved issues on Windows and itunes not detecting my Ipod  nano 5th generation device. Tried restoring the device manually using disk mode and still not being detected by the computer. Device is our of warenty as when service repair charges are $125.00 dolars more than I paid for this device. There must be some way to restore the entire device to factor settings without having to be connected to itunes and Windows. I wish I could connect but again device is not being read. I have another Ipod that is 8GB instaed of 16GB and it works fine. The sad thing about this situation is that my 9year old daughter worked hard doing delivering fliers for a long time to save her money to buy this 16 GB 5th generation Nano. Otherwise the Ipod works well but will not syncronize songs as it is not being detected. Maybe this is a result of corrupt files that got onto my daughters Ipod somehow and thus causing it not the be detwected through the USB connection thus as a result not be understoud as a working device through Windows and itunes. If anyone can help me out there including itune techs that would be well appreciated, but for now my daughter is not able to add new or delete any songs on her ipod as well pictures, and everything. Thanks

    Try changing the cord. I could NOT get my computer to recognize my iPod 5th Gen until I read somewhere that different apple devices use different cords. I was inadvertently using my iPad cord and that caused my computer to not recognize my ipod.

  • I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

    Things to note:
    I have been unable to update firmware on this computer for about a year now. Im not sure why.
    I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
    any thoughts on the matter would be greatly appreciated, thank you.

    Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
    It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

  • I have a late 2008 Macbook Pro last updated to Mavericks OS.  The screen died and it's not worth replacing.  How do I remove the hard drive and use a drive sled to access info I need?

    I have a late 2008 Macbook Pro last updated to the Mavericks OS.  The screen died and I took it into an Apple store and was told replacing the screen and the hardware to repair everything would cost almost as much as buying a new laptop or a cheaper model.  I was told that I can use a drive sled to access data I need on my hard drive. How do I remove my hard drive and use a drive sled to get to the information I need?  What makes matters more complicated is I need to update my iPhone and my iTunes/App store purchases.  How can I accomplish this?
    My wife has a late 2008 Macbook Pro as well, which I am assuming I need to run my hard drive.  Is there a way to just access just my hard drive without interfering with hers?
    I know this is lengthy.  Thanks to whoever looks at this and offers advice/instruction.

    the device you need is an External enclosure for a 2.5" (laptop form factor) SATA drive.
    A USB-interface enclosure will be slow, but is adequate for this task and for re-purposing as a backup drive later.  A firewire-interface drive would be faster, but is harder to find, more expensive, and faster than needed for this purpose.
    The drive will mount as an "extra" drive on your wife's Macbook, and you can drag and drop whatever you wish. You could create a separate Account for yourself on her computer, and use Migration Assistant or just copy your stuff over to the new account. Then it would not interfere with her files.
