Macbook 13" Core 2 Duo, Mini DVI to DVI will not work (Mini DVI to VGA OK)

I've recently purchased a used Macbook 13" with a Mini DVI out display port. When I try to use a Mini DVI to DVI adapter to an Acer X223W (or a few other Acer / Dell models), the Macbook screen either blinks blue to white constantly or doesn't do anything at all. When I use a Mini DVI to VGA adapter, it works fine, however, the MAC does not give an option for my monitors native resolution (1680 x 1050).
At first I thought there was a physical issue with the Mini DVI port, however the VGA adapter works fine. I've also tried a new DVI adapter in case the first one was defective - same results.
Am I missing something here? I don't think there are options to upgrade drivers on a MAC (I'm semi-new to the platform).
Thanks in advance!
Dan

What happens if you try just the monitor, e.g. keep the lid down on the MB? The MB should be attached to it's AC adapter to try this. Also, some kind of USB device will be needed to wake up the closed MB. Pretty much anything hot-plugged into a USB port on the MB will cause it to wake up. Would be curious to know if a DVI monitor works under those conditions.

  • DVI to video will not work- why not?

    I have a DVI to video adapter connected to my second dvi output.
    I am running it to a small monitor via composite cable.
    I can not get a clear image. The picture is black and white, distorted with crooked vertical black bars. It looks like it may be out of sync?
    I read the manual- it seems easy, but I can not get a solid image.
    How do I set this up?

    Hi Paul,
    In the displays preference pane, have you select PAL or NTSC as appropriate for your region of the world?

  • What will happen if I install Lion on my macbook pro core duo??

    What will happen if I install Lion on my macbook pro core duo? I have one of the first Intel MacBook Pro's with a Core Duo processer, I'm having hard drive problems so want to format it and re-install my OS. I can't find my Snow Leopard disk so the easiest thing to do would be to download Lion but I have been told that my MacBook needs to have a Core 2 Duo processer so I just wondered if anyone else has tried Lion on a MacBook like mine??

    Nothing.
    Lion will not run on a core duo, it needs a core 2 duo as a minimum
    see Technical Specifications
    Also you will need SL running to access the App Store to download Lion. So In a number of ways this won;t work.

  • Why can't install adobe illustrator on macbook intel core duo?

    I just bought the Macbook intel core duo, specifically so I could use Adobe Illustrator. I installed adobe CS2 and every program installed EXCEPT FOR ILLUSTRATOR! Tech support says Apple and Adobe are working on the problem. Can anyone help me?

    Welcome to the Apple Discussions!
    I've installed CS2 standard on about ten Intel-based Macs and and CS2 Premium on three Intel-based Macs at work. I haven't encountered any issues. No MacBooks at work though, just Mac minis, MacBook Pros and Mac Pro towers (which don't have the Core Duo chips).
    After reading your message here, I made a quick search of the Adobe support forums and couldn't find any messages there about anyone having a problem installing Illustrator CS2 on a Core Duo Mac of any kind.
    Our Intel-based Macs are all up-to-date with Mac OS X 10.4.8 and all the extras like QuckTime 7.1.3. Which "tech support" did you contact? Apple or Adobe? If Adobe is aware of the issue and is working on a solution, I'm afraid there isn't much we could do to help you here.

  • 802.11n for MacBook Pro Core Duo's no problem!

    From a post on xlr8yourmac.com:
    " So I was really ****** about only having G because of being an early adopter. So I started looking what could I do about it. Browsing the net, I found out that the new core2duo machines actually use a broadcom chip (Actually as mentioned here previously, the Core2Duo MacBook/MacBook Pros use the Atheros AR5008 Chip, although the Mac Pro uses a Broadcom chip (not sure on chip version no.) - the Apple 802.11n enabler supports both. See notes on Mac 802.11n page here.-Mike) and this chip is the same one in Dell Wireless 1500 adapters. (Dell notebook mini card)
    I bought one of those Dell 1500 cards on ebay, (I searched google and found the Dell 1500 card for as low as $52.xx, although an ebay auction had over 100 of them at $90 "Buy it Now" price.-Mike) and using the great guides on ifixit, change the card on my machine.
    (He didn't mention which CoreDuo Mac he had (Macbook? Macbook Pro? iMac? Mini?) but I'm assuming a Macbook or Macbook Pro since iFixit's guides don' t cover the intel-based Mini or iMac.-Mike)
    On boot, the card is recognized (and even more stable than the older one). The enabler didn't want to work (wouldn't install I assume he means) on my system though. So I opened it in pacifist, (available here-Mike) and moved the file to the System folder, and magic! I have draft-N in my macbook coreduo
    Hope you can publish this and it helps someone.
    -Julian"
    William

    Just out of interest, where's the third attenna?
    802.11n might work on the chip, but you won't get 11n
    performance without the third attenna.

    Ok, here is the scoop, I installed the AirPort Card from a Mac Pro and it works fine. I do have an issue with my Verizon DSL router Westell 327W. It does not like the new card. So I can not connect to it. On the other hand the AirPort Express and the new Mac Pro card in the MacBook Pro love each other. The range is unbeliveable! I am reluctant to update to the 802.11n enabler right now since reading all the problems with it in the other discussions.
    I am going to disable the wireless feature in the Verizon router and hard wire a connection to the AirPort Express and see how that works...
    So MacBook Pro (Core Duo) first generation can be updated to take advantage of 802.11n.

  • Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

    My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
    I have had this working previously but at the minute it seems to not be playing ball....any thoughts
    Thanks

  • 17" macbook Pro core duo = LCD LP171WE2 replace with LP171WU6

    Removed the cracked LCD  from my 17" Macbook Pro core duo 2.16
    The part # is: LP171WE2 TLA2
    Newer mac's use the following lcd part #'s:
    LP171WU6-TLA2, LP171WU6-TLB1, LP171WU6-TLB2, LTN170CT10
    My question:
    Will the newer lcd's work as a replacement for my older one?
    Anyone with the technical knowledge on this please reply.
    Thank you

    Another option:
    This site states the: LP171WE2-TL-03 is interchangeable with the LP171WE2-TL-A1.

  • Cant upgrade Airport Extreme on Macbook Pro Core Duo to 802.11n

    I have an original Macbook Pro Core Duo, purchased not long after Apple's announcement of "Bootcamp", and it has a "Wireless Network Adapter (802.11 a/b/g).
    From what I can tell from various documentation around the web, this should be upgradable to 802.11n with Apple's 802.11n Enabling software, however it tells me that the hardware is not compatible.
    If anyone can suggest what I am doing wrong, or whether I miss out, that would be good.
    Also, assuming it can not be upgraded, will running my local Airport network in "802.11n 5GHz 802.11a compatible mode" affect the speed of my other 802.11n devices on the network?
    Thanks.

    So you're basically saying 'Link Speed' shows the current connection? If so, the problem resolved itself. Sorry, my bad. Thanks anyways.
    (My Time Capsule hasn't arrived yet. I'm currently using an older version of Airport Express.)
    Another thing. When I asked at the local Apple Center for the 802.11n card, they told me, the card itself is not sold separately and even if so, it could not be exchanged, since it's unremovably attached to the logic board. Why do they tell the customers something like that? I mean, if Apple doesn't want the users to make changes like that, fine. Then they should say so. But why make up stories in order to dissuade people from their ideas? Is that common policy?

  • Ram limit in macbook pro core duo

    hi
    I was wondering what the limit of the macbook pro core duo is. I know it says 2 gb but has anyone tried a 2gb chip + 1gb chip? I also know the core2's can do 3gigs.
    I have had laptops that thave worked with way more than the specs said. My pismo's limit according to apple was 512mb ram I have had 1GB in that for many years. I think the 512 mb chip was the larges one at the time the computer was released so thats what was reported. is it the same thing with the first generation macbook pro's?
    thanks
    t

    According to Apple's specs the limit for the MBP CoreDuo is 2 GBs. The limit of the Core2Duo is 4 GBs although only 3 GBs is user accessible.
    The spec limit for the Pismo is 1 GB (512 MB per slot.) When new models are released sometimes there isn't RAM available to suit the limit of the model, so Apple can only certify a max based on what's currently available. You will find this is true of many older Mac models such as the Pismo.

  • MacBook Pro Core Duo 1.83 GHz fans (0 rpm)

    Working on a friends macbook pro core duo 1.83GHz 1,1 - It’s been shutting down intermittently; he’s been using a laptop cooler and it helped some. I installed iStat Pro and  SMC Fan Control and neither the left or right fan are spinning (0 rpm). I figure dust bunnies preventing fans from turning; took the top case apart and much to my surprise it looks as though the fans never spun. Ever! Not a speck of dust inside either one. I powered it up and neither even tries to spin; trying to jump start them with a push does nothing. All connectors look solid, nothing burnt.
    Any suggestions other than new logic board?

    Depends. Are the fans simply not working? Are they connected to the motherboard? Is the motherboard not working? Have you tried
    Intel-based Macs: Resetting the System Management Controller (SMC). There may be any number of explanations none of which you can know without taking it in for repair unless you have the repair equipment and know-how.

  • My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced.

    My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced. Is it internal battery for both, new logic board required, bad hard drive, or bad RAM?
    Help.

    Run an Apple Hardware Test using the original installation disk that has the AHT instructions on it.
    Try SMC and PRAM resets:

    It is possible that you may need a new PRAM battery.

  • Macbook Pro Core Duo Battery Exchange

    Hey All,
    I would like to ask a question. I have a Macbook Pro Core Duo, the 1,1 model of 2006. I recently found out, due to some issues i had with the battery a long time now, that its battery is part of an exchange program initiated late 2006. I found online that the serial number of the battery matches (ends with U7SC). However, i cannot find the website and the link i find is dead (404 error). Do you think that i can still go to an Apple Store and request a replacement? I know its a long time, but there is still a replcement program for the 1st generation iPod Nano, so it doesnt seem unreasonable to me. Thanks.

    The original program provided a reasonable time period in which you were to apply for a replacement and return the defective battery. As I recall it was not an open ended program, but you can always ask. The worst that can happen is they say, "No." In any event, any battery you had from that far back would no longer be functioning today, anyway.

  • Macbook Pro Core Duo froze and now boots into grey screen

    I was using my macbook pro (core duo) and just had a few apps open when it froze. I could still use my mouse but nothing else was working including force quit.
    When I restarted my computer, it did the spinning wheel and apple screen and then went straight from that to a grey screen, to never come back again. Sometimes it flashes to black before entering the grey screen.
    I did applejack and it finished with no errors...
    I booted with the command option p and r.
    I tried verbose and it gets past that and then gets stuck again at the grey screen.
    Safemode boots and works fine (except my airport isn't detected) and probably some other things don't work.
    I searched through other problems but couldn't find one that fit these specifications.
    Any help would be graciously appreciated.

    If safe boot works then it is probably a startupitem, launchagent, or launchdaemon that may be failing.  Look in your /Library/LaunchAgents, /Library/LaunchDaemons, and /Library/StartupItems.  All these are suppressed in a save boot.  You could start experimenting by removing all you see in those.  Or if you have some hunch of what may be a possible culprit delete that. Or one at a time.  Whatever.
    When I say delete I mean just temporarily remove them.  Observe ownership and permissions when putting them back.
    Note, I don't know why any of those items would suddenly start to fail just because you machine went south.  Perhaps some plist or other data got corrupted.
