Yellow burn marks coming up from heat vents?!?! Ahhh!

Hey ya'll
Just a quick question, the bottom part of my screen, where it connects to the main section of the mac book pro (the hinge) appears to have gone yellow, a burny way that scares me. Am I right to be scared?
In a vaguely related matter, the Sims appears to be having the odd graphics glitch when loading at the moment, perhaps the whole thing is just on big graphics card overheat?
Let me know!
Cheers
Matty

Do you have any programs installed that tell you the temperature and fan speeds on your MBP?
If not, you could download something like
iStat Pro
http://www.apple.com/downloads/dashboard/status/istatpro.html
It tells you the temps, speeds of fans and other things happening on the MBP. There is a specific fan control download but I can't think of the name right now. I would defenitaly get that looked at though.

  • Burn marks on ipad

    My ipad has burn marks which are from the magnetic strip, ive read that it could be rust from the smart cover but there are actual burns on my ipad, my question is will apple replace my ipad with a new one? Or will they just give me a refurb? Hopefully they will give me a new ipad air  

    Well, you would have to take it to Apple as only they can evaluate the issue and decide if it falls under the warranty or not.
    Regardless, no you will not get a new iPad Air.  Whatever replacement you may or may not get, it will be an identical device to what you have now.  And odds are that yes, it will be a refurbished service unit as you do not usually get a new device in exchange for your used device, under warranty replacement or out of warranty replacement.

  • Burning Smell, then Smoke from Vent

    So yesterday I was playing this game that my friend convinced me to buy on the Steam Store called "The Binding of Isaac", when I smelled a burning smell. I went downstairs to the kitchen and nothing seemed wrong, so I ignored it thinking it was something outside and went back to the game.
    A few minutes later I smelled it again and looked up to see a puff of white smoke coming from the vent of my iMac. I quickly unplugged it and let it be for a few hours.
    I've been using it very cautiously since yesterday, but everything seems normal. I'm super paranoid now. >.<
    What could have caused it? Our air was off at the time and it was somewhat hot, so could it have been the game (Which I don't think is really that intesive... It's 2D.) + the temperature of the room?
    And mainly, what should I do about it? Continue with normal use? Take it in to get it checked out? (I'd rather not do that as the nearest Apple Store is an hour away) I just got the iMac in December and it's the first Mac I've ever owned, I rather not say goodbye to it so soon.

    A strong possibility is that one or more electrolytic capictors blew out.  What you saw may have been steam from the cap dying.  It may continue to work but there has been some damage that should be repaired so that one problem does not cascade into multiple problems.
    Check your warranty status and if you did not purchase AppleCare when you bought the computer you must buy it while your normal warranty is still in effect.  That is one year from the date or purchase.  AppleCare provides fopr three years total of coverage. Otherwise you only have the one year coverage on your hardware.
    Seven or eight years ago a supplier of these style caps changed their electrolyte formula.  The caps ran okay for a couple of years but then started blowing out,  When they did any numbver of problems would appear from bad video to shutting down and not powering up.  The last series of the old Power PC chipped iMacs suffered from this capacitor plague.  The problem has since been corrected but, like anything, it is possible that a cap in your system may have slide by quality control and now you see the results.
    You may want to call AppleCare and see if on-site repair coverage is available for your system.  Look at the Apple Support web page to send an Express Lane case with AppleCare to schedule getting a call from AppleCare.  The number is 800-APL-CARE or the web site is: http://www.apple.com/support/contact/

  • Got a funny smell earlier and burn marks on my hinge (adapter UK/US)

    Hi Everyone
    Had a bit of a scare earlier at work! Could smell burning in the office, with all the equipment we have it could of been anything but it did seem to stop once I shut down. I don't use the battery anymore as it died a couple of years ago and generally use the mac with only the magsafe adapter. Up and running now and cannot smell the burning anymore. But I have noticed that I have burn marks on my hinge where the vents are (http://twitpic.com/ldehc sorry not a very good pic).
    The temperature of my mac gets very hot and when I first restarted they were (Fahrenheit)

    This obviously gets worse the longer I use the machine.
    Now I am currently holding out on buying a new laptop till I move to the States in December. Obviously it will be cheaper and fit the appropriate plugs (not 3 pin). But I need a computer for work, so if need be I might have to splash out the extra and buy one here. If I do will I need to buy a new magsafe adapter or can I just use one of those converters (3 pin to 2 pin)?
    So my question is really
    Do those stats (temps/fans) seem weird or too high for an hours use?
    Does the burnt marks look serious or have others noticed this from a 4/5 year old MBP?
    Cheers and thanks for any responses
    Rob

    To me that looks more like a liquid stain, like
    something liquid got under your MBP and dried up.
    Doesn't look burned at all. Or another thought is the
    wax finish did dry up from the heat. A burn mark
    would look like burned wood. YOu shouls purchase a
    Podium Pad anyway for the sake of your table, but it
    looks a good waxing would fix that.

    Are you kidding? I really hope you are, because that has to be the most uneducated post I have ever heard. That melted the lacquer on the top of the table, meaning the case would have to be at or around the boiling point of water, the temperature that lacquer chips are melted at. Wax would do NOTHING.

  • Ipad mini burn mark

    II've had my ipad mini for just under a year it still has warranty for about 3 weeks. just recently i was on the internet and this logo just appeared burnt on the screen. When I went on the home it still stayed on. I don't know If I should go to the apple shop or not like I said it just recently happened.

    I know this is an old thread, but its one of the first that comes up on google when you search for this.
    I can tell you quite certainly that this is not rust.  I have identical damage to my ipad and am quite certain it is a burn mark.  I have worked professionally on various electronics for over 10 years and have seen damage similar to this quite often.  The key to identifying it as a burn over a rust stain is the accompanying damage present in the aluminum.  There is very minor pitting present in the aluminum which you would not see if this was simply a stain.
    Also on the smart cover, the magnet is covered in some sort of plastic.  On my damage it is centered on this plastic strip and not near the edge.
    I plan on taking my iPad to the Apple store as soon as I return home.  This is not discoloration and it is not rust.  This is a burn mark from either heat or arcing.  It is possible the wifi antenna induces a small amount of current flow in the case and there is some sort of interaction with the magnet which causes it to arc (and ultimately burn) between the case and the magnet of the cover.

  • Burn mark on iPad 2?

    I'm seeing burn mark on my iPad 2 and smart cover (magnetic strip).  Both the markings' location matched exactly when the smart cover is attached to the iPad.

  • Burn mark on charger

    My charger has stopped working. I'm not familiar with the correct terminology. On the power adapter (white square), there is a cord sticking out which you use to connect to your macbook to charge it. Where the cord and the power adapter meet, there seems to be a burn mark and the plastic has holes in it.
    I'm not using the charger anymore, for fear of damaging my macbook. I'm going to buy a new one from Best Buy probably. I think I should get the same model, 60W MagSafe.
    I assume the burn mark came from over heating. What do you guys do to prevent this from happening?

    Hi Cinday,
    You may want to look at this Apple article about what you have experienced. See the If you see a spark section.
    Best of luck.

  • I am missing masters in aperture , getting an yellow  exclamation mark , but still getting a preview of those pics .how to create a master .i have done rebuilding , repair , but still same?..please help

    missing masters in aperture , getting an yellow  exclamation mark ,

    Q: Is there a way to place an image at 100% without having to do that extra resizing step?
    I think here you want your images to fit in the full page size frame automatically. For this you can try the follwoing steps:
    1. Create a new doc
    2. Goto Object menu and choose Frame fitting options
    3. Select Autofit and from Fitting drowdown, select "Fit content to frame". Refer the screenshot below:
    After this you images should automatically fit in the entire page placeholder frames. Please let me know if this does not work or if the problem you are facing is different and I did not understand your problem correctly.

  • Ideapad S400u - Noise coming out from the headphone jack

    I also have this annoying noise coming out from my headphone.
    It happens while the notebook is charging/plugged.
    Could anyone help me?
    My lenovo is Ideapad S400u - Windowns 8.1 - 64 bits.
    Thank you,

    Igor,
    Welcome to the forum!
    Can you describe this noise?  Is it coming from the area around the headphone port?  If you plug headphones into the port, does the noise go away or change?   Is the outlet you are using for charging grounded?
    Thanks

  • Not coming out from DB Tools Execute Query

    When I am removing my Ethernet connection and again connecting[for server client communication ], then sometimes the DB Tools Execute Query.vi function stucked inside and not coming outside from this function for infinite duration.
    How can I come out side this function when some network issue will come?
    When network connection is OK then that time there is no any problem, it actually occurs when network connection lost during the program ececution.

    It's hard to say what the problem is. One recomendation would be to drop usage of the database connectivity toolkit as it adds a lot of complexity and limits your options for troubleshooting problems. There is an alternative here. Read the discussion and download the drivers...
    Also, what kind of database are you connecting to?

  • Does anyone know why I am getting a yellow question mark by my AS3 .swf?

    I developed a few Actionscript 3 animations in CS Flash 5 to use in Cp5.  Instead of the green ball icon in the upper right corner of the animation, I am getting a yellow question mark like I did when with my Actionscript 2 .swfs.  The reason I created new ones in AS3 was to avoid any conflict.  Hmmm
    The new ones I am trying to use are Moving Red Circle, Moving Red Rectangle, and Moving Exclamation Point.  The Green Ball items are from Cp5 Gallery.
    Thanks

    Ah...that explains why you would be seeing these icons.
    When Captivate's library opens, it goes through and checks the locations of the objects in the library to see if it still can connect to the source file locations.
    I would say the way to get around this would be to have the path to all source files replicated on each machine you work on.  So if you set up a C:/Projects directory with exactly the same folder structure on each PC you use, the path to source files should remain the same.  But I think trying to keep all the files in three machines always synced up will be more trouble than it's worth, personally.

    Okay... well at least its not the WLC code or AP tht is an issue.  RLDP whould only be used on monitor mode access points, When used with access points that serve clients, the AP when detecting a rogue, will drop all associated clients.  The AP's will do rogue detection anyways, so no need enable RLDP.

  • Yellow exclamation mark in references: What does it mean

    In my c# project, i have references to c++/cli and native c++ projects under "references". (i need to have them there, in order to be able to use msbuild on my solution from the command line.). all of these projects have yellow exclamation marks overlayed
    to the "reference" symbol. (vs 2010). i can't find any explanation what these symbols are supposed to tell me.
    any ideas ?

    Hi Thomas,
    I think this behavior is a warning to user that the native dll referenced by C# project is not supported there.
    And I cannot say if it is by design or just a bug, would you mind sharing the connect link here, so that others could see and vote on it?
    In addition, for msbuild issue, you may try MSbuild forum for better suggestions/workaround.
    Thanks for understanding.
