Battery & Strange Burn marks!

I need help yet again! I'm really not having any luck with my MBP and it's only 7 months old!
Last night I was working away on my MBP and it was connected to the mains. I wanted to move rooms so left the computer on, and unplugged the power, but the computer just shut down! Strange because the battery was almost full and charging.
It wouldn't switch on without it plugged into the mains. I removed the battery and plug and did the Power reset thing. This worked. And it was working fine, until today it did it again but this time the Power reset won't work. So I removed the battery and noticed a line of small burn like holes along the top where the processor is. I've taken the battery out before and never noticed this.
They look like screw holes, but tarnished and brown, almost rusty, and they're not evenly spread across. I've taken a couple of pictures on my mobile and you can get the idea of what they're are like.
Are they normal? I've never noticed them! What has happened? It did crash the other day but it's working ok.
If not the spacebar, powerbutton or crashed OSX it's the battery! What else can possibly go wrong!

Hi!
Thanks for the info. I checked the links you gave me and it lists symptoms for the required battery recall. However my symptoms don't seem to be covered in its list. However I was going to fill out the form anyway to send off my battery's serial number and computer serial number to Apple to see if my battery qualified under the recall. However under the "How to find the Serial Number" section I've noticed that where my MBP serial number should be printed, as shown in their diagram, is where the mysterious marks are! So it seems that the marks might by where the label should be printed! Therefore my computer's serial number isn't on my computer! Therefore I can't send off for a new battery from Apple. Should I be worried?

  • 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

    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 Marks on the bottom of my mac

    my mac seems to have overheated and now there are some serious burn marks on the bottom. what can i do to help it cool down?

    Hey,
    If you have burn marks you have some pretty serious issues. I'd contact Apple. I wouldn't be looking for a Band-Aid® when you need a tourniquet

  • Help!  Has anyone ever seen a strange question mark  in their folders?

    please help, for some reason there is a strange question mark on the top bar of every folder that i open, to the left of the search box. It's quite large and slightly darker than the folder window color around the edge, and when I click it it pops up a new window that says item cannot be found. It has never been there before, what is it and where did it come from, is this a virus? S.O.S.
    powerbook G4 17"   Mac OS X (10.4.6)  

    Control-click on it and choose Remove Item from the menu which appears. The Finder toolbar allows files and folders to be dropped into it; when the Finder can't find one of these, it displays the question mark icon. It is not a virus.

  • Imac has a burn mark on the logic board

    i have a imac emc2266
    i recently came across a imac alumium 20 inch and the guy said it doesnt boot and doesnt chime
    i have tried every setting and every test still nothing.T
    The fans spin and the computer tries to boot
    led 1and 2 are on but the logicboard doesnt have a third led
    the computer will run a mouse but the keyboard will not power
    i checked the logicboard it has a small burn mark
    next to the audioboard

    I doubt any of those have burn marks. something on that board has fried causing the burn mark. you could find the failed part and try to replace it but you never know what else failed at the same time or failed because of the fried part.

  • Battery Big Question Mark Symbol

    My pre plus has suddenly developed a battery big question mark symbol. Any advice?
    Post relates to: Pre Plus p100ueu (02)

    Battery symbol with a question mark indicates no battery present in the device. You can try cleaning the battery contacts with a pencil eraser, or replacing the battery. 

  • Strange greyed mark on screen?

    Hi,
    I have just noticed a strange grey mark on my screen (I think it is similar to the ghost mark questions some people have posted).
    It only shows up when the screen has a dark colour on it, but is only visible with the backlight on, and seems to disappear when I dim the brightness al the way down, see pics:

  • 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.

    I know this is an old thread, but its one of the first that comes up on google when you search for this.

  • 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.

  • 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.

  • Strange question mark error while opening pdf files in adobereader from SAP

    Hi Gurus
    We are having a strange intermittent problem with Adobe Reader. When we try to open PDF files from SAP Frontend we get an error pop-up. The pop-up does not have any text. The title of the pop-up has "Adobe Reader". There is a blue question mark and an OK button.
    This issue occurs few times a day
    This issue does not occur in Windows XP.
    Since past few weeks, we have been trying to find some error/warning/atleast some text in log files of SAP, OS, Adobe Reader, Registry entries, Event Viewer. So far, we have not found anything.
    SAP is not able to help as this issue occurs intermittently and said when they tried, the issue did not occur. They made two attempts and in each attempt they tried 10 times to reproduce the issue. This issue occurs intermittently.
    Environment
    SAP R/3 4.7 EE SAP_Basis 620 Support Package 61
    Windows Vista Enterprise
    Adobe Reader 9.0 and Adobe Reader 9.1 (tried with both versions)
    SAPGUI 710 Patch 12 (latest patch). It also occured in Patch 11. 
    Please suggest
    Thank you
    Pavan

    Thank you for the quick reply.
    We tried many notes from Service Market Place. Also, Windows Team is in contact with Adobe.
    As per Adobe's suggestions, we tried changing preferences of Adobe Reader. We think it might be a problem with SAP Frontend.
    Present status - Issue still exists. nothing works.
    Thank you

  • HP TouchPad - Battery with question mark.

    HP TouchPad (16GB) WebOS/Cyanogen Mod daul boot.  When I turn on the TouchPad it boots to a screen with a white edged battery with a question mark in the middle.  When the charger is plugged in the home button or center button on the TouchPad lights up left and right.  I haven't been able to boot into the boot menu since this has been happening.  Could someone please tell me how to fix this?  I have read a forum on how to re-partition the TouchPad's drive to reinstall WebOS.  Here is the post here, http://www.souldevteam.net/blog/2012/07/24/fix-bricked-hp-touchpad-recovering-software-bricked-touch...
    Could someone tell me if this might help the problem or if there is another way?  Thanks.

    Sorry, HP doesn't support changing the OS on the touchpad.  
    Check out some of the touchpad threads over at http://www.webosnation.com .  They have one specifically for "Android on the TouchPad.
    The usual answers for this issue in webOS are: Check your charger brick - make sure the prongs haven't rotated out of the normal position; try another micro-USB cable; make sure you have power in the wall where the charger is inserted.

  • Boots to folder with exclamation mark or battery with exclamation mark

    recently purchased a used ipod 3g. i came with a dent in the uper left corner of the back of it. im not sure how old it is. it will (without ac pluged in) show the apple logo then turn off, when pluged in it will show either a battery with a exclamation mark,or a folder with an exclamation mark. when connected to windows it is recognized as there being a usb device there but it cannot determine what it is. when connected to a linux box (also have 4g ipod works fine on this box) it will nto even detect it. also when plgged it and booted you can hear the hard drive and it is rather loud. im guessing that the battery is old and dead and will not recharge (as i have seen no sign of it recharging) and the hard drive is dammaged. I have tried reseting, disk mode. both to no results please help for i dont want to pay to have it fixed.

    tingyster hello,
    Yeah, it could be 2 problems i.e. battery and hard disk, but it could be some thing wrong and stop your iPod to get charge. So please plug your iPod have a charge with the AC charger for few hours. (Do a reset before your plug it the charger). Then find a Mac computer, put your iPod in disk mode and connect it with a Mac compter, do a Restore there, if you can able to finish the restore process then connect it back with your PC, and redo the Restore with your PC.

  • My old iPhone 3GS battery just burned and cracked open

    This morning i found my old iPhone 3GS on the sofa with the battery burned and the case cracked open. I am happy that the sofa did not burn, too.
    It wasn't connected to the charger. The battery was possibly empty. It lied there already for a while.
    Do you know if there's a warranty plan is such extraordinarily cases? I know the phone's old. But it shouldn't start to burn on the sofa.

    Apple's hotline robot first told me i had to pay 35 € in advance in order to tell them about the problem. I tried it anyway. The guy on the phone told me that in this case they'll talk to me without Apple Care. Unfortunately they only proposed a repair option for 160 €.
    He couldn't tell me what would have happened when the phone had burned the sofa. Anyway i'll now will give my old iPhones to recycling and not display them in the shelf. Poor old first gen iPhone.
