Black screen after upgrading ram (macbook pro late 2007)

Dear Community,
I am willing to donate 100 USD to anyone who is willing/able to provide concrete resolution to this problem.
I am a professional freelance videoeditor and my job is currently stucked due to inability to boot my macbook pro again.
After upgrading the RAM of my MBP (late 2007 model, 17'' display, Intel 2.4GHz Dual Core processor), the screen went black and the system did not boot any more.
I tried to replace the orginal 2 x 1GB DDR2 533 CL=5 SODIMM (single rank) with 2  X 2GB DDR2 800 CL=6 SODIMM (dual ranks).
After the memory upgrade, the system was restarted, I heard a short beep, but the macbook showed a black screen instead of booting properly. The mainboard was powered, the fan was moving. I saw a green led turned on on the center of one side of the macbook.
I tried to mount the previuos 2 x 1GB DRAM SODIMMs, but nothing happened. The system keeps not booting even with the original memory.
I tried already several procedures suggested by the user manual, related to SMC Intel controller reset (with battery and without battery and charger), but those were not effective in restoring the normal operation of the macbook. The system keeps not booting with exactly similar issues (black screen, fan on, short beep after power-on, green LED on).
I also tried to swap the memory DIMMs into the memory sockets. I tried to use a different combination with 1 NEW 2GB and 1 OLD 1GB  DIMM. But the problem is still there with similar sympthoms.
DOES ANYONE HAVE ANY CLUE OF HOW TO SOLVE THIS?

My best guess is that you have fried the RAM with static electricity charged up in your body. According to OGELTHORPE a beep on startup is because of no RAM, if when installing you did not do it correctly, you could have fried the RAM, which then your mac will not recognize it. The same with the old RAM, if you tried to re-install it and didn't pull up your sleeve and rest your arm on the inside of the chassis, then it is fried, or if you didn't wear an ESD band and connect it to the the chassis, then it is fried.
Seen as though you can't startup your mac, I can't say to do an AHT, buy some new ram, and start with the lowest one you can, so its cheap for ya use a different company incase is that;) Crucial.com is really good, I got an 8gb upgrade from 2gb. Let me tell you, it's great!

  • Can i use an WD Scorpio Black 750GB in my Macbook pro late 2007 ver 3.1 ??

    Hi everybody
    Just wondering of I would run into problems installing an WD Scorpio Black 750GB in my Macbook pro late 2007 ver 3.1. 2.6Ghz.
    Already have 2 500GB installed in RAID but need more space and want to upgrade but someone told me that this MBP ver 3.1 only supports max 500GB drives......
    Is that true??
    Thanks

    If the hard drive is 9.5mm thick any SATA hard drive can be used.
    A few may require jumpers if they are higher than 1.5Gbps in data speed.
    Only 17" MacBook Pros of that generation could take 12.5mm thick drives.
    The capacity is not normally the limit anymore, it is the thickness and data path speeds that make a difference. Also your machine supports external SATA drives that are 3.5" with this adapter:
    http://eshop.macsales.com/item/Other%20World%20Computing/EXP34SATA2P1/
    These drives are faster than any internal, ethernet, or Firewire drives you can add to your machine.

  • Black Screen After Upgrading to Windows 8

    Hi
    I'm experiencing a black screen after upgrading a Dell N5050 B890 to Windows 8.
    Tried to refresh the installation but the problem persited. re-installed the Windows 8, the machine logged in successfully but the problem arose again after reboot.
    Urgent assistance needed 

    This problem is solved...
    I guess the problem is concerned with the display module controller in the BIOS which is having a slight compatibility issue with windows 8.
    This issue is solved by updating the BIOS of your Laptop/PC to the latest version. You can download the latest BIOS from the website of the Laptop company/Motherboard Company. 
    But for updating the BIOS, you have to start your computer/Laptop for at least one time in Normal Mode. So here are the steps to do so... 
    1) Boot the Laptop/PC.
    2) After the boot screen (The Circle Animation & Windows 8 logo), you will be presented by the lovely & awesome blank screen.
    3) Wait for 1 minute so that drivers load into the memory.
    4) Press the Power button of your laptop/PC for only a moment (Just Press and release it quickly. Don't hold. We don't want to shut down).
    5) This will force the laptop/PC to go into Sleep mode.
    6) When the laptop/PC goes in sleep, the laptop fan & other sounds will stop.
    7) After 4-5 seconds, press the power button again & release it quickly.
    8) Voilllaa!!! The laptop/PC starts & you are presented with the lock screen. Now..... Login! What are you waiting for! :P  
    This is not the permanent solution. It just lets you start you Laptop/PC.
    After updating the BIOS, I strongly suggest that you must download the latest graphics driver for your Computer/Laptop to avoid any further issues.

  • MacBook Pro Late 2007 Keyboard Cleaning

    I have a Macbook Pro Late 2007 with the older style keyboard and I really want to clean it because there are dust around the keys. I tried spraying compressed air but that only got me so far, so I was wondering is it a good idea to take the keys apart and clean it or is there a better way to do it? If the Apple Store has a service for this then I'd be grateful to bring my laptop in.

    I've taken off notebook keys to replace them - but never removed them all to clean them. I would be a bit nervous doing that as it's fairly easy to snap those caps. You can call the Apple Store to ask - or just make an appointment for a Genius Bar visit and see what they say they can or may do.
    Good luck,

  • What is the expected battery life for a battery in the MacBook Pro (Late 2007)?

    I purchased a replacement battery from an Apple Retailer for my son's 17" MacBook Pro (Late 2007) in December 2009. Last week, he gets a "service battery" message and the battery won't hold a charge. Is this the best we can expect in terms of battery life? It was supposed to be an Apple Battery.

    Has your son been calibrating the battery per the user manual schedule?  Has he been using the computer properly? According to the user manual it states in part:"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."
    MacBook Pro: Care, Use, and Safety Information
    "Do not place your MacBook Pro on your lap or other body surface for extended periods of time. Prolonged body contact can cause discomfort and potentially a burn."

  • Macbook pro late 2007 - Black screen in Lion

    I have a big problem with the new Lion install and updates, I install the soft all was ok untill this morning I turn on the laptopn and Black screen. I foun this message in errors:
    kernel extension info no kext loaded
    So I keep re boot and reload the system all day but I think in uninstall the Lion untill this is FIX. Any help will be good.
    Thanks in Advance.

    Just to add - I too have had this problem with my late 2007 Intel, Core 2 Duo MBP. Installed Lion, Restarted, black screen - several times. Apple Genius tested the graphics card for the global fault with the NVIDIA GeForce 8600M, but found it innocent. Can only put this down to Lion's Nvidia Drivers that are also causing problems with 2010 MBP's
    I have reinstalled SL from clone I made prior to Lion, and all is back to normal.

  • After upgrading my MacBook Pro memory to 8GB it no longer boots to an operating system.

    It is a MacBook Pro, mid June 2009 model and 13".
    I've followed the installation videos adequately and the orginal 2 x 2GB have been removed with the new 2 x 4GB successfully slotted in.
    It turns on and goes past the first Apple logo and the "ding", then lands on a light grey screen.
    A black arrow is active but there is no menu bar, icons or anything showing. 
    After a while the iTunes screen saver activates and I also noticed an alert from BusySync appear!
    Looking for an Apple genius to help me sort this one out!

    What I find interesting is this:
    A black arrow is active but there is no menu bar, icons or anything showing.
    After a while the iTunes screen saver activates and I also noticed an alert from BusySync appear!
    That suggesting that the computer is booting up - no other way to see the cursor screen saver. It would be strange to see this occur with bad memory but when returning the original RAM led to the same thing...
    I think it would be a good idea (start with whatever RAM you have installed now) to do a safe boot. Restart the computer holding the shift key until the grey Apple screen appears. Among other things this will force the system to perform a disk test and will erase cache files that sometimes cause problems. If the computer boots normally into Safe Mode you can then try booting normally again.

  • Spinning beach ball and black screen on my new macbook pro

    After great anticipation, I just updgraded to a new macbook pro from an ibook G4. For the most part, I am thrilled and applications open and web pages load quickly. Occassionally, though, I get spinning beach balls...with more frequency than I did with my ibook and in OS X native apps...such as Safari.
    Another problem I am having is in Front Row playing movie trailers: the screen goes black before the end of the trailer, but the audio continues.
    Any feedback would be greatly appreciated. Thanks!

    That is the automatic ambient light sensor doing it's thing.
    Depending on what machine you have, try turning the screen brightness all the way up. It will buttons on the top row, usually the F-1 for dimmer, F-2 for brighter
    Also you can go to sytem preferences>display and un check the automatically adjust brightness for ambient light.
    Hope this helps

  • Vram HD4000 before upgrade ram macbook pro

    Hello! Today I upgraded the ram in my macbook pro 15 "late 2012 (i7 2.3 ghz) bringing it to 16GB. Ram is Samsung 1600MHz. Vram I have noticed, however, that the HD4000 is not increased to 768MB (as it should be 4gb ram = 386mb vram, 8gb ram = 512mb vram; 16gb = 768MB vram.) What can I do about this "problem" does anyone know anything? (sitema is the mountain lion aggornato latest version).
    Thank you.

    The video memory (Vram) on any Intel integrated graphics is dynamic meaning that the amount allocated is dependant on  :
    The amount of total memory installed in the machine ie 2Mb, 4Mb etc
    The program being used and how graphically demanding it is.
    Thus the machine will allocate anything from 64 Mb upto 768Mb, you as the user can not normally change this.
    (This is the same for Windows machines with Intel graphics)
