This is for my friend, who has been having some computer troubles. Already it has been sent in to the shop because of some problems, but just the other day something happened:

 

I sent a video link my friend asked for, and it contains a lot of popups that can be easily clicked away. On my own computer, ti works fun, but on that of my friend, a message popped up, saying that the computer had to restart. Following this, the computer can not start up, and instead beeps three times, repeatedly. I've looked around to see what information I could find, and apparently this means that there are "no good (RAM) banks".

I'd like to help my friend fix this issue, but I also hope it wasn't my link that did this. More than likely it's just a conincidence. THe computer has had some troubles before after all.

 

I'm looking forward to responses; this is rather urgent.

 

Thank you very much.

    Possibly the RAM is not seated quite right - maybe because of the recent service.

     

    MAYBE, it is as simple as reseating the RAM.

     

    Owner's manual and probably online stuff will give instructions.

    The message to restart is a kernel panic, which is usually, but not always, caused by a hardware issue.

     

    The three beeps, as you've found, means there is a memory problem. You can try reseating the memory (pull it out and put it back in) to see if that fixes the problem. If that doesn't fix it, try restarting with one or the other memory cards installed, as the issue could be a memory card that's gone bad. The next step would be to get some known good memory to substitute for the existing memory. If that fails, then it's likely a logic board issue.

    If it's that new, it's still under warranty.

    The computer can be opened and the RAM reseated very simply by its owner, using instructions printed in the user guide that came with it. Removing and reinserting RAM will not void the warranty.

    You can find and download  the manual for your machine here:

    If you don't have the necessary screwdriver, don't try to sunstitute anything else for it. Wait until you can buy the right one.

    Hello All,

     

    I had this issue this morning as well.  Although there were muliple different variables in my situation, I was able to resolve this for a client this morning.

     

    I found that said MacBook Pro could not read 16 GB (2 x 8GB) RAM, and had to attempt to switch it out for a lower amount.  I then tried 4 GB (2 x 2 GB), reset the PRAM, shutdown, reset the PRAM again, took out the OSX installer disc, put it back in, etc.

     

    Best Practice:

    1) Check, re-seat, or insert proper amount of RAM.

    2) Reset the PRAM (Command+Option+P+R)

    3) Take out any CDs or DVDs

    4) (Optional) Reset the PRAM again

    5) (Optional) Cross your fingers and wait...  BE PATIENT!

     

    Otherwise, follow the outlined help from "BGreg" and resolve this issue as possible.

     

    All the best,

    -- Morris

    Just thought I'd mention that I experienced the 3 beeps issue when connecting a portable USB-powered drive to my MacBook Pro and attempting to boot from it. Has nothing at all to do with RAM, because the machine boots normally when I disconnect the drive. This obviously shows that the 3 beep error is not related to RAM per se, but to a startup condition which fails.

     

    It would, of course, be nice if Apple had a KB article which described the conditions under which this error might occur, but apparently it does not.
