I've had a *similar* problem, after taking the back off a few times (MBP 2009) the screws nearly go back in, but just annoyingly not quite. I'm loathe to try it again too many times, it seems to be getting worse, but someone above's idea of trying the screws without the back on seems like an excellent idea. They just stick out about a mm or so.

It looks like a couple of other people have had similar problems too, it's just annoying as they are a bit scratchy when sticking out.

I'll finish up by saying that I'm an idiot too, we probably all are, so can we just all be friends and be nice to each other? Yeah? Lovely. Sheesh, your advice was pretty friendly I thought! Anyway, I'll have a look at mine and see if I can get anything from it. :D

I had a few screws that would not go all the way in. Seems there was some residual lock tighter that prevented it but this probably isn't your issue.
 
Hello All,

I have just upgraded to 8gb in my macbook pro early 2011 model. I am kind of having the same issue. When I took cover off, i matched it up on towel where i took screws off. issue is one of the longer ones on the top by the hinge, the middle long one will not go in all the way there was some blue stuff on the end of screw.

Appreciate the help,

The blue stuff is normal, that helps it stay in from the factory. Just make sure that it's going in straight, the long ones should be the top right three holes across the top (with the computer flipped over looking at it from the bottom).

Yep its the top 3 and its the one in middle that isn't going in all the way and I don't want to scratch my table since its not flush with cover like all the rest of them.

Anything I am missing or that you can do to help?

My theory is that when you removed the screws, breaking the Loctite's (the blue stuff) hold on them, it left some of the Loctite in the screw hole preventing the screw from being driven all the way back in.

Pretty bad theory. It's not a hardening locktite.

My theory is that the screws are cross-threaded. Some jobs are not necessarily best done by some users.

I will admit that I don't have any experience here so maybe I'm talking out of my a**. Have you looked at Loctite's info on the blue Loctite? Sounds to me like it hardens. From their website:

Cleanup

Clean adhesive residue immediately with a damp cloth. Cured product can be removed with a combination of soaking in methylene chloride and mechanical abrasion such as a wire brush.

For disassembly, shear with standard hand tools and remove with methylene chloride. In rare instances where hand tools do not work because of excessive engagement length, apply localized heat to nut or bolt to approximately 482°F (250°C). Disassemble while hot.​
 
wiggle the screws until they slide in then if you are sure they are in the right position. i mean seriously, you had to post a thread on this subject and thought maybe people who cant see this problem are going to believe that I am putting the screws in the right place?!?!?!

common sense after reading says they are either wrong, or just need a little convincing. like a big fn' hammer.

take it a genius or a mechanic and never take apart your computer again.

if your still not happy post some pictures so we can all agree or disagree without starting a pointless argument.

Sometimes screwing while pushing helps.

lol

this thread is full of "thats what she said" worthy comments. great post.
 
ok so how do i post a video or pics? that being said the screws are in the right holes. the locktite theory could be correct. its pretty much in all the way but the longer ones aren't quite flush. i have taken apart lots of pc's and laptops and this has never happened.

Either the threads in the case were stripped during the first install by Apple, or someone else took the cover off and then stripped the threads upon reinstallation or... you stripped the threads when you reinstalled the cover.


Another vote here for stripped threads.

I know this question was posted a few days back, but since nobody answered it, I will give it a shot.

While loctite blue does harden, it doesn't get that hard, and is easily removable with hand tools, unlike loctite red.

But more to the point, the blue material on the screws is not loctite blue. It would be closer to loctite 222sm, which is a low strength thread locker, and is particularly suitable for applications such as adjustment of set screws, and small diameter screws. But that would be assuming it as (a) thread locker at all, and (b) loctite brand.

Chances are, it is neither. More likely it is not a thread locking product, but rather an anti-galling coating. It is a plastic like substance that acts as a lubricant during assembly, while threading screws or bolts. As a side effect, it also takes up space on the threads acting as a light duty thread locker (which is why I mention it is closer to loctite 222sm.) The blue color is usually used on small screws.

post a video on a video site like youtube and provide the link. but dont make it a long useless video

some help here
 
The screws are different lengths. You have the wrong screws in the wrong holes...
 
This may seem silly, but when I replaced the RAM in my new 15" (upgrade from the first 2006 MBP!) I put it upside down on the table to take the screws out, but then forgot I had flipped the computer around when popping off the bottom. a quick 180 turn and I was fine....
 
Thanks for the help before I even needed it

I just put in more memory and couldn't get any of the screws back in (just like this user). Staring at the picture someone posted midway down the first page, I realized that I had put the front of the computer facing me to replace the memory, but I had the back facing me when I removed the screws. A quick 180 did the trick. :)
 
This is quite an old thread, but I had a similar issue last night and was trying to figure out what was going on.

All screws screwed in fine, aside for the last one which would not go all the way in. What I did to remedy this was to gradually screw in all of the screws together. I assume this issue arose from the final screw not lining up properly after the others had been screwed in.
