  • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

  • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

How much weight can I save by removing the optical drive?

gunes314, · Reply

Also wondering how much weight I'd save by just removing. My drive is broken for ages, but I have not needed it in ages. The HD was already replaced by a cheap SSD (second best thing after upgrading to 8GB), so I'd appreciate losing some weight. I mean, the computer. Although I could lose some too... erm... well, anyway, I guess the lack of the DVD would not interfere with anything, right? Opinions?

I'm thinking you'd probably be OK losing the DVD drive without a problem. Just make sure the optical drive cable is secured or you might hear it rattling in there from time-to-time.

Hey guys,

this website is amazing. I read it to guide me on fixing my mac book pro, but on the video, the girl gives a wrong information.. She says that is not possible replace just the keyboard... But I managed to replace only my keyboard. It is boring because I have to remove approximately 70 screws but it is possible. Thanks a lot! You guys helped me save about US$300 thats because in Brazil some technicians would charge me with that amount!

I posted some pictures on your facebook page..

Tip: Use one of those weekday pill holders to have a cheep way to store screws you remove and each day of the week can be for different sizes or parts. It has been handy to have (much less expensive than the magnetic mat.

Great tutorial. I found that using a Phillips #0 in lieu of the #00 worked much better.

I tried the PH #00 for the 10 screws that hold the bottom case and it's too big, instead PH #000 works perfectly. Are you sure this screws are #00?

The likely problem with your wifi is not the card but the antenna leads that go into the plastic clutch

. Ifixit don't have a guide to change this as it it includes the isight camera so the screen has to be disassembled which is fairly hard

I got round it by using the camera cable from the old set and cutting off the new one

Is this step of removing the battery connector required?

manodh, · Reply

yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

khull,

This step is not really required. Apple does not recommend it.

My Battery does not get recognized after i disconnected it, screw this site!

Diego Hernandes,

Rather than be careful of the corners of the connector i would say don't use the spudger anywhere near the corners. While the corner looks like the obvious place to begin to pry it up from, it will break. Levering from the sides as the instructions suggest works well.

wonder why apple does not recommend it?!

Peter, · Reply

I would recommend it, one careless short and the whole board is dead......

John, · Reply

simply remove the battery rather than disconnecting the cable

Don't know what the deal is with the battery, but this IS a necessary step to keep from frying the logic Board if you accidentally touch something and short it out. I did this step every time during my troubleshooting and The battery was ALWAYS recognized by the system the next time I turned the MBP on. So be safe and don't fry your logic board in the process...

What are the changes of it broke when i bend it?, after i disconect it does not work anymore

Diego Hernandes, · Reply

The guide worked perfectly, as it has in the past (our family has three Mid-2012 Macbook Pros that have been separately upgraded with RAM and SSD).

The PH00 screwdriver fit perfectly.

One note on getting the screws to seat easily and thread perfectly...always turn them gently a couple turns to the left (CCW or Anti-Clockwise) until you hear a small click. That's where the threads will grab. Works with any screw, but when threads are fine, this will help ensure that the screw is at the correct angle and will grab and seat perfectly.

Great guides. Thanks!

Got RAM in but only one slot is working and now I can't remove! The RAM won't pop up like before and tabs don't seem to do anything. Please advise.

Tri-wings are quite sensitive to which size driver to use. I found Pro'sKit brand size 0 seems to fit these very well.

James, · Reply

can i just take out my dead battery without replacing it,

and solely run my mbp on power supply to save weight and money?
