Edit Step 3 Battery Connection  ¶ 

  • 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.

Edit Step 4  ¶

No, it does not void the warranty. More specifically: http://eshop.macsales.com/Search/display...

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.

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.

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.

The replacement cable comes without the sleep led attached. Thus you have to remove the flat cable of the sleep led from the socket of the old hd cable. Take your fingernail and lift the side of the socket opposite to the cable. It's really tiny! Afterwards insert the new cable and push gently on the part lifted up before.

Hi, I feel like this article is missing an important step at the end. How do I replace the new IR sensor/sleep LED with the old one that is still attached to the front hard drive bracket? I see Skyynet answered this but it is still nor clear. Pictures would be nice. Thanks!
