    • Remove the following ten screws:

    • Three 14.4 mm Phillips #00 screws

    • Three 3.5 mm Phillips #00 screws

    • Four 3.5 mm shouldered Phillips #00 screws

    • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don't go straight down).

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

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    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.

    Hello, where can I buy the screws I need in case I lose one of them?

    I have one stripped screw... How opening without drill it?! Any suggestions please?

    I also stripped a couple screws. I wasn’t able to open it up without drilling. After drilling the heads and removing the cover it was easy to hacksaw the tip and unscrew with a standard driver.

    My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

    A good Phillips 00 is your friend here. Also, when reinserting the screws, gently start anticlockwise and you wil feel a click at the start of the thread. This tells you you’re in the right place and less likely to cross-thread through force in the wrong place.

    I feel like these are 000 screws. Amazon sales describe them as such and my 000 screwdriver fits better

    Before ordering a new Trackpad remove the existing battery and try clicking the Trackpad. If it clicks OK with the battery out the source of problem is likely a swollen battery, which should to be replaced even if it still works to some degree. From the side of the battery you will likely see the soft part of the battery bulging beyond the hard case.

    That’s absolutely correct as I can testify. With the battery removed I also adjusted the T6 set screw that adjusts the sensitivity of the trackpad click, evidently someone had cranked mine down tighter than the factory setting.

    Le quatrième paragraphe dans les instructions en français n’est pas correct : ce ne sont pas les 2 petites vis, mais les 7 petites vis qui sont inclinées. Et les 3 grandes sont bien verticales.

    Tip: if you have a magnetic screw mat or similar, lay the macbook over the mat to make sure it catches any screws that may decide to fall of and hide under your table

When purchasing a new bottom panel, do any of the stickers or pads have to be transferred to the new part? How?

Matthew Parrott - Reply

This is the instructions on how to just remove the bottom cover to access other components. The part is sold here on iFixit for $99 and looks to include the rubber feet.

Where can I get a new backover?

Can i buy this bottom replacement piece here or is this instructions on how to do it?

itsRadioBiz - Reply

These are instruction on how to replace the cover as if it came with the screws and rubber feet. There are other tutorials on this site on replacing the rubber feet and they do sell the bottom casing (with the rubber feet) and screws here.

Guys, I respect you really. Your effort and hard work through all this years is trully remarkable. A R.T.R rulz! Shout out! Thanks for all guides, teardowns, for all that funky, cool stuff you’ve been disassembling and putting back together over and over again, and again. It is helpful. But this 99USD? What? For a 13 inch plate that’s been made of aluminium? Hm.. let me think…should i buy two plates of aluminium or a used, working Macbook? Wait a second. Maybe I can buy it for even less than this plates, cause the full price with shipping and fees would cost me somewhere around 270 USD. Great! All the best!
