This Guide is here to help you upgrade your Late 2008 2.0Ghz Aluminum Unibody Macbook to have a Backlit keyboard! (without buying an entire new topcase!) Keyboards can be purchased off ebay for less than $75.

Запчасти

No parts specified.

  1. Some 2.0 GHz A1278 MacBook Unibody logic boards do not have the necessary socket installed to accept the keyboard backlight ribbon cable attached to the upper case. The first and second pictures show logic boards with and without the socket installed, respectively. If your logic board does not have the backlight ribbon cable socket installed, the keyboard will work but the keys will not light up. If your logic board does not have the socket installed to accept the keyboard backlight ribbon cable and you are installing a backlit upper case, simply tuck the keyboard backlight ribbon cable out of the way when you reinstall the logic board into the upper case.

The photos which show how to install the backlit aren't showing. Is there maybe another thread which shows them because I can't really figure it out .

The photos aren't failing to show up, there just aren't any photos - no one ever uploaded any, even though the text of the guide talks about the pictures. As you're doing the upgrade yourself though, snap some pictures, edit the steps here, and upload your pictures!

Taylor Arnicar -

just a question. Where exactly do I put the backlight? Because I have a black film, then a thick plastic sheet, then the metal. then the silicon layer with the components inside, and then the front black sheet, and above that you mount the keys. In between which layer do I put the backlight?

Kevin Zygmunt - Ответить

Remove black film and put your backlit

Clodoaldo Castro -

I realize that this guide is getting a bit old, but I bought just the backlight part off Ebay. It's essentially a black film with couple of leds, a clear plastic sheet and a black matte layer. It goes on top (if you look at the MB from the bottom, as in this guide) the metal layer. So it replaces the parts you remove in steps 32 and 33, after which you can start reassembling.
