Keyboard Lighting not working *photo added*

[Benwalker93]

Hi there,

I recently purchased a second hand late 2008 Macbook Pro. This being my first Macbook I didn't think to test the keyboard lighting upon purchase. I have updated to Mavericks. The f5 an f6 keys work and the graphic comes up on screen as if the lights are responding.
I did some researching and it's possible something may have been unplugged if the computers ram was changed and upgraded; is there a way to find out if the ram is standard or not? any suggestions to a fix or to test the hardware?

Regards

Ben

open the macbook and next to the ram is a ribbon ,that is the light for the keyboard, some people when the replace the ram, the ribbon can come unplug.

I went to remove the casing and there is a warranty sticker over one of the screws that need to be removed for access. Im unsure to it has been removed and re-stuck on. Should I just go ahead and remove the sticker to check?

 

[chrisperro]

do you have some kind of warranty with the macbook?
what is the reason of the sticker been there?
if not just remove the sticker and continue.

I confirmed with apple that the ram had been changed at some point and went ahead to open it up. Following this thread as a guide on the parts as I am new to this:
