I was upgrading the memory, SSD and optical drive (modded a blu-ray drive with the original upper shell from the SuperDrive) in a MacBook 2010 White Polycarbonate a1342 when I realized that one of the headers was...gone.

It turns out I may have accidentially broken it off, I think. So I took the cable and taped it somewhere else for the meantime.

The hader I think I have broken off is in the corner between the battery and optical drive. There are two very flat, slim headers with cables coming from - seemingly - the battery part, and they both plug in there. I somehow broke the other header, whilst not having even touched it after putting the plug back in (and it took me forever to do this with my fingers...). But when I was leaning back, I noticed that the bottom cable was loose again and when I tried to re-insert it, the corresponding header for it seemed to have disappeared.

I tried to find out what header it was, but unfortunately, all that shows up is the "Power on Pads" related topics and pinouts, with the MagSafe adapter included. But it does not tell me what header is on there, and if it is important or not.

After putting it together, I booted the laptop and it seemingly had no errors turning on. True, I have no OS on there right now but it still seems to be fine. The optical drive also seems to be powered and lets me insert stuff into it.

What do you think the broken header is, and how can I find it out? The cable seems to have two pins, whilst the other looks like having three. The 2-pin one has no socket anymore.

EDIT: I shared these pictures on Discord as I tried to get some additional help.

The broken header appears to be the right speaker connector (or the sleep LED connector).

Comparing it with the "left side" (and considering the two cables only) I tend to the speaker connector. The accompanying text is not very precise.

  • So either I have no sound, or no sleep LED (which ironically was rather annoying to me...so having it not work, is not that much of a bad thing). Thank you very much! If I really broke the speaker, I may have to seek further advice. Soldering might be an option since the pads are technically there...But I am visually impaired, so sodering is not exactly my forte. Thank you very much for the answer! :) Dec 11, 2019 at 23:48
  • @IngwiePhoenix I don't know whether the startup chime uses an extra speaker (I think so) but in case you hear a (pseudo-)stereo startup chime, then it's the sleep LED which is broken/missing... ;-)
