MacBook 一体成型机身机型 A1278 光驱更换

I ruined my laptop because of this guide.

The step 6 says it's a connector that comes of (sub-woofer), mine was welded, I broke it, I cannot fix it.

i am frustrated, and I know I should only blame myself for following blindly that guide.

But at least I thought I should let people know : be careful when removing that sub-woofer connector!!!

I also broke the sub-woofer connector away from the board, the connection to the board is very fragile, however I managed to solder the connector back on with a very fine soldering iron, (tricky). but it worked. I don't think it is really necessary to disconnect the sub-woofer cable to remove the optical drive, I'll find out when I get a new one to replace the old broken one. To remove the subwoofer cable it would be necessary to hold the connector in place while the plug is very carefully prized up from the lead side without moving the connector socket.

Completed this one successfully. Now running OCZ 256 GB SSD in main bay and WD Black 320GB in optical bay.

PLEASE change Step 6 to not blindly pop the subwoofer cable off of the logic board. I also have broken this connection by following the instructions. The comments do not print out/are not shown on the pdf! Some people (like me) may never see these comments until too late.

My computer had a different optical drive than shown. Instead of the screws going through the body of the drive, it was secured by two screws at the corners opposite the screw by the connectors (i.e, along the wall where the CD slot is). In addition, in order to repair the drive, black tape sealing the unit had to be peeled back in order to open it (and the screws underneath the tape were placed slightly differently).
