Product Details
Is the trackpad on your 13" MacBook Pro not clicking, not responding or not working at all? The trackpad flex cable joins the trackpad to the logic board, and a worn or torn cable stops it working. A new trackpad cable is a cheap part to try before a whole trackpad.
This cable fits the 13-inch unibody MacBook Pro A1278 from Mid 2009 to Mid 2012. Need the trackpad too? We stock the A1278 / A1286 2009 to 2012 trackpad.
Part Includes:
- 1x Trackpad flex cable
- 12 Month Warranty
Please Note
Does NOT fit the Late 2008 aluminium MacBook A1278, which uses a different cable. Check the year in About This Mac.
Please Note
This is the cable only. The trackpad and its screws are not included.
Please Note
The lower case comes off and the battery comes out. The trackpad unscrews to reach the far end of the cable.

Here are some helpful tips to assist you in completing a safe repair on your device. If you are unsure of something or have any questions, please feel free to contact us either by phone (0508 IGADGET) or by email
- Always power down your device prior to working on it
- Always unplug the battery before you remove any other parts, and keep metal tools away from the battery. Never bend, crush or puncture it
- The lower case screws are #00 Phillips and come in two lengths. Track them on a magnetic work mat or tape them to a drawing of your laptop
- The battery is held by tri-point screws, not glue. Lift it out by its plastic pull tab
- Lift the cable connectors with a spudger, never the sockets
- Peel back the clear tape over the cable with tweezers and stick it back down over the new cable
- The trackpad screws are small #00 Phillips screws along the inner edge. Hold the trackpad while the last ones come out, then refit them gently so the click still feels even
