This trackpad is for A1466 Macbook Airs from 2013-2015. The 2015 Macbook Air is still being manufactured into 2018.

A bad trackpad can

• Keep the keyboard/trackpad from working.
• Affect SMC reset so the machine cannot be turned back on properly after being shut down.
• Cause keys to work intermittently.

This trackpad very commonly corrodes after a liquid spill.
