Ok. but how that can be faulty when the laptop works great? I have no other issues apart from what I said.

Привет всем. Им с помощью Google Translate для перевода с английского на русский. У меня есть неисправный MacBook Pro 13 "A1278. Аэропорт Trackpad и Ethernet порт не работает. Я купил новый трекпад и он по-прежнему не работает. Кто-нибудь имеет никакого понятия, как исправить? Есть ли неисправный компонент на логику платы, которая прошла плохо? С уважением |

Write in english. Real engineers knows english. I think You have the trouble with ethernet chip first. USB is working? All other devices? |

The trackpad was working but it has now stopped. The camera works but if the airport card is connected, the macbook wont boot up. Where to find this chip? I know if a device on a mac is not working then few others may not work because of it. |

When install the new and old airport card - same defect? You wrote -Ethernet (i.e. LAN, i.e. cable connection) not working too. Is it correct? |

There is a ribbon that attaches the camera and airport card. If I attach that ribbon to the logic board, the laptop wont boot up: stays on white screen (no apple logo no nothing). If the airport card is removed all is ok. So while the airport card not is not connected, the camera works great. If change airport card with a known working one, same result. Ethernet (LAN) does not work. Shows not installed. |

AirPort and Ethernet connected via PCI bus. Perhaps you have defective (burning) Ethernet chip and he block other devices like AirPort and TrackPad. If PCI bus not working or works incorrectly it usually means that faulty Northbridge. You must have special equipment like BGA rework station and special skills to replace Northbridge. Try to "Reset SMC" first - may be it's helps You. |

PERHAPS NorthBridge. If You have tools - You must have the advanced diagnostics skill first. My online diagnosis is only assumptions. |
