my Mac's faulty logic board?

Have you ever visited an Apple authorised service centre just to be told your MacBook is unfixable? It happens quite frequently, and this is because the MacBook’s logic board is faulty. This page will explain why Apple authorised service centres cannot fix faulty logic boards and about Apple centre logic board repair. 

Apple authorised service centres or your local computer repair shops provide hardware services for your Mac by replacing faulty parts. This is called a level 1 repair or basic repair.  This type of repair is entirely dependent on the availability of the spare parts. If there are no spare parts then there is no fix, it is pretty straightforward for part-replacing types of repair.

A MacBook consists of the following parts:

A screen, a keyboard

A touch pad

A battery

A mechanical or SSD hard drive

A WiFi card,

A logic board

Cables connecting other parts to the logic board

All the parts except the logic board are available on the market from third party manufacturers or OEM manufacturers. For example, your screens are made by LG or Samsung, and your SSD drives are typically made by Toshiba or Samsung. You can read more about other Mac hardware here. The more manufacturers are involved, the better prices you can buy on the market.

The logic board is the “core" technology of Apple computers including the MacBook and iMac range. Apple goes to great lengths to hide the inner workings of this tech from third-parties, meaning it is impossible for third-party logic boards to exist. You may come across ads like “Apple original screen", or “Apple original keyboard", but never “Apple original logic board". This ensures only one type of logic board exists and is fully controlled by Apple.

Apple seems to be more interested in persuading you to buy a new Mac if a faulty logic board is found in an out-of-warranty device rather than repairing the logic board. Only those logic boards still under warranty will be sent out to overseas for repair (Foxconn China, manufacturer of logic boards for MacBook, iMac, iPhone). There is huge profit difference between selling a new Mac and repairing a faulty logic board. 

As a result, there are no spare logic boards available on the market, and the Apple authorised service centre or your local computer service providers are unable to find spare logic boards for your Mac. This means you end up with basically an “Apple genius bar certified dead" Mac.

We provide a logic board repair service at the chip level known as level 2 or manufacturer repair. At this level,  we are working on individual logic board components (or chips) such as CPUs, GPUs, ICs, transistors, resistors, capacitors and so on. The objective is to identify the faulty chips among the many thousands on the board and then replace them without damaging the surrounding chips. We repeat this process until all faulty chips are found and replaced, and all the functionality and stability tests have been passed. In one sense, it is like a meticulous forensic investigation. In order to perform the task effectively and economically, one needs the electronic knowledge, detective reasoning skills, micro-soldering skills, experience, proper equipment and most importantly: an understanding of the “core" design of the Apple logic board. Unfortunately, there are very few companies can perform this task effectively – and even less still in Australia. We are proud to be one of them.
