As the heart and soul of the computer, MacBook Logic Boards are the Apple equivalent of a motherboard inside a Mac computer. This central component of the Mac computer relegates many if not all the tasks that the Mac is put through; everything from the operation of the fans to controlling the speed of the processor, as well as devices plugged into the USB slots all involve the use of the Logic Board in some manner.
Like all pieces of hardware, the MacBook Logic board will eventually come to a time where its lifespan runs out, and eventually dies as a result of natural causes. Some, however, will meet their untimely end sooner than most as a result of other internal or external causes like faulty manufacturing or user errors, so diagnosing problems in the MacBook Logic board can prove crucial in taking advantage of the warranty or paying for repairs if it has expired.
The Logic Board
One of the central-most parts of any computer system is the motherboard. In an Apple computer, this part is commonly referred to as the logic board instead of the motherboard, but has many of the same functions as its PC counterpart. This crucial purpose includes holding together all of the required components that a computer needs to run, like the processor, video card, RAM, hard drives, and other peripherals inside the CPU.
The earliest Apple computers had this component, which was still similar to other motherboards of the time. The term “logic board” was simply a mainstay of the Apple employees of the time, but managed to follow them all the way up to the current generation of Apple computers like the MacBook, as well as other Apple products.
Motherboards and Logic boards of today are specially designed to be modular in nature, with most of the parts that a computer needs to run being easily swappable in case of a failure with that particular component. The MacBook Logic board, however, needs to be serviced by officially licensed and certified Apple technicians, lest you void the warranty when trying to do so yourself.
Plugging in peripherals through the USB, display and other ports on the system does not typically count as voiding the warranty, however. Over the years, the motherboard and MacBook logic board have evolved to support all kinds of peripheral card slots, including these USB and other memory card slots. In the current generation of MacBook logic boards, support for SD cards is standard in addition to the usual USB ports.
A computer as advanced as the MacBook is designed to operate even with the heaviest and most resource-intensive tasks you can possibly imagine, placing much strain on the logic board. The logic board in your MacBook, however, is tailor-made to control cooling depending on the stress being placed on the system. The logic board is designed to withstand high temperatures, so while many complain that the MacBooks of today run in excess of 100 degrees Celsius when under heavy stress, not much damage is done to the motherboard.
MacBook logic boards, especially the ones on the MacBook Air series, are designed to have much more compact form factors in order to maximize space and cooling within. This compact form factor that the MacBook logic boards have also ensure closer integration between internal components, making for a faster and smoother overall computing experience no matter what kind of task you may be doing on the MacBook.
Any form of mass-produced technology can be susceptible to failure, however, and the MacBook logic board is no different. A myriad of problems can arise on a MacBook just like any other computer, but with the aid of an able Apple technician, your MacBook will be up and running in no time.
Common MacBook Logic Board Problems
No computer system is designed to be completely and utterly without its problems, and the MacBook is no different. Despite extensive product prototyping, development and testing, the MacBook logic board may have its share of problems, especially after continuous strenuous usage in resource-intensive tasks.
A complete failure of the MacBook logic board can be a common problem that many Mac users face. The dreaded “black screen of death” is one of these problems; when the MacBook boots up, the parts of the Mac itself can be heard running, but nothing appears on the monitor. This kind of problem can be diagnosed to a fault in the logic board, and typically means that it has reached the end of its lifespan and has simply died out.
Not all problems with the logic board are as grievous as a complete and utter failure of the unit itself; a simple slowdown in programs, tasks, or the overall operation of your MacBook can be the result of a faulty MacBook logic board. Simply consulting a trained Apple technician about the problem can easily alleviate this problem, and may not even entail the complete replacement of the logic board itself.
Some problems thought to be caused by the logic board may simply be solved by a little regular computer maintenance. Much like any other machine, the MacBook may need a little maintenance from time to time, like defragmenting the hard drive or cleaning out the computer of excess files and other bulk. While the Mac is thought to be virus-free, it is not, so opt for a good anti-virus program to keep harmful files, viruses, malware and worms away from your MacBook logic board.
