The importance of the SMC in MacBook Repair
What is an SMC?
A system management controller is an intricate subsystem of Intel processor-based Macintosh computers that control various aspects of your computer. This small chip is located on the logic board, and it controls things like battery charging, thermal and power management, LED indicators, video mode switching, sleep, hibernate and wake systems. It’s sort of like a computer’s subconscious or involuntary muscle that helps it breathe easier and work more efficiently. Sadly, corrupted or damaged SMC hardware and software is not entirely unusual, especially for Mac computers.
The Role of the SMC in MacBook Pro and Macbook Air Repair
Before you take your MacBook in for repairs and parts replacement, it is of the utmost importance that you get it checked out by a certified Apple technician. This could save you a truckload of money on unnecessary repairs; especially if a faulty SMC is the problem. Something as small as a flawed system management controller chip could leave you wondering why parts of your computer are not working all of a sudden.
Since the SMC controls individual functions such as lighting and cooling, it’s very easy to misdiagnose the issue and go ahead to perform expensive redundant repairs. Once you suspect that your computer issues are not isolated cases but rather a connected series of related breakdowns, you need to rush it to the nearest Mac repair shop and get it looked at. But one question still lingers; how do you tell whether your SMC is indeed the cause of all your computer conundrums?
How Do I know If My SMC is Acting Up?
By looking at all the critical areas that rely on a fully functioning SMC, it’s quite easy to tell if you need to have yours repaired. Let’s look at the most susceptible areas that are telltale signs of a malfunctioning SMC.

Sometimes, some SMC problems can be solved by running a quick reset on your computer. To reset your SMC, disconnect the power, remove the battery, hold the power button down for 5 seconds and then reconnect the battery. After resetting and booting as usual, some less complex SMC issues generally solve themselves. But if the problems persist, then you need to seek professional help from certified Apple repair experts ASAP.
