If the MacBook is a tantrum and you often have problems with the detection of the battery or the management of the fan, the ultimate solution could be really simple and I’ll explain it to you in this article!

Many owners of MacBook Pro and MacBook Air have asked for help in forums and Mac support centers complaining of an annoying problem involving the battery and the cooling fan; in particular, in some of these Macs the battery is not always recognized causing problems during the use of the computer such as interrupting the charging or unexpected shutdown of the notebook while in others there is an irregular activity of the cooling fan.

As there have been numerous reports, Apple has published a guide in support that indicates a possible solution to these problems: the reset of the SMC.

How to reset the SMC of the Mac?

The SMC reset is a technical operation but very simple to make and above all does not endanger the proper functioning of the Mac.
Before resetting the SMC, a computer on I suggest you put the Mac in STOP using the  Apple menu of OSX; reactivate the system and restart it, finally switch off the Mac completely using the “Turn off …” item from the Apple menu.

If the system does not respond to commands, try the forced shutdown by holding down the power button for more than 10 seconds.

After performing these preliminary steps, you can reset the SMC but you must follow the instructions according to the computer in your possession.
