Know the 3 most likely causes and find out how to solve them!

< /p>

The Macbook may display several errors that cause it to not turn on, especially if the model is older. The reasons may be varied and may be related to a faulty charger, a worn-out battery, or other hardware defects. In many situations, the computer may stop responding due to a critical software failure, for example.

Some difficulties with your Macbook manifest themselves as follows:

Device very slow or unresponsive< /span>
Equipment does not turn off
Device shuts down or restarts unexpectedly
Applications or system unresponsive
Device startup is not performed< /span>
Equipment does not turn on
Battery drains too quickly
Signs of a swollen battery

For starters, the ?Apple Diagnostics? is a tool you can use to diagnose problems with your Macbook's internal hardware components, but this diagnostic does not check external hardware components, such as USB, or non-Apple devices, such as third-party PCI cards. It also does not check for operating system-related issues or software-related issues, such as app conflicts. Below we list the 3 most common causes of difficulties reported by Macbook users.

Loader

Start the investigation from the loader. On models manufactured with a magnetic MagSafe connector, check that the LED indicator on the tip that fits into the computer is on. If the light does not come on, examine the cable and look for cracks that may indicate a break in the power supply from the power adapter to the Macbook. On the other hand, the connection port or charging port is one of the components most susceptible to failure. The equipment may no longer recognize the power adapter or charger. On the MacBook Air, the task is very simple: leave the original USB-C cable aside and try another of the same type. Even if it is not a cable with 20V and 5A specifications, such as a smartphone charger, the MacBook should respond after a few minutes when plugged in.

Battery

If the problem persists, it is possible that the battery has a problem. The most recent MacBooks, for example, do not allow you to remove the battery to check operation using just the power cable, but it is possible to try some tricks to make sure whether or not the component is giving a positive response:

Start by pressing the power button /shut down to see if your MacBook makes any sounds or displays lights, such as the Caps Lock indicator. If there is no sign of operation, keep the button pressed for 10 seconds, release and press again;
If nothing happens, the battery may responds again after a reset of the System Management Controller. To do this, press the Shift+Control+Option keys on the left side of the keyboard and the on/off button simultaneously. Hold the button pressed for 10 seconds and release all keys at once. Then press the power button to turn on your MacBook.

It is important to highlight that battery problems may influence the performance of the equipment causing, in some situations, , it is abnormally hot. It is always crucial to carry out a Macbook battery assessment. The number of battery cycles will indicate whether it is a problem with the battery, in which case it will need to be replaced, or whether it is a software problem.

Operating system b>

When the MacBook failure is in the system, the computer usually turns on normally and displays some error code or symbol on the monitor, such as an exclamation mark.

If this occurs, try the following:

Start in safe mode: hold down the Shift key and turn on your Macbook normally. Hold down Shift until the end of the boot process;

Reset NVRAM (non-volatile random access memory): hold down the Option+Command+P+R keys and turn on the Macbook. Keep pressing for about 20 seconds, during which time the equipment may appears to be restarting.

If none of the above solutions work, we recommend reinstalling the operating system.
