All technology products have a chance of failing and spoiling your experience with it. Macs are not exempt from these random glitches when turning them on. In this article we try to help you in any way possible to solve boot problems on a MacBook Air.
Check the charger and connectors
One of the first causes that can be thought of when the computer fails to start is the failure of the battery charge. It is important to always check that the charger is in perfect condition and that it fits perfectly into the wall socket. In order to verify that it is not a problem with the charger, you can try charging with the other device. If it starts to recharge, it is not a problem with the transformer or the cable.

The connections where the charger connects to the MacBook Air may also be the focus of the problem. Like any other port, it may have been dirtied with a certain amount of dust or lint, preventing a perfect pin engagement. Also the use and humidity of the environment can cause that in the end it does not work as expected the charger. In these cases, it is recommended to go to an Apple Store to receive specialized help.
Check if the operating system fails
On certain occasions it may be the case that there is not a hardware problem but a software problem. If in the case of pressing the start button, the hardware starts but does not finish loading the operating system, being completely stuck in the initial processes. In these cases, it is recommended to reinstall the operating system through the macOS recovery options over the internet. In order to access this function, you simply have to hold down the ‘Command + Option + R’ keys. Within these recovery options you simply have to click on ‘Reinstall macOS’ so that the operating system is downloaded again and is overwritten.

Obviously, to perform an installation, clean and erase all traces that exist from the previous operating system. This is simply done in the ‘Disk Utility’ section where you can choose the main hard disk and erase all the content on it. Once this is done, you can go back and click on ‘Reinstall macOS’.
Battery problem
One of the most obvious failures that can occur is undoubtedly related to the MacBook Air battery. In the event that sufficient power is supplied to you through the connectors or the charger, it is very likely that the condition of the battery has been corrupted and a change is necessary. In no case should a home repair be carried out with your own hands, since in addition to losing the warranty that you have with Apple, it can also end up causing more severe problems. That is why you should always go to an Apple Store or an establishment that is authorized to carry out repairs, the so-called SAT.
In the event that you have a warranty on the equipment in the vast majority of cases the battery is covered unless there is a blow. If this is not the situation, you must make an extra payment that is 139 euros according to the official prices of the Apple Store.

Graphics card or RAM problems
The battery is not everything in a computer since the other internal components also play an important role when it comes to booting the device. The graphics card is one of them since it is mainly responsible for processing all the images that are displayed on the computer screen. Obviously this is a pretty annoying bug as no home process can be done to fix it. You can only go to an expert to perform this task, which may involve changing the entire processor. We must remember that MacBook Air mostly have an integrated graphics card and not a dedicated one. This makes the repair much more expensive in the event that it does not have any type of guarantee in force.
Poor RAM placement or a totally faulty RAM can almost always cause the computer to boot for a few seconds and shutdown without continuing. The fact that it receives a strong shock can cause the RAM to move slightly from its location causing all these problems.

Storage failure
The HDD or SSD storage drive carrying a MacBook Air may also end up failing in the long run especially the first option despite having Fusion Drive. It stands to reason that if it fails you cannot under any circumstances load the operating system that is stored here or reinstall it. Sometimes the computer may not start or display an error message. In these cases, it is important to make a repair immediately, even though the information may be lost. But in a specialized store it is often possible to retrieve the information on the replaced hard drive.

Temperature damage
You have to be very careful with the conditions in which a Mac is being used. Humidity and also temperature values should be kept within normal ranges. It is obvious that in no case should the computer be taken to the beach or pool or to the bathtub to avoid the risk of getting wet. It is already known by all that technological products and water do not have a very good relationship and that is why it should always be avoided. Damp rooms should be avoided at all costs as high levels of water in the environment can cause the MacBook Air to not perform as expected.
Temperature is another key factor to keep in mind. The processors are prepared to withstand a specific temperature. Above all, you must keep in mind the voltages to which it can be subjected because this is decisive for it to start correctly. If you look at the Apple website, it is recommended that the equipment is between 10 and 35º . Failure to adhere to these temperatures can lead to severe problems with the internal components of the MacBook Air.
Finally, repairs should always be carried out through the authorized technical service. In the event that you have made a replacement at an unauthorized site, there are problems that can cause the battery to be incorrectly installed. It is likely that a technician who does not have the necessary knowledge does not install correctly, causing startup problems.
