Carefully inspect the macbook. We look at the external condition, the consequence of bumps and falls, careless use. Please note that:
Passwords that need to be taken from the client for full diagnostics of the MacBook:
Check the battery charging cycles. 1200 battery recharge cycles, after which it is recommended to replace the power source. Any battery pack has physical wear and tear. As a result, the capacity decreases, and the resistance may increase. For a full test, you can download the CoconutBattery program from the App Store. Which will show the capacity, which directly depends on how the MacBook battery holds less charge. If the laptop is more than five years old, a new battery may be installed and it is not always the original one.
To fully check the screen, you need to use the app or check online. You can recommend the free Screen Utility program. We check for artifacts, stripes on the screen, and window memorization. And also carefully inspect the display, setting the brightness to the maximum level, to identify “broken” pixels.
We check the performance of all ports. In the latest models, we also test the Thunderbolt 3 (USB-C) port. 3.5 mm headphone Jack. In a 2015 Apple laptop, if the audio driver is not working properly or is not working correctly, a red led will light up inside the connector.
Check the speakers by turning on music playback at full volume. At the same time, there should be no wheezing or other noises. The speakers should work correctly at different volume levels. Since 2016, the volume in the macbook is slightly higher than in previous models (do not forget about this).
The microphone can be checked via Face Time or via Skype. If the screen was replaced, the camera and microphone may not work. You should pay attention to the operation of the green led located next to the camera. Be sure to check the operation of the Bluetooth and Wi-Fi module. To check the Bluetooth settings, connect the mouse or headphones. MacBook repair is necessary when the device is detected but does not connect. Either it connects and doesn’t work, or it immediately disconnects.
