Apple says MacBook and MacBook Pro models with Thunderbolt 3 ports have a new power management system after upgrading to macOS Catalina 10.15.5.
If it is turned on, the device intelligently determines whether it should be charged or it is better not to gain energy in order to extend the life of the battery and delay its chemical aging.
To do this, the device monitors usage patterns and constantly monitors the temperature of various components, including the battery.
Why my MacBook won’t charge?
- Bad contact. First of all, check the charging port for dirt and dust.
- Charger defective. Inspect the power adapter and cable for any kinks, kinks, or other damage. Also pay attention to the indicator on the charging block, if the green light is off, then most likely it is faulty.
- Using non-original charger or wrong power.
- Critical battery condition. It may be worn out or swollen. In such cases, the system goes into protection and the MacBook does not charge.
If checking these points did not give any results, then move on.

Check the battery status if your MacBook won’t charge
Each battery has its own resource, calculated for a certain number of charge-discharge cycles.
You can check its status by opening the Apple menu and choosing System Preferences → Battery.
There will be a current cycle counter and one of the current states: “Normal”, “Service recommended”, “Battery may be faulty”.
You will not be able to fix a worn-out battery. The only solution to the problem is to replace the old battery with a new one.
Resetting the SMC
Sometimes the problem can be solved by rebooting the system management controller:
- Shut down your computer and connect it to your network using a MagSafe or USB-C power adapter.
- Press the Shift-Control-Option key combination together with the power button and hold it there for 10 seconds.
- Turn on your MacBook.
Always try to use the latest version of MacOS. Some updates may improve the connection between the computer and the charger.
Clearing errors in PRam and NVRam memory
(Non Volatile Random Access Memory), abbreviated as NVRAM, is a kind of operational five, capable of storing data without power supply.
The current is supplied through a separate channel, regardless of whether the laptop is turned off or in sleep mode. The following parameters are stored in NVRam:
- – MacOS volume level.
- – Display resolution.
- – Active boot area.
(Failure of the boot volume, causes the “?” Folder to appear on the desktop when starting MacOS)
- – Log of critical errors.
(If this log remains saved, then after fixing the malfunction, the laptop continues to assume that it is still present)
Defective MacBook power supply
The check should start with the block, connecting a 100% working, compatible charger or using a special adapter, because MagSafe generations are different.
Attention! The block must be of the same capacity with which you charged your Mac. The 45w block from the MacBook Air is not enough to charge the MacBook Pro, which has 60 watt, for 13 inch and 85 watt, for 15 and 17 inch models.
If the MacBook won’t charge from the old charger, but the battery charge is higher than 15%, when the 45w power supply is connected, the power indicator on the MagSafe connector may light up, but the battery will recover very slowly.
If the laptop is not turned on, perhaps such manipulations will not help. The chargers supplied in the kit and their copies, class AAA and A +, are made from good, high-quality parts and last up to 5-7 years, but over time, the characteristics and output voltage level changes and sags.
Capacitors can burn out and without ringing a multimeter, this malfunction cannot be detected. An oscilloscope will also help in detecting a breakdown.
In addition to exceeding the service life, the charger breaks down due to a voltage drop in the network and contact with water.
Checking the MagSafe or USB-C cable
You can verify that your Mac is functional by plugging in a different charging cable. If charging has started, there is most likely a charging problem.
If there is no other charging, then you can shake the cable or adapter extension slightly while the charging is connected.
If charging starts at certain points during rocking, then you need to disconnect it and not do this anymore – most likely there is damage to the cable or extension cord, but everything is fine with the device. In this case, it is possible to repair the MagSafe.
