The full spec calls for up to 20V 5A or 100W, but (obviously) can be lower due to a lower overall wattage rating. It starts off with a 5V nominal voltage, but then can go as high as 20V at about 3A (≅ 61W). This chip is what negotiates the charging power to be delivered from the USB-C ( USB-PD compliant) power adapter. There have been reports that the USB Mux chip (TI CB3215) is faulty. This "battery not charging" message is perfectly normal when this function/feature is enabled. With the release of Catalina (10.15.5), there is a feature called Battery Health Management that will actually stop the charging of the battery at a certain battery charge range. There are a couple of possibilities that can be attributed to this: Battery Health Management When charging my MacBook Pro (mid 2017, macOS Catalina 10.15.7) with the 61W USB-C Power Adapter from Apple, sometimes the "battery is not charging" warning start appearing from nowhere draining the battery. When using another power adapter on the macbook, it's charging slowly (but coming from a 12W power adapter and a USB-A to USB-C cable that seems fair enough). When using the power adapter from Apple and the USB-C cable on another device (unfortunately a phone and not another Macbook), it's charging normally. After the logic board and battery being replaced, the issue is still here.Ī full discharge, then a full charge didn't fix anything. The "battery is not charging" issue start happening early this year, but the Macbook had another issue with the logic board as well.

Why is this happening ? (Sometimes while the battery is full and still plugged, sometimes while charging) Zoom just fixed a major security flaw on Mac.When charging my Macbook Pro (13 inch, mid 2017, MacOS Catalina 10.15.7) with the 61W USB-C Power Adapter from Apple, sometimes the "battery is not charging" warning start appearing from nowhere draining the battery (from every one of the 4 ports available).īy looking up the charging information (using Istat Menus) it appear that the Macbook think that the 60W charger is in fact a 12W one (and it appear that the intensity is negative i.e not charging):īy unplugging/plugging back the USB-C cable (sometimes several times) all comes back to normal

The Dell XPS 13 Plus has the M2 MacBook Air beat in this one important way We do not know whether it will fix this particular battery glitch, but we have our fingers crossed. We know Apple is working on at least one aspect of how its Macs charge up, with a new Battery Health Management system included in the latest beta for MacOS 10.15.5.

Until a MacOS update is rolled out, your best bet is to avoid having both your charging lead and peripheral devices plugged into the MacBook Pro’s left-hand side. It is not really known why this situation exists, but it is likely unintentional on Apple’s part. Even though the ports get warm during use, kernel_task is seemingly ignored by MacOS in this instance, meaning no resource-hogging process slowing down your Mac. The same is not true if you use the right-hand ports. While charging the MacBook Pro and having peripherals plugged in to the left-hand ports, the device’s ports can get hot for some reason, this can result in kernel_task going a bit haywire and using up a whole boatload of system resources. As Apple explains, the kernel_task process manages the processor temperature in MacOS, in part through controlling the device’s fans - when the operating system detects high temperatures, it prompts kernel_task to start spinning the fans. The resource-hogging process made things so bad that their MacBook Pro became “effectively unusable” at times.Īs it turns out, the root of the problem was not kernel_task itself but rather the situation that was forcing it into action. One user on the programming community Stack Exchange had struggled to work out why the kernel_task process was using so many resources on their computer - including causing their machine to wake from idle a whopping 990 times. Given that one of the selling points of Apple laptops is near-silent operation, that is less than ideal. When charging the laptop using one of the left-hand USB-C ports, the laptop gets unusually hot and the fans start spinning to counteract the increased heat.

The issue seems to affect USB-C MacBook Pro models, meaning any high-end Apple laptop from 2016 onward.

Only charge it using the ports on the right-hand side of your device. If you own a MacBook Pro (if you don’t, you can always get one with a discount thanks to the Black Friday MacBook deals) and have noticed it gets hot while charging, there could be a simple solution.
