Hi! I recently replaced swollen battery on my 2018 15” MacBook Pro. After replacement there is a problem, sometimes charging adapter is not charging (the charging icon appears for a second and disappears), but this problem is not permanent. The charging adapter starts working if I plug it to an other MacBook Pro, or after waiting for a while, or if an other charging adapter is plugged in. Third-party service said that the problem could be caused with a faulty charging adapter and recommended to replace charging adapter. I didn’t replace the charging adapter yet, because I’m a little bit confused. Please help me, what should i do? I don’t know why my MacBook’s battery is swelled. If you need more details, i can answer to your questions.
Did you check if the battery is plugged in properly? and if your battery is showing up in macOS? If it is then it most probably is a battery issue. If it does not show up in macOS then you might need to open the MacBook and check the battery connection! Do let me know what you find out!
There is a couple of things I would do here: Installing this gem of an app! CoconutBattery. Take a snapshot of the apps main window and post it here for us to see Adding images to an existing questionGetting a USB-C power meter like this one Satechi USB-C Power Meter Tester So you can watch a bit better what is happening with your charger. These will allow you to see more clearly what’s happening with your system. I do have a few questions which might offer us some clues on whats happening. You talk about having access to a second system what is it? Is the charger the same or different?Are you using the original charger and the USB-C cabe that came with it or using something different?
