Is it possible to programmatically test a Surface Laptop battery?

Question

Rechargeable batteries

Surface Laptop noticed for a week that the top of the trackpad clicked harder than the bottom and the keyboard began to flex more. He suggested that inflating the battery. Disassembling a laptop is very difficult and the question is as follows. Is it possible to programmatically indirectly see signs of a swollen bacterium? Microsoft is asking $400, considering shipping is expensive. It's more of a safety issue for using a laptop, maybe it's something else?

Answer 1

According to the experience of operating a car DVR: as the battery capacity fell, it turned out to be swollen. And vice versa: as it swelled up, there was no capacity left.
Indirectly: check your battery life.
