Explanation

A swollen (bloated) battery is a common laptop failure mode caused by lithium-ion cell degradation. When a battery swells, it can lose the ability to hold or deliver a charge, causing the laptop to fail to power on despite appearing to be charged. Since the AC adapter and power cord were confirmed functional, the battery itself is the next logical component to suspect. Swollen batteries also pose a safety risk and must be replaced.
