Explanation

A laptop keyboard becoming distorted and no longer flat is a classic symptom of a swollen battery. Modern laptops typically use lithium-ion (Li-ion) or lithium-polymer (LiPo) batteries which can expand due to internal chemical reactions, gas buildup, or overheating as they age or fail. This expansion creates significant pressure, which can warp the laptop's chassis, push up the keyboard, and damage other nearby components like the trackpad. .
