That increases heat inside the chassis.<\/p>\n<h3>C) Poor ventilation<\/h3>\n<ul>\n<li>Using the laptop on a bed\/blanket\/sofa<\/li>\n<li>Blocked vents or dust buildup<\/li>\n<li>Hot room temperature<\/li>\n<\/ul>\n<h3>D) High brightness, gaming, or GPU activity<\/h3>\n<p>These raise power draw and internal temperature, which can warm the battery area even if the battery itself is okay.<\/p>\n<hr>\n<h2>3) When heat becomes unsafe (stop using it)<\/h2>\n<p>Unplug the charger and stop using the laptop on battery power if you notice:<\/p>\n<ul>\n<li><strong>Swelling<\/strong> (bulging bottom cover, touchpad lifting, gaps in the chassis)<\/li>\n<li><strong>Burning\/chemical smell<\/strong><\/li>\n<li><strong>Visible warping<\/strong> or deformation<\/li>\n<li><strong>Very high heat<\/strong> that feels painful or alarming<\/li>\n<li><strong>Crackling sounds<\/strong> or any sign of smoke<\/li>\n<li><strong>Rapid new problems<\/strong> (sudden shutdowns, charging errors, percentage jumping + heat)<\/li>\n<\/ul>\n<p>These are not \u201cnormal battery warmth\u201d signs.
