If your laptop trackpad is popping out, stop using it immediately

A trackpad that lifts or cracks often indicates a swollen lithium-ion battery pushing against the chassis, a condition that can lead to fire or explosion. Stop using the laptop, power it off, unplug it, and have the battery replaced—typically $149-$249 for MacBooks, often free under warranty. Maintaining proper temperature, using certified chargers, and storing at ~50% charge can help prevent swelling.
