Swollen Laptop Battery Indicated by Popping Trackpad Poses Fire Risk
Key points
- A popping trackpad signals a swollen battery.
- Swollen batteries can damage laptops and cause fires.
- Lithium-ion batteries swell from overcharging or damage.
- Stop using the laptop immediately and seek repair.
Recognizing a Swollen Battery
Modern laptop trackpads are typically flat. If a trackpad appears loose, pushed from the inside, or the glass covering it cracks, it may indicate a swollen battery. This condition is a serious issue that requires immediate attention.
Why Batteries Swell
Most modern laptops use lithium-ion batteries. These batteries rely on chemical reactions to provide power. Overcharging or physical damage can cause internal chemical components to produce harmful gases, leading to the battery swelling. The battery is often located beneath the trackpad in laptops, including Surface laptops and MacBooks, causing the trackpad to be pushed outwards when it swells.
Risks of a Swollen Battery
A swollen battery can damage internal laptop components. More critically, it poses a fire hazard, as it can swell to the point of explosion and ignite. While other hardware malfunctions can cause a loose trackpad, a swollen battery is a significant risk that should be ruled out.
Immediate Action and Prevention
If a laptop's trackpad is popping up or the case is bulging, the laptop should be turned off and unplugged immediately. The recommended course of action is to take the laptop to a repair professional. Apple has previously initiated replacement programs for MacBooks with swollen batteries, highlighting the seriousness of the issue.
