Discovering that a MacBook Pro’s trackpad has popped out or the chassis appears inflated is a serious matter and should never be ignored. This issue typically signifies a swollen battery inside the device—an alarming but somewhat common occurrence, especially in older MacBooks or those with manufacturing defects or extensive use. A swollen battery poses a safety risk and should be addressed promptly and safely.
The trackpad pushing outward or the bottom casing appearing warped are consequences of internal pressure caused by the expansion of lithium-ion cells. If left unattended, a swollen battery can lead to further internal damage or, in rare cases, fire hazards.

Why Does the Swelling Happen?
Lithium-ion batteries degrade over time, and their chemical stability can be compromised by any of the following factors:
- Overcharging or faulty power adapters
- Extensive charging cycles beyond battery life expectancy
- Manufacturing defects
- Prolonged exposure to high temperatures
When any of these issues occurs, gases build up inside the battery casing, which leads to its expansion. In the tight internal space of a MacBook Pro, this expansion causes the battery to press upward against the trackpad and other components, potentially damaging the logic board or display in the process.
What To Do Immediately
When a swollen battery is suspected, it is crucial not to attempt to repair it yourself—puncturing or mishandling the battery can result in fire or chemical leakage.
- Stop using the MacBook immediately. Shut it down and unplug it from any power source.
- Avoid charging it. Charging can worsen the swelling and increase potential risks.
- Do not press on the trackpad or casing. Applying pressure can cause the battery to rupture.
- Move the device to a safe, dry area. Keep it away from flammable materials.
- Schedule a professional inspection. Contact Apple Support or visit a certified Apple Service Provider.
Repair and Replacement Options
Apple is well aware of the battery swelling issue and may offer warranty or post-warranty support, depending on the device model and situation. If your MacBook Pro is eligible for battery replacement—either under warranty, AppleCare+, or through a product recall—Apple may cover the full repair cost.
If the device is out of warranty, expect to pay for a battery replacement, which can range from $129 to $199 depending on the model. Be sure to:
- Use only authorized Apple repair centers
- Dispose of the swollen battery responsibly, as per your local e-waste guidelines
- Request internal checks to ensure no other components were damaged
Preventive Measures
While not all cases are preventable, you can reduce risks by following these tips:
- Charge using certified Apple chargers only.
- Do not overcharge or leave plugged in overnight excessively.
- Avoid using your MacBook on soft surfaces that can trap heat, such as beds or couches.
- Use battery monitoring software to track battery health over time.
Keeping a close watch on your MacBook Pro’s performance and physical condition can help detect issues before they become hazardous. If you notice anything unusual—such as a clicking sound when using the trackpad, uneven surfaces, or overheating—take time to investigate and seek professional advice.
FAQ
- Q: Is it safe to continue using a MacBook with a swollen battery?
A: No. You should shut down the device immediately and avoid using or charging it to prevent safety risks. - Q: How do I confirm it’s the battery that’s swollen?
A: The most common symptom is a bulged trackpad or casing. A service technician can confirm the issue after inspection. - Q: Can I replace the battery myself?
A: Replacing a battery in a MacBook Pro is complex and potentially risky. It is highly recommended to let Apple or an authorized provider handle the repair. - Q: Will Apple cover the cost of a swollen battery replacement?
A: If your device is under AppleCare+ or qualifies under a battery service program or recall, it may be covered. It’s best to check with Apple Support directly. - Q: What do I do with the damaged battery?
A: Never dispose of it in regular trash. Bring it to a proper e-waste collection or Apple Store for safe disposal.
Facing a swollen battery in a MacBook Pro can be alarming, but prompt action, safe handling, and professional repair can ensure both the laptop and its user remain safe. Always prioritize safety and avoid DIY fixes for internal battery issues.
