Laptop Battery Swelling: Causes, Safety Steps, and Recall Check

You probably won't see the battery itself — it's sealed inside. What you'll notice is what the swelling does to the laptop around it.

Warning signs:

• The bottom of the laptop has a visible bulge or bow
• The trackpad feels raised or won't click properly
• The keyboard feels uneven or pops up in the middle
• The lid won't close all the way, or looks misaligned
• The laptop rocks on a flat surface when it used to sit flat

If two or more of these are true, treat it as a swollen battery until proven otherwise.

Lithium-ion polymer batteries generate small amounts of gas as a normal byproduct of charging and discharging. Usually the cell manages this fine. When it doesn't, gas accumulates and the flexible pouch that contains the battery expands.

The main causes:

1. Age and cycle wear. Every charge cycle degrades the battery slightly. After 300–500 cycles (roughly 2–4 years of daily use), the internal chemistry gets less stable. Gas buildup becomes more likely.

2. Heat. Leaving your laptop in a hot car, running it on soft surfaces that block vents, or heavy CPU/GPU use in a warm room all accelerate battery degradation. Heat is the single biggest accelerator.

3. Overcharging patterns. Keeping a laptop plugged in at 100% constantly stresses the cells. Modern laptops limit this somewhat, but older charging hardware doesn't always handle it well.

4. Manufacturing defects. This is the recall category — where a batch of batteries was built with a flaw that causes early or unpredictable swelling. Lenovo ThinkPad X1 batteries, several Dell models, and multiple HP lines have had formal CPSC recalls for exactly this reason.

Do these steps in order:

1. Stop using the laptop. Close it and unplug it. Don't charge it, don't run it. A swollen battery is under mechanical stress — continued use increases the risk of puncture, which releases toxic gases and can ignite.

2. Move it somewhere cool and uncluttered. Away from papers, curtains, or anything flammable. Don't put it in a drawer or a bag — you want airflow and visibility.

3. Do not try to remove the battery yourself. Modern laptops have non-removable batteries bonded to the chassis. Prying it out without training punctures cells. If yours has a removable battery (most pre-2015 laptops do), you can remove it — but set it on a non-flammable surface and handle it by the edges only.

4. Do not throw it in the trash or recycling. A swollen lithium-ion battery is hazardous waste. It needs to go to a certified electronics recycler or a hazardous materials collection event. Call 2-1-1 or search earth911.com to find a drop-off near you.

5. Check for a recall before paying for a repair. If your laptop is on an active recall list, the manufacturer will replace the battery free. This is the step most people skip. Don't pay for a repair until you've ruled this out.

Several major laptop battery recalls are currently active or recently expired. Check your brand below.

Dell

Dell has issued multiple battery recalls going back to 2001. The most significant recent one covered specific Inspiron, Latitude, Precision, and XPS models.

• Check your model number (found on the sticker on the bottom of the laptop, format: Inspiron 15 7000 or XPS 13 9310)
• Visit dell.com/support and enter your Service Tag for recall status
• Active recall info: cpsc.gov/Recalls (search "Dell battery")

Lenovo

Lenovo has recalled ThinkPad batteries for fire hazards multiple times. A 2024 recall covered Lenovo USB-C laptop power banks (model PBLG2W). Earlier ThinkPad recalls covered the X1 Carbon and several T-series models.

• Find your model: press Fn+F10, or check the label on the bottom
• Check status at: support.lenovo.com/us/en/solutions/HT503659 (ThinkPad battery recall page)
• CPSC notice: cpsc.gov/Recalls/2024/Lenovo-Recalls-USB-C-Laptop-Power-Banks-Due-to-Fire-Hazard

HP

HP has issued several battery and power adapter recalls. The HP Spectre x360 battery swelling issue (reported 2025) is currently under investigation — no formal recall yet, but HP is handling cases individually.

• Find your model: label on the bottom, or Settings > System > About
• Submit a support case at hp.com/us-en/hp-information/recalls.html
• If HP declines: file a complaint at saferproducts.gov (CPSC consumer reporting portal)

Apple (MacBook)

Apple issued a major recall in 2019 for the 15-inch MacBook Pro (2015 model), where batteries posed a fire hazard. That recall is now closed, but Apple still handles battery swelling cases through its Genius Bar or Apple Authorized Service Providers.

• Check your model: Apple menu > About This Mac
• Book a Genius Bar appointment or contact Apple Support — they will assess it in-person
• Swollen MacBook batteries are often repaired or replaced out of warranty at no cost if tied to a known issue

No. The FAA prohibits carrying laptops with known battery defects on aircraft. Even in checked baggage, damaged lithium-ion batteries are prohibited. If your laptop has visible battery swelling, do not bring it on a flight until the battery is replaced.

Call the manufacturer first if:

• Your laptop is under warranty
• You found your model in a recall list
• The laptop is less than 3 years old and you've had no abuse or heat incidents

File with CPSC (saferproducts.gov) if:

• The manufacturer declines to help and you believe there's a safety defect
• You've had a fire, smoke, or burn incident — report it regardless of what the manufacturer says
• Multiple people in a forum are reporting the same issue on the same model

Your report goes into the CPSC database and may trigger a formal investigation. It only takes a few minutes.
