What to do if…
your laptop battery is swelling and the casing or trackpad is lifting

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Stop using the laptop now: shut it down, unplug it, and move it to a cool place away from anything that can burn. Treat it as a damaged lithium-ion battery until the manufacturer, a qualified repair shop, or your local household hazardous waste program tells you what to do next.

Do not do these things

  • Don’t keep using it, charging it, or plugging it back in to check whether it still works.
  • Don’t press the trackpad or casing back down, clamp it, tape it shut, or force the lid closed.
  • Don’t puncture, bend, crush, pry, or squeeze the battery or laptop casing.
  • Don’t open the laptop or remove an internal battery unless the manufacturer says it is user-removable and it comes out without force.
  • Don’t put the laptop or battery in household trash, curbside recycling, or an ordinary battery drop box that has not confirmed it accepts damaged batteries.
  • Don’t leave it on a bed, sofa, paper pile, carpet, or near curtains, chargers, fuels, or other items that can burn.
  • Don’t mail or ship it unless the manufacturer, recycler, or disposal program gives you specific instructions for a damaged lithium-ion battery.

What to do now

  1. Shut it down. Use the normal shutdown option if you can do that without pressure on the swollen area. If it is frozen, hold the power button until it turns off.
  2. Unplug it and leave it unplugged. Disconnect the charger, dock, USB devices, external drives, and anything else attached to the laptop.
  3. Move it only if you can do so safely. Carry it gently without squeezing the raised casing or trackpad. Put it on tile, concrete, stone, or another hard non-flammable surface in a cool, ventilated area away from people, pets, and things that can burn.
  4. Watch for signs that it is getting worse. If you notice smoke, hissing, popping, a strong chemical smell, leaking, sparks, flame, or rapid heating, stop handling it and move people away.
  5. Call 911 if there is smoke, fire, rapid heating, or an imminent fire concern. Tell the dispatcher it is a swollen lithium-ion laptop battery.
  6. Do not turn it back on for data. If files matter, ask the manufacturer or a reputable repair shop whether they can remove the storage drive or recover data without energizing the swollen battery.
  7. Contact the manufacturer or retailer. Say: “The laptop battery is swollen and the trackpad or casing is lifting.” Ask for their handling, repair, replacement, recall, and disposal instructions.
  8. Check the correct disposal route before transport. Contact your local household hazardous waste program, local solid waste agency, state waste management agency, manufacturer, or approved electronics recycler and ask whether they accept a swollen or damaged lithium-ion laptop battery.
  9. Prepare for transport only if the item is stable and accepted. Keep the laptop powered off. If the battery is already separate and removable without force, cover exposed terminals with non-conductive tape or place the battery in its own plastic bag unless the disposal program gives different instructions. If the battery is internal, do not open the laptop; transport the whole laptop only as instructed by the accepting program.

What can wait

  • You do not need to diagnose why the battery swelled.
  • You do not need to run battery health apps, updates, antivirus scans, or backups right now.
  • You do not need to decide today whether to repair, replace, sell, wipe, or recycle the laptop.
  • You do not need to press the casing flat to make it look normal before service.

Important reassurance

A swollen laptop battery is alarming, but the safest first steps are simple: power off, unplug, isolate, and get instructions from a qualified route. Acting early and not forcing the casing or battery helps reduce the chance of a worse incident.

Scope note

These are first steps only. Later decisions about repair, data recovery, warranty, replacement, shipping, or disposal may need help from the manufacturer, a qualified repair shop, your local household hazardous waste program, or an approved electronics recycler.
