My laptop suddenly died, started sizzling, and began producing smoke. I unplugged it immediately and placed it on a stainless-steel counter. It has an internal battery, and the smoking stopped once it was disconnected from power. I later moved it outside and opened the case; nothing looks visibly burned or swollen, but the laptop and especially the charging port smell acrid and burnt. Is the battery likely safe, and what should I do next?

If you are comfortable opening the case and the laptop is completely cool, you can inspect for obvious scorching or disconnect the internal battery, but avoid touching or puncturing the battery pack. If it is warm, swollen, damaged, or still producing an odor, don’t handle it—keep clear and contact the fire department or local hazardous-device service. The storage drive may still be recoverable, but safety comes first.
Keep it away from anything flammable and do not plug it in or try to power it on again. Since it has an internal lithium battery, move it only if it is cool and safe to handle, and place it outdoors on a nonflammable surface such as concrete, away from the building. Don’t wrap it up or seal it in a container. Watch for heat, swelling, hissing, popping, renewed smoke, or a chemical odor. If any of those happen, move away and call emergency services. Even if the battery looks normal, the charging circuit or battery may have been damaged. Have a repair shop or the manufacturer disconnect and inspect it.
The smell is more acrid than sweet, and it seems strongest around the charging port.
The fact that it stopped smoking when unplugged could point to a failed charging port or power-management component, but that does not prove the battery is safe. A visual inspection cannot reliably rule out internal battery damage. Leave it disconnected and arrange for professional battery removal and inspection rather than following a generic online teardown guide.
I’ve opened this laptop before, but I’m not comfortable disconnecting anything while there may still be a fire risk.
