Laptop Battery Will Not Charge, Drains Quickly, Overheats, or Looks Swollen
Symptoms
Use this guide when a laptop remains at the same charge percentage while plugged in, reports that it is connected but not charging, shuts down sooner than expected, becomes unusually hot, or has a raised trackpad, uneven keyboard, opening seam, or warped base. Some managed charging features intentionally pause charging near a target level, but swelling and extreme heat are never normal.
Urgent battery safety
Stop using and charging the laptop if the case is bulging, the trackpad or keyboard is lifting, seams are separating, there is a sweet or chemical smell, smoke, hissing, leaking material, or heat that makes the device painful to touch. Shut it down only if you can do so normally and safely. Unplug it without pressing on the swollen area, keep it away from flammable material, and contact support or site safety staff. If there is smoke or fire, move away and follow local emergency procedures.
Safe checks when there is no swelling or severe heat
Let the laptop cool. Shut it down and place it on a hard, dry, nonflammable surface with ventilation. Do not place it in a refrigerator or freezer. Resume checks only when it is at a normal temperature.
Inspect from the outside. Look for fraying, bent connector pins, discoloration, a loose plug, debris, or case distortion. Do not insert metal objects into a port. Stop if anything is damaged.
Use the correct approved power equipment. Connect the manufacturer-approved charger directly to a known-working wall outlet. A phone charger or low-wattage USB-C adapter may fit but may not provide enough power. If your organization issued another compatible charger, test it. Do not borrow an unverified charger.
Reconnect in a simple configuration. Disconnect docks and other accessories. Firmly reconnect the charger at the wall, power brick, and laptop. Allow 15 minutes, then check whether the charge percentage changes.
Restart once. A normal restart can refresh charging status. After restart, note the battery icon and any exact message such as "plugged in, not charging" or "service recommended."
Check battery condition using built-in settings. In Windows, open Settings, System, Power & battery and review battery usage and any smart charging indicator. On a Mac, open System Settings, Battery, then Battery Health. Record the status but do not change organization-managed settings.
Check for an obvious drain pattern. In the same built-in battery view, note whether one approved application has unusually high usage. Close work normally and quit that application. Reduce brightness temporarily and disconnect unused accessories. Do not install a battery optimizer or cleaner.
Consider the environment. Charging can pause when a laptop is too hot or too cold. Move it to a normal indoor temperature, keep vents clear, and try again after it acclimates.
What not to do
Do not open the laptop, remove or squeeze a battery, puncture a swollen cell, press a raised trackpad back into place, place weight on the case, or dispose of a battery in regular trash. Do not use improvised chargers, freeze the device, run unapproved cleaners, edit the registry, disable endpoint protection, or erase or reinstall the operating system. Never share passwords, MFA codes, recovery keys, confidential files, or customer data.
When to escalate
Escalate immediately for swelling, deformation, odor, smoke, leakage, severe heat, damaged charging equipment, or a battery exposed to liquid or impact. Otherwise, contact support if an approved charger is not detected, the charge does not increase after the checks, the laptop shuts off unexpectedly, battery condition says service is recommended, or runtime has fallen sharply over several days.
What to include in the ticket
Provide the make, model, asset tag, operating system, charger wattage if printed on the approved adapter, exact battery message, charge percentage before and after 15 minutes, battery health status, temperature symptoms, and checks attempted. Mention any recent impact or liquid exposure without including confidential business details. Photos of external swelling or cable damage are helpful if safe to take. Do not attach credentials, recovery keys, customer data, or confidential documents.
