Always keep your laptop away from a heat source because it can affect battery health.
3. Inspect the Charging Tools
If your laptop is not charging, may be the culprit is charging cable or the adapter. Make sure the cable is not bent or twisted, has no signs of wear and tear. Firmly connect the adapter to the laptop and power socket. Make sure that the wall power socket is supplying enough power and is not defective.
If possible, try charging your laptop with a different adapter. If the new charging adapter works, just replace the current one.

Dirty charging ports are very common reason for charging issues. This not only happens with laptops but also with other devices like smartphones or headphones.

Use a clean toothbrush, stick tack, microfiber cloth, or cotton swab to remove the dirt. You can also use a compressed air can, but blow the dirt out gently. Check whether the battery charges after cleaning or not.
