A laptop that will not charge does not automatically need a new battery. The outlet, charger, cable, charging port or computer itself may be involved. Start with observations you can make without opening the case.
Stop if anything looks unsafe
Do not keep using a damaged charger or a laptop with a swollen battery. A separating case or lifting touchpad can be a reason to stop and seek advice. Do not press the case closed, puncture a battery or attempt to remove a stuck battery. If there is smoke or an immediate fire hazard, move away and contact emergency services.
Check the power path
If everything appears undamaged, make sure the charger is connected securely at the wall and laptop. Try a different known-working outlet. Inspect the unplugged cable and connector for obvious damage without bending pins or forcing anything into the port.
Use a charger approved for your exact laptop model. A connector that fits is not enough to establish compatibility. With USB-C laptops, the charger, cable and laptop port must support the power arrangement the computer requires.
Record the exact behavior
Does the laptop run while connected but switch off when unplugged? Does Windows show a charging message? Does the charger light turn on, stay off or change when connected? Does the problem happen directly at the laptop or only through a dock?
Write down the battery percentage and any warning rather than repeatedly draining the battery to test it. Some models have charging limits or battery-management settings, so stopping below 100 percent does not by itself prove a failure.
Do not buy parts on a guess
Before ordering a battery, gather the model number, charger information and symptoms. Manufacturer guidance and model-specific testing can help distinguish a power adapter problem from a battery or port issue. Avoid firmware updates while power is unreliable unless the manufacturer or a technician provides an appropriate procedure.
