How to Fix a Laptop Charger That Gets Extremely Hot
Sometimes, you can fix a hot charger at home. Other times, you need to replace it. Here are some easy steps to try:
1. Use The Right Charger
Make sure your charger matches your laptop’s model. Using the wrong charger can cause overheating. Check the voltage and wattage on the charger label. It should match your laptop’s needs.
2. Keep The Charger In A Cool Place
Never put the charger on soft surfaces like beds or couches. These block air flow. Use a hard surface like a table or floor. Keep the charger away from sunlight or heat sources.
3. Avoid Covering The Charger
Charging creates heat. Covering the charger traps heat inside. This makes it hotter. Always leave space around the charger for air to flow.
4. Check The Cable And Plug
Look for bent or broken cables. Damaged wires cause short circuits and heat. If the cable is broken, replace it. Do not try to fix it with tape.
5. Clean The Charger
Dust and dirt can build up on the charger. This blocks ventilation holes. Use a dry cloth to clean your charger. Make sure it is unplugged before cleaning.
6. Avoid Using The Charger For Too Long
Charging your laptop all day can make the charger hot. Give it breaks. Unplug the charger sometimes to cool down.
7. Use A Surge Protector
Power surges can cause the charger to overheat. Use a surge protector to protect your charger and laptop. This device stops dangerous electricity changes.
