Chromebook charger gets very hot

Symptoms

• Charger brick is too hot to hold comfortably
• Discoloration or a burning smell near the charger
• Charger works intermittently
• Cable is warm along its length, not just at the brick

Likely causes

• CommonNormal warmth from chargingChargers commonly run warm, especially with fast charging, and this alone isn't dangerous.
• PossibleDamaged internal wiring generating excess heatA frayed or damaged cable can create resistance that generates heat and is a fire risk.
• PossibleNon-genuine or low-quality chargerCheap, uncertified chargers are more prone to overheating and are less safe.
• Less commonShort circuit inside the chargerA failing charger can develop an internal short that generates significant heat.

What to do

1. Feel whether the heat is coming mainly from the brick (usually normal) versus along the cable (more concerning).
2. Unplug the charger immediately if you notice discoloration, a burning smell, or it's too hot to hold.
3. Do not continue using a charger that is hot along the cable length or has visible damage.
4. Check that the charger is a genuine or reputable-brand replacement rated for your Chromebook's wattage.
5. Replace the charger with a certified one if you notice any of the warning signs above.
6. If the Chromebook itself gets unusually hot even with a good charger, that's a separate issue worth checking on its own.
