Symptoms
- No light on the charger brick
- Laptop shows no charging indicator when plugged in
- Charger works intermittently, only at certain angles
- Charger gets warm with no charging happening
Likely causes
- CommonFrayed or broken cable, often near the connectorRepeated bending at the plug is the most common failure point.
- CommonFailed power brick/adapterThe internal transformer can fail with age or a power surge.
- PossibleBad outlet or power stripAlways worth ruling out before blaming the charger.
- PossibleDamaged charging port on the laptopA loose or bent port pin can mimic a bad charger.
- Less commonNon-original charger not fully compatibleSome third-party chargers under-deliver power or aren't recognized.
What to do
- Test the outlet with another device (lamp, phone charger) to confirm it has power.
- Inspect the full length of the cable for kinks, fraying, or exposed wire, especially near both ends.
- Wiggle the cable gently at the connector while watching for a charging light to flicker on, which points to an internal break.
- Try the charger on a different laptop, or try a different charger on your laptop, to isolate which part failed.
- Check the laptop's charging port for bent pins, lint, or corrosion.
- If the cable is detachable from the brick, try swapping just that piece if you have a spare.
Tools and parts
- Spare cable or charger if available

When to call a pro
If testing shows the laptop's charging port itself is damaged, have it inspected and repaired by a professional rather than continuing to use force on the connector.
Safety
Use caution
Stop using any charger with exposed wiring, a cracked case, or a burnt smell, and replace it before it causes a shock or fire risk.
