Symptoms
- Laptop shows 'charging slowly' or no charging indicator with a USB-C cable
- Phone chargers or cheap cables don't charge the laptop at all
- Charging works on one USB-C port but not another
- Charging works with the original charger but not other USB-C chargers
Likely causes
- CommonCharger doesn't support Power Delivery or isn't high enough wattageA phone charger (typically 18–30W) usually can't charge a laptop that needs 45–100W.
- CommonCable doesn't support the needed power or data specificationMany USB-C cables are charge-only at low wattage and can't carry a laptop's full charging power.
- PossibleWrong USB-C port used (not all ports on a laptop support charging)Some laptops have only one or two of several USB-C ports wired for charging.
- PossibleFaulty USB-C port or internal charging circuitPhysical damage or debris in the port can block the charging handshake.
What to do
- Confirm the charger is rated for Power Delivery at or above your laptop's required wattage (check the laptop's original charger label).
- Try the original cable and charger that came with the laptop to confirm a baseline.
- Test each USB-C port individually, since not all of them may support charging on your model.
- Try a different high-quality USB-C cable rated for 60W or 100W, since thin or cheap cables often can't handle laptop charging loads.
- Restart the laptop after connecting, since a stuck charging negotiation sometimes resolves with a reboot.
- Inspect the port for lint or damage, and clean gently with compressed air.

When to call a pro
If the correct wattage charger and a known-good cable still don't charge it on any port, the USB-C charging circuit likely needs professional repair.
