Step-by-Step Repair
- 1
Test with a different charger and cable
Use a known-good charger and cable. Cables are the most common failure point. Try charging from a wall adapter rather than USB — wall adapters deliver more consistent power.
- 2
Clean the charging port
Use a flashlight to inspect the port. Carefully remove lint and debris with a wooden toothpick. Compressed air helps too. A clogged port prevents the cable from making proper contact.
- 3
Check for software issues
Restart the device. Check battery settings for any warnings or calibration issues. Some devices stop charging at a certain percentage to preserve battery life — check if this feature is enabled.
- 4
Try charging while powered off
Power off the device completely and then plug in the charger. If it charges while off but not while on, a background process is draining power faster than the charger can deliver it.
- 5
Inspect for physical damage
Look at the charging port for bent pins, corrosion, or damage. Check the battery compartment (if accessible) for swelling. A visibly swollen battery must be replaced immediately.
If That Didn't Work
- Faulty wall outlet or power strip
- Power management IC failure on the motherboard
- Corroded battery contacts
When to Call a Professional
If multiple chargers don't work and the port is clean, the charging port or battery likely needs replacement. Expect to pay $40-$100 for port replacement, $30-$80 for battery replacement.
