What can cause this problem
Several faults can create the same symptom. The list below is a starting point for diagnosis, not a reason to order parts without testing.
- Damaged charger cable or tip
- Loose socket or broken mount
- Worn USB-C connector
- Failed battery
- Charging controller or input protection fault
- Liquid or debris in the port
Safe checks before repair
Protect important files first where the device remains stable. Stop after liquid, smoke, battery swelling, burning smells or signs of a failing drive.
- Bring the original or normal charger
- Inspect for obvious cable damage without bending it repeatedly
- Note whether charging changes with plug movement
- Check for heat or smell and stop if present
- Record whether another compatible port behaves differently
- Back up files while the laptop remains stable
Possible repair routes
The correct route depends on the confirmed cause, exact model, data requirements and whether a reliable repair remains economical.
- Charger replacement
- Socket or USB-C connector replacement
- Battery replacement
- Board-level charging repair
- Data backup before major power work
What changes the quote
A headline price cannot account for every model, part and level of damage. These are the main factors that need confirmation.
- Removable socket versus soldered connector
- Board-pad damage
- Battery condition
- Part availability
- Liquid or heat damage
Frequently asked questions
Can I use glue to hold the charger in place?
No. It can trap heat, damage the port and make proper repair harder.
Why does it charge only when switched off?
Battery, charger and board-level charging behaviour need testing; the symptom does not identify one part.
Can USB-C ports be repaired?
Yes, where connector and board damage allow a reliable repair.
Should I replace the battery first?
Only after testing confirms it is the cause. A charging fault can prevent a healthy battery from charging.
