Steps

Goal: Rule out adapter and port, then isolate battery or port failure.

  • Confirm the power adapter is connected at both ends and the outlet works.
  • Good: Adapter and outlet confirmed. Proceed to Check adapter and port.
  • Bad: Try a different outlet and adapter.

Check adapter and port

Goal: Rule out adapter fault and port issues.

  • Reseat the adapter. Inspect the charging port for debris and damage. Try a known-good adapter.
  • If a different adapter works, replace the original. If not, the port or battery may have failed.
  • Good: Adapter and port confirmed. Proceed to Power-cycle if battery is removable.
  • Bad: Port damaged or loose—call a technician.

Power-cycle

Goal: Reset the charging circuit.

  • Shut down, unplug, remove the battery. Hold the power button for 15 seconds. Reinstall the battery, plug in, and power on.
  • Good: Laptop charges. If not, reinstall the battery driver in Device Manager.
  • Bad: Battery may have failed—call a technician. If the battery is swollen, do not use the laptop—contact support.

When to get help

Call a technician if:

  • The charging port is damaged, loose, or sparking.
  • The battery is swollen—do not use; fire hazard.
  • A known-good adapter and outlet do not charge the laptop.

Verification

  • The battery icon shows charging when plugged in.
  • Battery percentage increases over time.
  • No damage to the port or swelling of the battery.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Adapter and port Reseat connections; try different outlet and adapter.
  2. Power-cycle Remove battery, hold power 15 sec, reinstall.
  3. Drivers and settings Reinstall battery driver; check battery limit settings.
  4. Call a pro Port damaged, battery swollen, or adapter confirmed good but no charge.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Laptop model and adapter specs
  • Whether a different adapter works
  • Port condition (loose, damaged)
  • Steps already tried

Is the power adapter firmly connected and the outlet working?

Loose connection and bad outlet are common causes.

Reseat the adapter at laptop and wall. Try a different outlet. Check adapter LED if present. Good: adapter connected, outlet works—check port. Bad: adapter or outlet faulty—try different adapter.

Yes No

You can change your answer later.

Is the charging port clean and undamaged?

Debris and port damage prevent charging.

Inspect port for debris, bent pins, looseness. Blow out dust. Clean and secure: try battery removal and power-cycle. Damaged or loose: call a technician.

Yes No

You can change your answer later.

Try a known-good adapter

Use a compatible adapter (same voltage, equal or higher wattage). If it charges, replace the adapter. If not, check port and battery.

Done

Remove battery, hold power 15 sec, reinstall

Shut down, unplug, remove battery. Hold power 15 seconds. Reinstall battery, plug in, power on. If still does not charge, reinstall battery driver or call a technician.
