Alternative Driver Method:
- Visit laptop manufacturer's website
- Download latest chipset drivers
- Install and restart
- These often include battery management updates
4. Check Windows Power Settings
Certain power configurations can prevent charging to preserve battery life.
Critical Settings to Check:
- Battery charge threshold:
- Some laptops stop charging at 80% by default
- Check manufacturer's power management software
- Disable conservation mode if enabled
- Power plan settings:
- Control Panel > Power Options
- Change plan settings > Change advanced settings
- Battery > Critical battery level: Set to 5%
- Battery > Low battery level: Set to 10%
5. Test with Another Charger
Determines if the issue is charger-related or laptop-related.
Charger Compatibility Check:
- Wattage: Must match or exceed original (65W, 90W, etc.)
- Voltage: Must match exactly (19V, 20V, etc.)
- Connector: Same size and polarity
- Test options:
- Borrow identical model charger
- Try universal charger with correct tip
- Visit computer store for testing
6. Cool Down Overheating Components
Thermal protection stops charging when laptop or battery overheats.
Cooling Solutions:
- Immediate cooling:
- Shut down laptop
- Remove from soft surfaces
- Elevate for airflow
- Wait 30 minutes
- Clean air vents:
- Use compressed air
- Blow out dust from vents
- Clean fan grilles
- Check thermal paste:
- If laptop constantly overheats
- May need professional reapplication
7. Run Windows Battery Diagnostics
Built-in tools can identify battery health issues.
Generate Battery Report:
- Open Command Prompt as Administrator
- Type:
powercfg /batteryreport
- Press Enter
- Open generated HTML file
- Check:
- Design capacity vs. current capacity
- Cycle count
- Recent usage patterns
Run Power Troubleshooter:
- Settings > Update & Security > Troubleshoot
- Additional troubleshooters
- Power > Run the troubleshooter
- Apply recommended fixes
8. Update BIOS/UEFI Firmware
Outdated BIOS can cause charging issues, especially on older laptops.
BIOS Update Process:

- Trackpad bulging: Battery expanding underneath
- Case separation: Gaps appearing in laptop body
- Excessive heat: Battery area very hot
- Rapid discharge: Battery dies within minutes
SAFETY: If battery is swollen, stop using immediately. Fire hazard exists.
10. Disable Battery-Draining Features
Some features consume power faster than charging provides.
Quick Wins:
- Screen brightness: Reduce to 50-70%
- Keyboard backlight: Turn off if not needed
- WiFi/Bluetooth: Disable when not using
- Background apps: Close unnecessary programs
- USB devices: Unplug external drives
- GPU settings: Switch to integrated graphics
11. Reset Laptop to Factory Power Settings
Third-party software can interfere with charging.
