1. Low Battery: The most common reason is a low battery. Check the battery level indicator or plug in your charger to see if the light turns solid, indicating charging.
2. Faulty Charger: A damaged or malfunctioning charger might not provide enough power, causing the light to blink. Try using a different charger to see if the issue persists.
3. Loose Connection: Ensure the charger is securely plugged into both the wall outlet and your laptop. Wiggle the connector slightly to check for loose connections.
4. Battery Not Detected: The laptop might not be recognizing the battery. Remove and reinsert the battery to re-establish contact. Clean the battery contacts with a dry cloth if necessary.
5. Overheated Battery: If the battery is too hot, it might enter a protection mode, causing the light to blink. Remove the battery and let it cool down before reinserting
6. Outdated BIOS: In rare cases, outdated BIOS firmware can lead to battery charging issues. Check for BIOS updates from Toshiba and update if available.
7. Hardware Malfunction: Internal components like the charging circuit or battery itself might be malfunctioning. This is less likely, but consider professional repair if other solutions fail.
8. Dust Buildup: Dust buildup in the charging port or battery compartment can interfere with connection. Use compressed air to carefully clean these areas.
9. Calibration Issue: The battery might need recalibration to accurately report its charge level. Consult your Toshiba manual or online resources for specific instructions on your model.
10. Third-Party Battery: If you're using a non-Toshiba battery, it might not be compatible with your laptop's charging system, causing the light to blink. Consider using a genuine Toshiba battery.
