For the last few days, the orange light on the charging port has been blinking on and off.

At first, the battery charged when the light was orange, but today, it's not charging at all, and the orange light is nowhere to be seen.

Any ideas if it's a battery, charging port, or charger problem? What should be my next move?

PS: the laptop has no battery now and is off.

Welcome to the Community Valia,

I'm sorry to hear about the issue you're experiencing with your Lenovo LEGION Y530-15ICH. It could be a problem with the battery, charging port, or charger. Here are a few steps you can try:

1. Try a different charger: If you have access to another charger, try using it to charge your laptop. If it works, then the problem might be with your charger. If not then check the integrity of the charger itself following the guide here on the hardware manual (page 21 Checking the AC Adapter).

2. Check the charging port: Look closely at the charging port on your laptop. If you see any debris or damage, it might be causing the problem. Try moving the ac charger end also like looking for sweet spot and observe. This can indicate issue with the dc in port. 

3. Reset the battery: Unplug the charger, turn off the laptop, and then remove the battery if it's removable. Press and hold the power button for about 15 seconds, then reinsert the battery and plug the charger back in. Turn on the laptop and see if it starts charging.

If none of these steps work, I recommend contacting Lenovo support for further assistance. You can submit a service request for technical support here. Also, you can check the warranty status of your product here to see if the repair might be covered.

I hope this helps, and please let me know if you have any other questions.

Best regards,
