My Asus battery is suddenly dead, or is it?

Yesterday I unplugged my AC cable and my X550Z laptop died. When back on, indicator showed 74 % battery and not charging.
Since it is an internal battery, I opened the case to see if something had disconnected, and everything looked fine.

Today, after only being able to turn it on with the AC cable, the battery indicator says 0 % and not charging.

Before buying a new battery (or taking it to Asus service), is there any way I can test if this is caused by the battery itself or by a connection?

Battery was working fine until it suddenly died (it came with the PC, which I bought new six months ago).

Hi,

Here are some test you can run just to be sure if it's the battery or the AC adapter.
- First is to test your AC adapter is it's working properly.
- Remove the battery off the laptop then boot it up with just the AC adapter connected and see if it will work normally.
- If it does, turn it off then try putting the battery back in and try booting it up again with the battery and AC adapter.
- If it's still not charging that means the problem lies on the battery itself.
- If you have a different AC adapter try it as well and see if the same problem will persist or not.
- Last troubleshooting step you can try is to uninstall/reinstall the "microsoft acpi-compliant control method battery" from Device Manager.

I performed the tests:
-Laptop runs well without battery, and the system correctly recognizes there is no battery attached (I suppose this means the battery connectors work fine?).
-Unfortunately I have only one AC adapter that fits the laptop.
-Uninstalled the driver and nothing changed.

Something I noticed: the PC being off, battery connected and AC plugged in, the orange battery indicator lights for a second, then turns green and fades into orange again, every minute or so. Does this mean anything other than the battery doesn't work?
Thank you for your help.
