So I just started up my ASUS laptop, and I saw how BatteryBar showed me an N/A text. I was confused why it told me that. I hovered over it, and it told me that the battery is completely empty. I looked at windows battery indicator, and it told me too that it was 0% not charging. I tried removing the power cord and the laptop turned off instantly. So now I know that the battery is completely empty. Yesterday, It was not empty. I made a battery report using CMD and I could be sure that it had some power in it yesterday. Also, the battery is not removable, so I can't try removing it and reinstalling it. The laptop model is ASUS X550ZE. Also, the battery wear level is 50% , but it was like that for a long time. Is there a way to fix this?
