Acer V15 Nitro VN7-592G wont turn on without charger plugged

After I removed the cover and clean the fan, put it back together, now my acer wont turn on without charger plugged. Its turning on OK when plugged, but once I unplug, the laptop turn off right away.
The battery is detected and shown as fully charged. The charging indicator is blue when plugged, so everything looks ok when plugged. Any idea why?

I have tried to unplug the battery cable, then press power button 10s to reset it, but the problem still persist. Please help, it was ok before I remove the case. Considering I just open the case and use air to clean it without doing any other thing, and put it back together again, wondering what could go wrong. I have ensured all cable already plugged as before.

There should be a button similar to this on the motherboard:

This button may not be pressed properly. Put some layers of electrical tape to press the button:

Good morning hudarsono !

Check the power interruption button.

The interrupt button not being pressed correctly may generate this problem.

There is a power interrupt button:

If it is not pressed down or the case is misaligned, errors may occur.
Check the same and use something like a layer of insulation tape to force and press this button correctly.
