Herobook (CWI532) Cannot Energize

Several days ago my laptop suddenly turned off when I am using it.
After that, the laptop cannot be turned on anymore.
At first, the blue light indicator still turns it on when I plug it on the charger.
I tried to turn it on again and it starts to booting but it suddenly turned off again.
Now the blue light indicator stays off even when I plug it on the charger.
What happen with my laptop? Is it a factory defect or something else?
The model is Chuwi Herobook CWI532
