Chuwi minibook x not charging until completely drained

Dear Admin,
My Chuwi minibook x started having problems with charging a couple of weeks ago. It will suddenly stops charging with the battery light saying on or blinking. It will not charge until the battery is completely drained and recharged. This problem happens every now and then. Please, could someone help on how to resolve this issue? Should I update the bios? If yes, could someone provide me with the link to download the bios?
