My MiniBook M3 8100Y cannot use battery , only AC plug mode

Does anyone know how to fix/repair the battery charging fail issues?

My MiniBook M3 8100Y had been showing No Battery icon and Only AC plug mode now.

BTW, I can put the POWER BANK Power for short operated but quite not well use.

Best Regards,

Battery probably dead

Just buy a new one
