i contacted them already, they said it's over a year therefore it's out of warranty And it's very disappointed as this is only around 18 months. i have not had issues with other brands which i have had over the years. It seems ASUS not very stable and durable

Try this steps-
First, please check the connection and appearance of the battery/AC adapter
EC reset
Update and confirm BIOS / Windows packages / drivers with the latest version in your laptop
Reset the BIOS settings
Run Battery Diagnosis via MyASUS
Reinstall the battery/AC adapter drivers via Device Manager
