My sister's Asus VivoBook X540NA laptop, which is barely a year old, used to run fine on battery as well as on AC power until a month ago, when all of a sudden an issue came up. The laptop dies immediately when unplugging it from power. I checked around in windows power settings to change anything peculiar, but everything was alright. I ran the windows powershell command to check the device's battery health, but i did not know what those numbers meant. I'd like to know if theres anyway i can fix this issue through software before giving it to a service centre. Thanks in advance!
