Hi, I have an Asus X401a laptop that sometimes gets stuck at 82% charged. I am visually impaired so I cannot see the lights for if it is charging or not. I have listened to the charger's transformer and all sounds normal. Also, when I check in the notification tray it says plugged in, charging. I am very tetchy when it comes to laptops having problems and am sceptical to use my machine plugged in without battery.
