I have the Toshiba satellite radius 4K edition laptop and it's just barely a year old. I went to go unplug the power chord yesterday because it was fully charged and it immediately turned off. I then tried turning it back on without the power chord in but it would not turn on. So now it only works with the power chord in. I haven't had an issue with the battery until now. Anyone have any ideas on how to fix this? It's not an easy removable battery, I'd have to take off the bottom of the laptop.
