Dell Inspiron 7720 Laptop - Battery 100%, turns off when not plugged in, have tried new battery

As the title says.

My battery is 100% charged, when i disconnect the power lead after 30 seconds or so my laptop powers off.

I bought a new battery today charged it to 100% and it does the same thing

Any ideas please
