Laptop turns off Power and battery LED orange blinking

Hello,

Before I had problems with my battery, sometimes wasn't charged fast enough so my Toshiba laptop was turning off, so now I work without battery. Lately my laptop is turning off suddenly from time to time then Power and battery LED start blinking with orange color. I don't think the problem is the heat cause it used to get hotter and still work fine. After this the only way to start the laptop is to unplug the power and plug it again and turn the laptop on.

Please help me fix this.
