I do not know what to do. Why won't my laptop turn on?

Question

Batteries

Help, I connected an old usb hub at home and put power into the hub (I didn’t have to do this) without thinking, the laptop immediately passed out and stopped responding to anything. I pulled out the battery, waited, tried to turn it on without a battery. Nothing helps: C. Beech model Asus x55c. even if you connect that hub to a beech (when power is connected to the hub), then the battery type lights and something else start blinking.
