KIANO Laptop Issues: Keyboard, Touchpad Inoperative, USB Unresponsive - Need Assistance!

I'll start from the beginning. When connecting the pendrive there was no reaction from the laptop. He couldn't see him. I tried to do something about it. Unfortunately, the internet doesn't always help and I had to remove some keyboard and touchpad drivers because nothing works. Only the power button, which doesn't seem much, because I can't even turn off the laptop. I connected keyboards and mice via USB, but none of that. I do not know what to do. No key combinations help. Help!

Hello. Hold down the Power button should turn off.

The battery went down, the laptop turned off, plugged in, turned on and everything returned to normal. In addition, the pen drive works. Pen works on other computers only not with me.

Insert it into the USB port, enter disk management and check if it is visible.
