Once I forgot to shut down my Dell Laptop and it run out of the battery. Then connected the battery to it and tried to start computer. But I did not start. I think it did not even boot. So I tried to install another OS but I could not. I can not even start any virtual environment. Basically my Laptop is not working and when I try to restart it most of the time it shows black screen with a cursor. And rest of the time some messages like "manufacturer's area error 67..." and stuff like this. Please can anyone help me with this.
