I was charging a phone using USB that I had connected directly to the phone battery with naked wires which on that case dint charge instead I found it warm.
by the time I turned back to the Lenovo there was no display.
the reason am not sure if this was the problem is because I had restarted it after some windows updates that I interrupted while installing. it started well that I also double clicked windows 10 with intention of reinstalling it.
that's when it went of. I tries resetting memory all In vain
