Screen/Display no longer shuts off

Thanks, I was even happier, I just didn’t want to trash out the laptop.
My next project, would you want me to post it as a new topic?
I have an adapter so my plethora of hard drives can be swapped out with my CD/DVD drive. I would like to format them all, so I don’t need to go through that partition nightmare again. Is it a terminal command?

If you’d like format your hard drives from command line, the above mentioned fdisk or gdisk (if you use GPT) are the tools you search for.
