You're not a only one. Read a recent thread https://www.cnet.com/forums/discussions/low-disk-space-on-empty-laptop/ for the solution found by someone else.
I am trying to factory reset my ideapad but it says I need to free up more space in my hard drive. It only has a 32 gb HD and I’ve already freed up as much space as I can through uninstalling programs and such.
How can I get it to reset?
