Hey there!
I got my laptop about 5 months ago and not long ago,some dark spots appeared on my screen.These things appeared from nowhere,and since the screen had no contact with anything really,I don't know that is this.I tried searching on the internet if people had similar issues and was only able to find this
The pictures are in the BIOS,so it is not a software issue.

They can be hard to see in the pictures,but it is really noticeable in person.
(Laptop:Lenovo Ideapad 530s)
Thanks for the help,
Alex
