The laptop is perfect, but there is a tiny blue line that appears during black screens in the middle of the screen when watching TV shows movies as seen in the photos. Doing anything else on the laptop that line does not appear, watching YouTube,twitch etc,browsing. Only dark scenes show the line. I have tested with YouTube,Twitch , and football even, and the line doesn't appear. I'm not sure if it's hardware or software related. I have watxhed tv shows and mpvies feom laptop and for most people it wpuld be a non issue. I purchased this laptop used, and it does have cosmetic damage, so maybe it was dropped. As it stands though it's fully working with zero issues except for that. It's fast and loads everything without issues. Comes with charger and will be wiped before purchase. No swaps or time wasters. Refurbished, it sells for 429€
