At the end of December 2020 I bought one of these refurbished from a third party (not Amazon Renewed). So I spent just shy of $400 and have had it a total of sixteen months and one week.Overall I like the computer okay, although I'm not nuts about Windows 10. Once I got the hang of it, the comp has served me well enough, but I've been giving serious consideration to replacing the OS with Linux.But the reason for only two stars is what turns out to be a well-known flaw in the computer's physical construction.Not even a year and a half since purchase and, when I went to close the lid tonight, there was a loud snap and I discovered that the left-hand hinge broke. I found one of the tiny screws laying on the keypad and the other rattling around near its designated location. But even worse, the corner of plastic frame around the screen was bent almost to the point of breaking off.I'd noticed that hinge was stiff right from the get-go, but I never anticipated it outright breaking. I have never treated this laptop roughly. It sits on a board that I use to move it from a table to my lap, and I always open and close gently it using both hands.This seems to be a moderately difficult repair I can probably do myself - if I can find a hinge. I'm sure not going to pay someone $300 to do it for me. Not sure if I can fix the bent plastic corner though.I realize this is a refurbished computer, so the company I bought it from is probably blameless. But Lenovo sure isn't. I was even more irritated when I found a lawyer's website that specifically spoke of Lenovo being abundantly aware of their faulty hinges since 2008 and never doing anything about it! For the record, it's usually the left hand hinge that breaks. Why is anybody's guess.Apparently I was lucky it didn't damage the screen - as has been known to happen according to several comments from a consumer reports site. And those were brand new from Lenovo. I'm also lucky that the computer is okay otherwise -  as long as I don't close the lid.For the record, I bought this comp to have something to use until I could get another refurbished Lenovo fixed. That too has something to do with the hinges. Specifically the wire that connects the system to the flip up screen. They run said wire through the hinge so that opening and closing it causes the wire to wear until the screen won't display if you open it too wide. Or worse yet,  the wire breaks outright. That's a repair no one advises you to attempt yourself. Oh, and half the keys don't work unless you really hit them hard (several times).So beware when thinking about buying one of these Lenovo laptops - new or refurbished. I was a dedicated IBM user until they sold out to Lenovo. I foolishly thought Lenovo would keep up to IBM's high standards. Apparently I was wrong.
