The T470s laptop I received had one of the internal batteries (and screws for it) removed, and there there had been no indication it would be missing this factory option in the product description. Presumably it was bad when they tested it so just removed it and hoped the customer wouldn’t notice. Also has damaged LCD, presumably from pressure damage at some point, so there are some vertical white streaks from backlight bleed through visible in upper right when viewing dark images/background. Otherwise the unit arrived very clean and well packaged, the Windows 10 install was clean and functional. Upgraded it to Windows 11 via bootable ISO without issue.
