This is a Lenovo ThinkPad X270. It was working normally until recently, but I'm selling it because I've upgraded. It's been customized in various ways, so it might be useful for parts. The main components are as follows. Please note that there are scratches on the top cover and screen, so please check the photos for the condition. Storage: Replaced with NVMe (1TB FPI1TBMWR7) Display: Replaced with FHD *There is one scratch on the screen Wi-Fi: Replaced with Intel AX210 (Wi-Fi 6E compatible) Mobile: Added EM7430 (4G LTE compatible) Fingerprint authentication was standard Free shipping, and I will ship quickly. Thank you.
