I was using this for accounting, but I'm selling it at a low price because I bought a new one. Operation confirmed. Initialized. You can use it from the initial language settings when you turn it on. ⚠ The right arrow key on the keyboard is missing, but it responds when pressed, so please consider purchasing only if you don't mind. - Brand: TOSHIBA - Model Name: Satellite Pro S500L Series - Model Number: PSSNU-021X1 - Accessories: AC adapter - OS: Windows 7 Thank you for looking.
