Although the design and function of this refurbished Dell chrome book is fantastic for the selling price, I discovered that the Up Arrow Key did not work. It was completely dead. I bought it to a trustworthy computer repair shop I know. To fix it would cost $100 because the entire keyboard would need to be replace. You can't replace just one key. So, I would only purchase this chrome book if you worked on computers, or have access to spare parts, or you know someone who could help you. My recommendation would be if you buy one, open a Key Diagnostic program (Keyboard Test Program) and check all the keys as soon as you receive the chrome book.
