It's not really practical anymore. I'm selling it as a collector's item. The internal battery seems to be working, but the main battery is completely dead. It loses power when the cord is unplugged. Please refer to the photos for the exterior condition. Feel free to ask any questions. Included: AC adapter Built-in stylus pen - Model Name: sigmarion III - Keyboard Type: QWERTY - Screen Size: Small - Interface: USB port - Color: Black/Silver - Features: Foldable design Thank you for looking.
