Identification and Background Information
The Toshiba Portege M400 is the first convertible tablet PC to have Intel's Core Duo processor as an option.
It has a biometric fingerprint sensor, which served to provide an easy and secure way to protect the information stored on your laptop.
Also like other tablet laptops, it has a stylus which serves as a mouse and touchpad, when the screen is moved to cover the keypad.
On the bottom of the laptop on the right there are two stickers for identifying the Toshiba Portege M400. There is one for the serial number and another for the product key: CHYDH-K42HB-7K247-CR6QP-TMRVQ.
