Toshiba Sleep-and-Charge Technology

Toshiba's Sleep-and-Charge technology is a USB power solution that was introduced with their 300 series notebook line (p305, m305, etc) that enabled the ability to charge/power USB devices while the computer is turned off. Normally, if a computer is on or in standby, it will have power to its USB ports. However once it is turned off they're unpowered. With Sleep-and-Charge you can still use the USB ports for power while the computer is off.
