Instead, with only a bit of innovative idea, a simple tweak will transform it into a great selling feature that suits consumer market requirements. Key takeaway here – it is not always necessary to invest huge cost and development effort to come out with great features product. This is understandable as no peripherals power can be maintained when it enter deeper sleep states. Anyway, the laptop units will need to be plugged to external power supply (even in off mode) in order to get the sufficient power supply to charge external devices. Some of the models include U400, M300, A300 and P300 but not limited to other models in short future. The solution may not be tough to be implemented but surprisingly Toshiba is the first one that thinks of integrating it into its new Satellite laptop series. Named as Sleep and Charge USB port, it is similar to conventional USB 2.0 host port but with additional capability of charging external devices even the laptop is in power off mode. Now, there is a better solution from Toshiba to be able to continue the device charging even the laptop is put into hibernate or shut down mode. They can even use and charge the device at the same time, thanks to the variety of power settings. The models include the Satellite U400, Satellite M300, Satellite A300 and Satellite P300. This is not always practical as you will end up drawing more current from both devices which is not in need. But, the sleep-and-charge USB port is sure to give us a sound sleep and also charge the device at the same time. However, in order to keep up the power of the devices, there is a need to maintain the laptop in power on condition, regardless if you need that to be on or not. Besides, it is useful for charging any portable device by simply sourcing current from the motherboard for continuous operation. USB 2.0 port on PC or laptop can be used for data synchronization and files transfer.
