In our previous article, we mentioned that it is possible to charge your new iPad via the USB ports on my HP Notebook. This is accomplished by installing the USB power boosting driver which was made available by ASUS. With the driver installed, and system rebooted, you can now charge your new iPad using your notebook. It will charge but it is definitely is not as fast as the power adaptor charge which outputs 2.1A.
Below is a video to prove that it works on my 1st generation HP ENVY 14 notebook.
