Re: "Your mobe could charge your laptop"
"I complain because something happened to USB cables about a year after I bought my last mobe. They don't work with it. That was just 2 1/2 years ago."
I have no idea what you are doing, but I have ancient USB1 devices that work on USB 3 kit. I have no idea why you feel the need to rip and replace, as the beauty of USB is it is compatible.
My guess is you are using those shit 99p cables from eBay.
