So I forgot my droid x at home today when I went to work and it was left plugged into my laptop usb slot. My laptop was turned off btw. It had 3 presets of alarms that naturally went off, and since I wasn't home to turn them off, it completely drained the battery of my phone. So I took my usb plug and plugged it into a wall adaptor and it was charging normally, about 30% into the charge I unplugged the usb and while on my labtop surfing the web I decided to charge my phone on my laptops usb slot again but this time it didnt give me any sign that it was charging, usually a notification comes on and gives me options to use the USB for, and I usually pick for charge only. So I'm stumped, I've looked everywhere on the phone but I cant find anything closely related to the USB. Can anyone help me with this little annoying problem? Thanks.
