The battery on my Nexus One was low so I had it plugged in to my computer to charge for a few hours whilst the wife and I were watching some TV. I just went back to the computer to see how far it was charged and my trackball was flashing but there was no power when I tried to wake the phone using the sleep/wake button. I unplugged it from the computer and tried to wake it again with no luck. I held the power button down to power cycle it and it shut off but after that I couldn't power it on again. I thought I'd try it in the wall charger and same thing. When it's plugged in to the wall there is nothing. No charging lights and no power. Before I phone HTC is there anything else I could try that I may have overlooked? Thanks for any suggestions.
