I have an unlocked Focus that I basically use to just play XBLA games.
The other day it was about to die. I didn't feel like finding an outlet, so I plugged it into my iMac and walked away.
The next day I check it, and the battery is dead. It won't even turn on. I figure my iMac turned off and never charged it, so I plugged it into an outlet, walked back to my iMac and started using the computer. Then I see a message that basically says, "The USB device was drawing too much power, so it was disabled."
I go back to my Focus and it won't turn on.
The most I can get, randomly,is the Samsung screen and the dead battery indicator.
I leave it plugged in for 4 hours, come back and that's all I can get.
I hold random buttons, and I get a screen with a yellow exclamation point and it said something about 10 minutes. I'm sorry, but I honestly forget.
Now, I can't even get to the Samsung screen today.
