My power jack on my N800 is toast. It just wore out. The little pin in the middle of it broke off. I did the mod where power is routed from the USB to the power jack (installed the jumper) but it doesn't charge up at all really (I checked and the usb puts out 5 volts and the charger puts out 6.3 volts). The tablet really needs 6.3 volts at a decent amount of current to charge these batteries. I could really use a replacement power jack. Anyone know where I can get one for a reasonable amount? It's a snap-in; I can easily install it if I can get one. I am currently recharging using an external charger I got off ebay.
