Won't charge despite rebooting

ocwaveoc

I have a 3000x with firmware 1.8.9. It once failed to charge so I found out that rebooting by pressing the button with green circle under the lid and "info" button simultaneously reboots the unit and allows you to charge. It worked. But, now it won't work. Actually, I'm not even sure it rebooted this time since it doesn't even turn off for 30 seconds (which it did when I reboot was successful).

Any idea on how to get it charging again?

Thank you.
