I've had my tf300t and keyboard dock for about 5 months now and it has performed fine until yesterday. I was looking up something on the net when the tablet just rebooted for no reason. It did this 3 more times. I did a factory reset and things seemed ok. Today, I power it on and noticed that it's not charging on the keyboard dock. The dock works fine but the tablet just won't charge on it. I read on another forum that there may be an issue with the SD card that I have in it so I took it out and restarted and it began to charge. I put the card back in and it still charged. I then restarted and the charging stopped. Now it won't charge the tablet at all.Any ideas? Do you think I should do another factory reset?
