I don't think those are errors per-say... I know that the network icon is always white -- standard color for all the system icons. I think that the X just means you're not connected via a physical connection since I believe to the right it, it shows your wireless connection. As for the battery... If you're having issues with it, I've read that sometimes the battery and monitor doesn't really sync up good at times and you can solve it by 'resetting' the meters by letting the battery run all the way down, turning the computer completely off and letting it charge up fully. Next time you start it up, the meter should be properly measuring the battery.
