I go on my computer today and found out that it has no battery left (which is always odd since I always charge it). And when I investigate it further, I suddenly have no internet connection (I have to reconnect it with the server), things with plug ins such as Pandora aren't working (and Gmail chat), and my computer clock has been reset to December 2000...I have no idea what happened. The most annoying thing is regular websites (like google for example) wont let me go in unless I "certify" it. I don't know what could have caused this, how do I turn it back to normal? I tried using firefox to only have the same result. And how do I get rid of the certification?

And any thoughts on what could have caused this?
