I don't mean going into Sleep or Hibernation. It just suddenly cuts out while I'm reading my online newspapers at night (which is when I use the battery, the thing is connected all day, when I'm working). This takes around 3-4 hours of just web browsing, nothing else. And when I connect it to the docking to get it starting again, the battery will show around 34 %. But it still won't power up withoug a power connection. Anybody knows what the heck is going on here?
