This is really starting to annoy me. My laptop won't shut down properly. If I shut it down from Windows it goes to a black screen and lights and fans are still on, This happens whether I'm on power or battery. If I shut it down from within Ubuntu then it hangs on the **bleep**down screen with 3 of the 5 dots changed colour.
It will sit in either of these states until I hold the power button down to kill it.
I've updated the Bios and reset it to defaults and still it won't power off properly.
I've also noticed that the fan seems to be running full all the time but it's not getting particularly hot.
