When we turned off the computer yesterday, the screen said that there were 12 updates to be installed. So it proceeded to do this, and when it got to 10 completed, then nothing changed. It stayed on 10 for a long time (seemed like it was frozen on 10). So we unplugged the computer (having to leave, couldn't stay). Then we tried to turn it on again - and computer said that it hadn't been shut down properly. So now we don't know what to do? Any ideas about what next to do? (when this has happened to my own computer - same thing - gets frozen on an update installation - then I would unplug it and remove the battery to get it started all over again - and that always worked on my computer).
