I just did a clean install of vista on my newly received x200 and I am using the power manager 2. I noticed that when I switch power source(plug or unplug the power cord), the screen flashed once (got into black screen and came out). Is this normal?

yeah mine does the same thing. I'm not sure why that happens though
