magnet has to have poles aligned left and right, in the correct
polarity. Alternatively you can do as you did, which is required in
manufacturing tests, and move the laptop around yourself. This is the
more correct way to do it, since it is also the worst configuration for

is probably a B2 model you are using. Give me the serial number and I
