1.45 is actually quite a lot of difference. CRTs typically range from 2.2 to 2.5, and it's all multiplicative, so 1.45 represents about triple the difference you'd normally see between different monitors. Since your image is composed entirely of midtones, it's exactly the kind of thing that is most sensitive to errors of gamma correction, because shifting midtones destroys the contrast.
Try creating an image with several very pale grey shades - if it then looks *more* contrasty on your PC, then it's the gamma rather than the contrast making the difference.
Anyhoo, this is just a suggestion - if you can find an "assumed gamma" setting anywhere in your OS or image software, you might be able to deal with the problem without having to mess about changing the brightness of your laptop (and thereby makeing everything other than this icon too bright).
