Monitor Calibration

I am trying to calibrate my home laptop LCD monitor using an X-Rite Eye One
Display 2 for digital photography purposes. After the calibration process,
the X-Rite creates a custom monitor profile and sets it as default. This
works fine until the computer is powered down. Thereafter, the old monitor
settings are displayed even though the display settings show that the
calibrated monitor profile is still set as default. I cannot get the laptop
to use the calibrated monitor profile. I've tried re-adding the profile
file, re-selecting it as default and rebooting but this doesn't work. When
the laptop is powering up, I can see the monitor appearance change three
times (original>calibrated>back to original).

My laptop is an HP Pavillion DV2000 with an Intel GMA X3100 display adapter.
BTW, my XP desktop has been calibrated without a hitch.
