When my P1510 arrived, the screen was in dire need of calibration (it was nearly 2 cm of the mark in the top of the screen).
This of course is not a problem: just run the software and calibrate it. But how does one calibrate the logon screen?
(it is also 2 cm off at some points, making the onscreen keyboard hard to use)
I have tried calibrating the 'administrator' account, but it didn't help. I have also tried the Microsoft tweakUI (one of the XP Powertoys): it allows one to copy mouse/keyboard settings to the log on screen, but it didn't copy the calibration...
