Thinkpad G40 reboots when connected to new projector

[BoilerIMS]

Hello,

I have an interesting problem, likely related to Windows XP, with my "new" used G40.

Whenever I connect the thinkpad to a new projector through the external monitor port, Windows XP reboots. By "new projector" I mean a projector that has never been connected to the notebook before. If I later reconnect to the same projector, the thinkpad does not reboot.

Is there a way to disable this reboot procedure? I attend conferences where I regularly have to plug in to new projectors and often cannot wait for a reboot.

Thanks
