HP Docking Station Elite 8440p Black Screen After Boot Up Windows XP

This is the latest solution

The latest HP 8440P bios F0.B has been released and fixes a number of issues with the 8440P laptop. I’ve tested this on my new laptop with great success.

The fixes include:

•    No more black screen when starting the machine on a docking station (you don’t have to disable the serial port anymore in the bios)
•    Extremely noisy fan when you bring the machine back from sleep / hibernation
•    VT problem (when you enable VT it's not possible to do a warm reboot)

The update should be performed from a USB stick not from within windows:
