Hi
I've contacted by HP Support yesterday. Was told that they try to avoid Mainboard swap. As an HP Partner, i was asked to send a few information (Build Order, Feature Bytes, screenshoot and Full HW logging).
I suppose, according to their question, that HP support Tool is no longer offering this 2.46 bios Upgrade while it's still on the Website.
I hope they will correct this and provide us a good bios in the next days.
Fortunately, this PC is on site and not sold to one of our customer.
