Hi,

I have a motherboard from an Envy 17 laptop (HannStar J MV-6 94V-0 E89382): it has CPU and RAM installed and is connected to a k/b and mouse by USB and to a monitor via the HDMI socket. The rest of the laptop, including screen, is absent. I can start it by shorting two "powerboard" pins and the fan activity and k/b light suggests that it boots, but there's no video signal to the external monitor, so I can't see what's happening. I have good reason to believe it did work in this configuation before I got it. However, in the course of my tinkering I disconnected the CMOS battery, so I guess the BIOS settings have reverted to defaults. The person I bought it from says this is why there's no video via HDMI - he says that needs to be (re-)activated in the BIOS.

First question: can it really be the case that HDMI is disabled by default?

Second question: can anyone offer a sequence of k/b keystrokes from bootup that will let me enable HDMI without being able to see what's going on?

And just to muddy the water further, I have no idea what the  BIOS version is.

Any other ideas/suggestions?

Thanks in anticipation.
