I am using Windows XP Standard and Windows XP embedded on different machines.
They are deployed without monitors and without keyboards. They are also password protected.

When someone needs to access them, they will attach a monitor and a keyboard and login.
But sometimes the video does not come on at all.
Even if we reboot the machines with the monitor and keyboard attached.
It will show the windows splash screen and the monitor will go into sleep mode.

CTRL + ALT + F1 used to work when the computers were set to log in automatically.
But when we set it to ask for a user name and password CTRL + ALT + F1 doesn't work.
So we would need to log in blindly. We would put in the password, hit enter and hope we got it right or restart and try again.
So we know CTRL + ALT + F1 does not work unless you are logged into the machine.

The monitors connect via VGA/D-sub port and keyboards through USB.

Is there away to keep the video active even thought there is no monitor connected to it?

The machines need to be password protected and those accessing it might not be very computer savvy.


Thanks in advance.

IIRC...monitors have no impact on signals, other than to received them...while the absence of a keyboard will cause some systems not to even boot.

Sleep mode...is governed by system settings, not the presence or absence of hardware.

If you reboot with keyboard/monitor attached...and get no video signal...I would guess that you have a hardware problem...you may want to explore that in one of the hardware forums here at BC.

FWIW: There is no Windows XP Standard, maybe you mean Embedded Standard.
