I am new to this forum and i have come seeking your help.
I have a Dell Inspiron 9400 with an ATI Mobility X1400 graphics cards which isnt being recognised now that i have installed Windows 7 x64, after doing some searching on here i see this is common problem. However, my problem doesnt seem to be covered.
As Dell dont support the card anymore because it is so old, i tried using a Vista x64 driver
and updating it using the device manager, this did not work. I then tried the mod tool method found at Mobility Modder - ATI Version, Install the Latest Drivers on your ATI laptop
and this worked, except there was one problem, my screen was no longer backlit. If i plugged in a second screen i had a display again and the X1400 was listed in the device manager instead of the Standard VGA, i also had aero capabilty and higher resolutions.
So in summary, i can get the driver updated and have higher resolutions and aero, but my screen goes black and can only be seen if i shine a light on it or i plug in a second screen.
