Hi all, my customer has a Dell Inspiron 8000ut.

The problem is that, when running on the power adaptor only, the screen goes dark.

If you remove the power lead and run on battery, the screen is perfect.

I have tried a different power adaptor, updated the Bios, installed the latest driver, dismantled the screen assembly and checked for loose connections but it has made no difference.

The screen is perfect when using an external monitor.

Could the inverter cause these symptoms?

The screen is an IBM ITUX97E
