laptop screen not detected after moving image from desktop

"Desktop image" isn 't very clear. My first thought was you meant an image of your desktop and I couldn't see why a jpg file would cause your screen to not work. Are you saying you moved a cloned drive to the laptop?

The fact that the screen only works in safe mode would probably mean you haven't installed the correct video drivers.

Moving a windows drive to a new machine and expecting it to work correctly in all instances is dreaming on a grand scale. The registry is a complicated place and minor references to hardware that is no longer available can cause problems. Simply removing hardware items using device manager won't guarantee the removal of all registry entries that reference that device.

You could spend hours trying to find the problems or you could spend a few less hours and just do a clean install. From experience, I know that trying to simply upgrading windows won't fix the problems of moving an existing windows drive to new hardware. (But my problem was with HAL and trying to make ACPI work correctly. A minor annoyance since it always required pushing the physical button to turn the machine off after a software shutdown.)

Welcome to A2K!

Not sure I completely understand your question, but try right clicking on the desktop image you can see on the external monitor and selecting "Properties". Select the "Settings" tab and you should see a view of your monitor configuration. There might be something here you can do to activate both the LCD and the external monitors. One other thought: disconnect the external monitor. If the laptop is defaulting to only display on one monitor, it might be set up to choose the external monitor preferentially, but will default to the internal LCD if no external monitor is present.
