Right, but it's either the laptop monitor or your Windows... but probably the screen, as you mention this happens immediately, whereas I can see that others with white screen seem to experience a short delay before it happens, ie it hits when Windows starts loading.
To properly test your hardware, and unless someone has some better suggestions or you can find another solution, you should really create a new partition and try and install Windows (any version, but if you are doing this as a test might as well use W7) to that partition. If white screen still occurs in this scenario, then you have a hardware problem with the the laptop monitor.
Depending which Windows you have installed there may be some other things you could try before dropping the bomb on your setup -- given that you can access Windows using the external monitor, you could try uninstalling the driver, and also during startup hit F8 and try to boot in VGA/Low Graphics mode.
If installing a new copy of Windows works (ie the new copy has no whitescreen), but no manner of poking and fiddling seems to help with your current Windows, then the answer is that you should clean install Windows as this is likely to be less time-consuming and frustrating than trying to search and destroy any software-based configuration errors that may exist in your current setup, particularly given that these errors might simply be the result of data corruption potentially, for which the only real solution is to reinstall anyway.
