Hi all

I have a laptop with a broken screen.

I have attached an external monitor which has worked ok.

However, the other night I needed to shut down the laptop by holding down the power button.

Now when I turn on the laptop it does not recognise the external monitor (previously the external monitor would come straight on).

I have tried turning on the laptop on and shutting the lid straight away, pressing Fn+F4, hitting the windows sign and pp all to no avail. I'm wondering if these are not working as the computer did not shut down in the proper way and therefore it is stuck on an initial screen which I need to get off.

Any ideas?
