I've got a friends laptop here, it's a Dell Inspiron 1545.
Here's what's happening with the screen:
I plugged it into a spare monitor and it works fine there, so that rules out a graphics fault I assume? I want to make sure that it is the screen and there's not something else that could cause this to happen.
Also I noticed this in the bios:
It says unknown device and native res isn't listed?
All working fine on external monitor:
Any ideas? I want to make sure it is the screen before saying it is and spending ~£60 on a new screen.
Many thanks.
