Laptop screen shuts down, Secondary screen OK

I would say it is your screen itself and\or the back light. Since it does work with a external monitor would suggest a signal issue. Is the laptop under warranty or do you have a shop close by that you use that could check the connections and the screen itself?

Thanks, I thought it might be the screen also. Any time I reboot the laptop the screen has strange colors, returns to normal but about 20% darker, then shuts off. The colors on the secondary monitor are normal. Connections are good.

Since the colors and brightness are not affected on the external monitor that shows it's not the graphics card having the issue. It is the screen having the issue. Common problem as laptops get older. It is possible to replace the screen but do so checking around with not only Dell but your local shop. Also check online for laptop screens as there are several there that you may be able to purchase a new screen from.

Please mark solved. don
