this IdeaPad 510-15isk of mine the built-in screen is defective so i attached a VGA monitor to the VGA port. i learned somewhere that when a laptop senses, on bootup, that there is an external monitor connected it should send its display to the external device. my laptop doesn't do that and instead it uses the built-in display which i cannot see because it's defective.
i also try to get into the CMOS settings using that Novo button but it since it shows the display using the built-in LCD screen i am unable to check nor configure the CMOS to direct all output to external display (which i'm assuming is controlled by the CMOS).
since finding how to goto the CMOS settings on this laptop (that Novo button is too small is not well labelled) i thought there might be some hidden feature that would allow me to force the display to go to the external device. btw, the F10 hotkey that is supposed to toggle the display output doesn't do anything.
appreciate any help.

Thanks for using the Lenovo forums.
I belive if I know correctly, the only way to "force" the display to use the VGA/HDMI connections, is to disconnect the laptops main display from the motherboard, however, I would advise against this option if you are within warranty and to contact the support line for a possible service instead.
If you are out of warranty, and are comfortable with opening up your unit, you should be able to use your manual to find how to dissassemble the unit safely and disconnect the display module.
Hope this helps, let us know how you get on.

something else for you to try. Start the notebook and when you know it should be booted to the login screen press and hold the Windows key whilst you press the "p" key, release them and press the arrow down key once followed by the Enter key, hopefully you will have selected to duplicate your internal display onto the external one.
