Laptops display stays blank

[audris]

Hi,
My dads laptop(Lenovo thinkpad e555) crashed while opening a video. Now it just stays blank. No beeping sounds or anything. I did everything I found that could be helpfull - the 30,1,2; external monitor; ram checking(switched in checked the ram module in a different laptop, switched it between different ports). Tried powering on and closing the laptop and opening it. Tried the boot reset with windows key and b plus power. So if I'm not mistaken my motherboard is fried? I can try to connect the dedicated graphics to the display rather than integrated graphics? Or I have to take out a coil that gives electricity to the dedicated card(I found a video on youtube but I am a bit sceptical about this one.) So any thoughts guys/gals?

Thanks!

If it wouldn't work on an external monitor either, then your GPU may be the problem, which yes could mean the motherboard needs replacing.

Is it worth to try to disconnect the connection to dedicated graphics on the motherboard and try to boot the laptop then?

Different devices, different reactions. I can't say in all honesty. It is up to you.

UPDATE: The laptop was brought to repair shop where it got the bios reprogrammed and now it's working fine.
