Hi my laptop is a 7559 Dell Inspiron 7000. It is impossible to access the Bios with any computer function key. I think it may be a new "security" mode of Windows 10. It can be accessed from within Windows but some features are not accessible, such as rebooting from USB, for example. I had the misfortune to choose the "Legacy" option instead of "Uefi" in the attempts and this cost me dearly. I had to take the laptop apart and unplug the CMOS battery to go back to a BIOS reset. An absurd thing because the average user would have thrown the laptop in this case. I don't understand how this is possible!
I invited a problem by updating my bios today on dell 7559 and now I am unable to turn on my laptop. If I power it on, only the keyboard light turned on but no screen light or so. I tried to reinstall the main battery and ram but nothing happen. Actually my bios update stop in the middle and I had to force restart my laptop, now I am in deep trouble, can you please suggest that what should I do to make it work again. I see nothing when I turn it on, no F2 or F12. Please help !!!
Ciao, As I wrote, you have to take apart the laptop and disconnect the CMOS battery to go back to a BIOS recovery. For me it was the only way to reset the laptop. But you have to open the laptop and take apart.

You need to post your model computer. Tap F12 as soon as you reboot without waiting for any screen. Keep tapping to get to the Boot Menu.
