Try downgrade the BIOS and check and then update the BIOS - and reinstall the chipset drivers from the same site. 

Restart and press f2 key on startup to enter BIOS - check if the backlit works in BIOS environment.

Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.

If the system is under warranty, write me a private conversation with the service tag and your contact details.

Keep us updated.
