Now i'm unable to get to the BIOS by pressing the F2 key or get to the BIOS upgrade screen by the F7 key. The Intel NUC splash screen wait for about a second and instantly the Linux boots without responding to any keyboard actions. I've tried with both a wireless and wired keyboards.
I search around the forms for this issue and found couple of threads indicating an issue with the monotor. I'm using a HDMI cable to connect directly to the Samsung TV. The problem with "not accessing the BIOS" issue was never occurring before i had problem with the power button. Not sure if both the issues are linked.
Ay ideas on how to access the BIOS menu?
