There are a couple of reasons you may not be able to see BIOS.
1. It could be that your HDMI connection doesn't kick in until it is past that point. Which might be resolved by using a monitor rather than a TV to view through (assuming the attached display isn't working).
2. The computer is set up to start with Fast Boot. If that is the case, then you would need to turn it off to be able to access the BIOS.
NOTE: It could actually be both of the above are needed to make it work.
You will need to disable "Fast Boot" from the power button menu. The power button can be used if you encounter Fast Boot problems.
1. Make sure the laptop is turned off. Not in Hibernate or Sleep mode.
2. Press the power button and hold it down. The system should emit three short beeps from the speaker, or headphones if you have them plugged in.
3. After the beeps, release the power button 'before' the 4-second shutdown override.
4. The power button menu should now display.
5. Press F3 to disable Fast Boot and you should be able to access BIOS now.
To enable Fast Boot:
1. When the laptop boots up, enter the BIOS setup by pressing "F2".
2. Now go to the "Boot Configuration menu".
3. Choose the "Enable Fast Boot".
4. Press F10 to save the changes and exit.
