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.
This should get you in so you can then check BIOS
If that doesn't work, try this
1. Power off the laptop.
2. Power on the laptop.
3. As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off.
4. Repeat this process a few times until you see the "Preparing Automatic Repair" screen.
5. Now you want to let the laptop boot to the "Automatic Repair" screen.
6. Click "Advanced Options" and then select "Troubleshoot".
7. Here you want to select "Refresh your PC", if you do not wish to erase data, or "Reset your PC" to erase all data and restore your system.
8. From here just follow the screen instructions until the recovery is completed.
NOTE: You will need to get into the "Advanced Options" in order to get the "Refresh Option". This choice will keep your data, but any programs installed will be lost.
Do not do a "Reset" as that will wipe all data you have on the laptop.
