Hi andrewm06,

I’d suggest that you update BIOS on your computer to check for issue resolution. Please enter your service tag # on the link below, then download the BIOS from BIOS section onto the system and install it.

If the system is already updated to latest BIOS then I’d suggest that you follow the steps mentioned below and check for issue resolution.

1. Switch off the computer.
2. Disconnect the AC adapter from the system.
3. Remove the battery from the computer.
4. Press and hold down the power button for 15 seconds.
5. Then connect back all the peripherals and check for issue resolution.

In addition, I’d advise that you load defaults in the BIOS. Please follow the steps mentioned below to load the BIOS to defaults.

1. Reboot the computer.
2. When prompted during POST, press the key to enter the setup screen.
3. On the System Setup screen, press the button.
4. Press the Apply button and exit to restart the computer.

I have updated the BIOS to the latest version and also followed your first suggestion. The BIOS screen is still invisible.

Regarding the second suggestion, as I mentioned in my previous question - the BIOS screen is invisible  - so I will not be able to load defaults.

If you can point to me various screens of BIOS in this versio, I can navigate and do the needful. My hunch is , after pressing F2, laptop does go into BIOS, but the screen is not visible. If I don't press F2, the laptop just boots up windows.

Hi Andrew,

I would suggest you to downgrade the BIOS to previous version to check if issue resolves. Please use the link below to download and update the BIOS
