Lenovo Boot screen not displayed on external display.

Hello,

I have Lenovo G505s laptop with broken screen so I use external display. Earlier, this display use to show Lenovo splash screen and boot screen on startup. Recently I updated my BIOS to recent version. Since then I am unable to see splash screen. I directly reach Windows logon screen.

 

I want to reach BIOS but it isnt displayed. Please help.

 

Thanks.

System> Windows 8.1

Model> Lenovo G505s

Re: Lenovo Boot screen not displayed on external display.

Hello,

Somehow I got to make it work. Its easy and I thought I will share with you all.

 

All I did was change the Boot mode from UEFI to Legacy and it started showing boot scrren on external monitor. Again this was tricky and had to be done blindly.

 

Here are the keystrokes:

First shutdown your laptop.

Now press Novo button (small button besides power button) to turn on laptop and follow keystroke as follow:

'down arrow' 'enterkey' 'right arrow' 'right arrow' 'right arrow' 'enter key' 'down arrow' 'enter key' 'right arrow' 'enter key' 'enter key'

 

Now your laptop would reboot and show boot screen on external monitor.

 

Cheers!!

Does anyone know how to do the same for t430? I do not want to press random keystrokes blindly. My screen died as well.

I have Lenovo G510 with broken screen - now use external monitor on D-Sub.

Now I have problem with Windows and I need to run UEFI/BIOS - how do it ?
