lenovo G570 bios password

2016-06-20, 3:59 AM

Hi G570/575 Users

The LCD of my G570 (model 4334) is dead black. I have to use an external monitor which is connected to the D-sub (VGA port)  to view the screen. However, my Window 7 is corrupted and I need to reinstall the OS. But the boot menu does not appear on the external monitor, thus I could not change the boot sequence to make the DVD as the first boot device(the HD is the first boot device now).
I was wondering if someone could help me the keystrokes needed to do the following:

1. The keystrokes to make the external monitor display the boot menu, save and exit. If this not possible, then
2. The keystrokes to change the first boot device to DVD, save and exit.


Thanks a lot.

Yiping

Hi Yiping , 

 

Welcome to the Community Forums. 

 

You can try turning the pc on using the novo button .

Else if the display cannot project , you may have to blind map it , step by step .

It would be using InsydeH20 , initially use Novo button to turn on. 

2nd option to choose BIOS option so down arrow once.

As it now goes to the BIOS main tab by default , 4 tabs to the right so it will be 3 left arrow .

Follow thru with this example.

 

Update us how it goes.

 

Regards

 

*** edited note for additional link ***

 

You can use this BIOS simulator for G570 to accurately map the step.

Thanks you very much for the reply. Sorry that I didn't get time to try until today. Thiswas what I have done:

1. Use the Lenovo key to turn on G570;

2. Press down arrow key once;

3. Press left arrow key 3 times;

 

Up this point, the G570 didn't  boot from my system repair  disk in the DVD drive which was created with Window 7 oOS.

 

So, I add another step after 1,2,3:

4. Press Enter key.

 

No response from G570.

 

Did I miss anything?

 

I also try to use F2 key to enter BIOS menu. But I didn't know if the BioS menu was entered. After F2 key, when I press downarrow or left arrow key, I only hear beep.

 

Thanks again for your reply.

 

Yiping

Hi Yiping , 

 

You may need to try it again using the BIOS simulator. 

Usually when you manage to enter the BIOS , caps lock and numlock key can be turn on and off .

Connect the external monitor to have a baseline if it went to Windows or stayed on BIOS before proceeding .

 

Regards

HI ,

 

Thanks for the reply. Sorry that I cann't fully understand what you said, such as cap lock and num lock keys as well as the external monitor connection. Since I can not see anything on the external display, could you explain step by step in terms of key stroke so to make the DVD drive as the first boot device?

 

Regards,

 

Yiping

Hi Yiping , 

 

I is realy hard to blindly map the step as it would be better of doing it along side with the BIOS simulator.

 

Start with shutting down the pc . Use the Novo button to turn on . 

This image of the Novo Menu would appear so press down once to choose BIOS Set up. Press Enter.

Now on a different pc map the steps side by side with the BIOS simulator .

 

It is a challenge , hope you can do it from your end. 

 

Regards

if you have another PC at home then you can install The OS to your HDD by connecting it as external with the help of some apps
