I have Acer V3-771G laptop with InsydeH20 rev. 3.7 bios, version 2.28 and all the settings unlocked. I disabled ”Internal graphics device” because I thought it would disable integrated graphics and then I could have used dedicated gpu only. But now my laptop’s monitor won’t turn on at all. I cannot even use external displays via vga or hdmi. I tried resetting bios by opening my laptop and taking bios battery out. I did that twice. Didn’t help. Now my only(?) option is to do emergency flash procedure which would go like this according my laptop’s service manual:

1. Format the USB storage disk using the Fast Format option.
2. Save ROM file (file name: VAG70X64.fd) to the root directory of USB storage. Make sure
that there is no other BIOS file saved in the same directory.
3. Plug USB storage into USB port.
4. Press <Fn+ESC> button then plug in AC power.
5. The Power button flashes once.
6. Press Power button to initiate system CRISIS mode.
7. When CRISIS is complete, the system auto restarts with a workable BIOS.
8. Update the latest version BIOS for this machine by regular BIOS flashing process.

Now the problem is that when I plug AC adapter in (step 4), my laptop powers on immediately, without pressing any button. So step 5 never happens. Is there another way to do this? Or a way to plug AC in so that it does not power on my pc automatically?

My first thought how to fix this issue was to enter bios blindly and press F9 which would restore default settings and then press F10 to save and exit. The problem is that nothing happened. I think that nothing happens behind the screen. I have set Skype to login automatically when I sign to Windows (my Windows account is the only account and no pw so it goes straight to desktop). I asked someone else to look if my account signs in Skype but it never did even if I waited long time...

The simplest way to fix it is to load the default values in the bios. You need to memorize the steps and the keys in order to enter your bios and load the default settings. If you forget the keys, check your user manual online.


Steps:
0. Turn off the laptop.
1. Turn on the laptop.
2. Press "F1" or whatever it is stated in your user manual to enter your bios.
3. Press "F9" or whatever it is stated in your user manual to load the bios default settings.
4. Press "F10" and then "Enter" or whatever it is stated in your user manual to save and exit your bios.

Note: If you set a password in the bios, you need to enter your bios password between step 2 and 3 as well.

Hope it helps!

Thanks for your reply but I already tried that. I know the steps how to do that in theory but in practice it just doesn't work, settings don't get resetted. I suspect that things are jammed behind the screen. I also haven't set bios pw.

You can reset the settings very simply. If you temporarily remove all your RAM sticks, and instead of them temporarily insert one another RAM stick (with different RAM size, or from different manufacturer).

Hello

I broken my bios very bad... I was trying to upgrade bios from 1.01 to 2.28 with the DOS method. Since by default it doesn't allow you to do that, i changed some parameters (/all and another one to skip the offset check) It flashed till the end with no errors but after restart i get the black screen.
Then i tried to do the Fn+Esc for the Crisis Boot but my power led won't blink like in the normal situations described. 

Can anyone please advise me why they crisis boot isn't working? What can i try more now?
