Bricked Bios Acer Aspire 7720 ICK70

Hello friends!

About three or so months ago I bought an old secondhand Acer Aspire 7720 with a faulty MXM II Nvidia Geforce 8400 GS Vga card which halts the laptop when it was forced to work harder, so I bought a new MXM II Nvidia Geforce 9300 GS Vga card. I inserted it inside the computer last friday night and the laptop started to work again.

Then I thought it would be a great idea to upgrade the bios with a suitable new one, with all the whole menus, from this web https://www.bios-mods.com. Then, the first time, the laptop started and I could get in the bios menu, and loaded default values, saved it and then the computer screen got black.

Aparently the computer starts OK but the screen remains black. I have spent several days searching for how to fix it, and in this forum I have found how to do it, I have done it like in severals threads say, like in this one.

The laptop gets in the recovery mode, following all the steps, connected to the AC power with no battery, pressing Fn+Esc keys as well as the power button, and releasing after, inserting a CD-RW with only an ICL50HW.FD file, and the DVD drives reads it once, twice, and even three times but never powers off, so I finally switch it off.

I've tested with different bios versions 1.45 and 1.11, but never works.

I do not know if it is important, but yerterday I realized in the bottom part of the laptop it is written it is the ICK70 model. Maybe I have to change the bios file name and it will work.

Thank you in advance, I hope you can give me a good solution.

 

I was waiting an answer and nobody gave it to me.

Finally I found it in another forum. The problem was that the laptop didn't read correctly the bios file.

In the forum I found an ISO image of a DVD with a bios fd file and finally it read it and worked. Then later I upgraded the bios version and now it works fine.

Thanks anyway.

I left here the link to the forum thread with the ISO file with the BIOS version 1.19 inside.

 

So, as I thought, name of the BIOS image has to be specific? Not just a set of letters, yes?

In addition, in case of laptop unable to read the BIOS image during emergency restoration of the BIOS with WinCris it is always good to try different versions of WinCris. When I bricked my BIOS I`ve tried different versions of WinCris and only one of them worked. The name of my BIOS image was BIOS.WPH.

 

I think the name of the bios fd file depends on the bios to unbrick. In the case of ICL50 and ICK70 motherboards which work with an Insyde Bios the name to unbrick them is ICL50HW.FD. But I am not speaking from a proved knowledge but also after a bitter experience.
