Help please lenovo z40 70

[aldopc]

Hello friends, I have this Lenovo Z40 70 without display, I found a bios here and it works but it does not recognize wireless cards, it only recognizes bluetooth, but I have already fitted several cards and do not recognize any, can it be a problem with the bios or can it be damaged before? Attached original file without display and file that boots and found on this site.

Re: Help please lenovo z40 70

you posted two bios of different lengths, remove the bios chip from the motherboard before writing or reading. I posted two bios, one extras from the Lenovo website and another Clean Me to your original. I hope it helps.

The bios has a "Whitelist" ,it will only use certain lenovo wireless cards,you can`t use any card you want unless the bios is modified.See this thread on bios-mods -

If it happened in older models, but in this case when starting the computer it is not sending a message from an unsupported wireless card ... enter the operating system without error warnings, I will try the Plague files and comment thanks for your help Smdflea.

Hello probe the two files both start but the problem only appears the bluetooth in the device manager, install a new operating system, but the wifi card still does not work, this card is the original from the team and I have tried it on another laptop and It works correctly, I saw the option that indicates Smdflea but I am not very expert to edit the bios and delete the whitelist .... can someone do it for me please

If friend I installed the power manager but the problem continues, I also tried the fire1234 file without whitelist, I was wrong to specify the model of the equipment is a G40-70 but the files you used are all from g40-70 I have doubts with the first dump since it is 16mb the original dump, all the others you tried are 8mb and none of them recognize the serial number or the name of the product, do you think that is the problem?

Bios to G40-70, white list disabled, serial numbers and windows key copied. The bios should have 8mb, I have never met in this model that the bios had 16mb.

Ok, friend, thank you very much, I appreciate your help, I have tried your file, but the wifi problem persists now if the serial numbers and the product name appear, but apparently it is a problem on the motherboard, regarding the biography of 16mb I already found what is the problem, I did a reading in the programmer software without selecting the correct chip, and I take a chip of different size and that's why a 16mb file was created you are correct this bios is 8mbn chip, Again, thank you very much.
