[REQUEST] Lenovo G500 (78CNxxWW) BIOS Unlock

[Dudu2002]

Hi everyone, not sure if I am in the right place so I'll ask first to not waste anyones time: I bought myself some cheap 3rd party battery packs for my Lenovo G500 and the current BIOS version has a serial number lock and tells me those are bad and won't use them.

The vendor told me to downgrade to an older BIOS version which I can't get my hands on though so I am stuck.

Is there a BIOS/procedure available to make my knockoff battery packs work in the machine?

Hi
the control of the battery is carried out by the EU
if you have previous versions of bios, you can experiment...but I doubt that this will help you
P.S. In my opinion, the right choice is to turn the battery back to the seller

And where would be the fun in that? :-)

I guess I will try to adapt this piece here to my situation: http://zmatt.net/unlocking-my-lenovo-laptop-part-1/

That beeing said, I would kindly request modification of my BIIOS (ROM File can be found here http://www.rapidshare.com.cn/3AMULvr ) - whatever is possible. WLAN replacement and more BIOS options to play around with sound great to me!

Hello, can anyone please unlock my BIOS in my notebook, Lenovo G500?
Also if there is some whitelist and it is possible to remove it and safe, then can it be removed as well, please?

I am using Windows 10 64-Bit.
Though, this notebook is specifed for Windows 8.1.

I want to take look on Intel SpeedStep, maybe later External GPU.

I think I never did some BIOS modifications installation or something like that, so can I get some simple instructions please or some link to the instructions?

When I launch this setup it says I have the same one:

Hi,
I want to remove white list in order to change wifi adapter to another. I tried to replace wlan id in original bios, but have troubles with flashing moded bios: InsydeFlash performs security checks and does not flash modified bios + crisis recovery procedure does not work as well.

Could somebody just remove white list checks and give instructions how to flash new bios?
