Bios Mod And Password Reset - Insyde Lenovo G560

[eknsi]

I need help with a bios mod and resetting the bios password. Can anyone help me?

I didnt forget the password, My Ex girlfriend put a new password and now i cant get a hold of her, changed her number and everything.

By the way i can log into windows just not change setting or go to bios.

Well, i think you should take her by the hair and make her tell you the password. Me personally don't support password removing in other equipment that is not mine.

Anyway i should try the obvious methods like removing cmos battery.

Well I've heard from a lenovo repair guy that if you remove cmos battery you can mess up motherboard, I have the nano bios programmer I just don't want to have to void my warranty, just looking for a simple backdoor.

I know this may be the wrong section to ask, but I need help from someone who knows insydeh20 bios'es, and lenovo systems....

I have a lenovo locked with a supervisor password... I have confirmed that removing both system battery and cmos battery do not clear the password, and it provides no hash code/hint, and can find no jumper to clear cmos type settings!!!.
I have also extracted the said platforms latest bios update http://download.lenovo.com/UserFiles/Dri...ivers/G460&G560/BIOS/29CN38WW(V2.15)/NIWEx215_X64.exe and modified the platform.ini to clear the password upon flash... again no success...
I have the laptop schematics, an arduino, bus pirate, and the general know how to read/write eprom and flash chips, however i have been told on several occasions that the PW is stored on a *different* rom chip in the system.
So I am looking to answer the following:
1. would the PW be stored on the 4MBit flash chip(ie the bios flash) or a different chip(if this is the case, where?, I found the 4mbit rom, and a EC rom on the schematics http://hpwlabup.com/lenovo/hpwlab-lenovo15878e596c.pdf [that appears to be related to user io, like kb and touchpad])
2. how would i go about extracting(ideal), or resetting(acceptable) this password (maybe not an exact guide, but at least an idea...)
AND YES I READ DOGBERTS PAGE... hehe lol, I wish it was that easy...
