I don't know these laptops as I haven't had one and for me is only theory, but I think It will be possible reinstall Win8, but activation is on HD so formatting It You'll lose licensing !
To unlock Win8 password there are many examples, have You tried which ones I posted ?
I need to know for Bios what can You do when going into SetupUtility ?
Do some photos (screen shots to illustrate to me the issue please) !

Extract from Service Manual :

BIOS password problems
I forgot my password. • If you forget your user password, you must ask the
system administrator to reset your user password.
Sleep problems
• If you forget your HDD password, a Lenovo
authorized servicer cannot reset your password or
recover data from the hard disk. You must take your
computer to a Lenovo authorized servicer or a
marketing representative to have the hard disk drive
replaced. Proof of purchase is required, and a fee will
be charged for parts and service.
• If you forget your administrator password, a Lenovo
authorized servicer cannot reset your password. You
must take your computer to a Lenovo authorized
servicer or a marketing representative to have the
system board replaced. Proof of purchase is required,
and a fee will be charged for parts and service.

So I don't know if It's an user or Adminitrator Bios Password, but I know that lately
Bios is going to save that Password into Eeprom Bios Area, so only rewiting a Bios Backup without password can recover It.
So the scenario can be :

1. To buy an External USB SPI Programmer with a Pomona Soic Clip reprogram Bios
2. Format HD and try to install newly Win8

I don't know if rewriting Bios can unlock It, but We can try !
Let me know

I also have a G505s that I would like the advanced menu to be unlocked (3.00)
What is strange though is that I managed to access the power and advanced menu ONCE on this laptop by booting into uefi option on the recovery settings of windows...I was not aware of what buttons I was pressing as the laptop was posting and restarting

I would be very grateful is someone could please unlock the power and advanced tab
please let me know
Regards

ps: Here is the link to the bios file from lenovo: http://download.lenovo.com/consumer/mobi...(3.00).exe

Dear Community,
i read alot about Mod-BIOS for my Lenovo G505s,
but no solution was found.
I am neither an expert nor an idiot, i did alot setting up etc. and i wanted to know if you guys can help me out.
Currently, my Laptop is running on BIOS v.3.0 and it can be downloaded here:
http://support.lenovo.com/us/en/products...s-notebook
i'd be very thankful, if anyone here is able to create an unlocked BIOS for that thing, because actually you can't change ANYTHING, no RAM-Speed, no voltages, no frequencies, simply nothing at all...

Dear friends, did you know that there is a Coreboot Open-Source BIOS project?
You are lucky - Coreboot supports your Lenovo G505S laptop!  This is a truly unlocked BIOS:
no limitations, no Wi-Fi whitelist, and because its open source you can modify its code as much as you want!

Who needs InsydeH20 proprietary crap, when you could have Coreboot open source master race?

http://www.coreboot.org/Board:lenovo/g505s - description page, although slightly outdated
http://www.coreboot.org/Download_coreboot - download page
http://www.coreboot.org/Build_HOWTO - build instructions

Note: I didn't know how to flash a produced 4MB BIOS image to SOIC-8 BIOS chip,
so I got a cheap USB SPI flasher + SOIC-8 test clip from China, costed less than $20...

Compilation: Just follow the instructions from Coreboot wiki at the links above
It seems that a Coreboot for this laptop is not a Libreboot yet, it still needs a closed source VGABIOS which weights 64KB and should be extracted from a stock BIOS:
http://www.coreboot.org/VGA_support - use this instruction for doing it; although it recommends extracting from vendor BIOS I've done it through "Retrieval via Linux kernel" way.
Everything in software world that is closed source, could potentially have the backdoors demanded by evil gov three-letter-agency which could be a very serious security risk...
However, you could enable YABEL option in coreboot's menuconfig to prevent the possible undocumented accesses of VGABIOS to other PCI devices of your laptop

Flashing:
I disconnected all the power sources: charger and battery, then teardown Lenovo G505S (it was really easy after watching photo/video instructions at the Internet)
Located a SOIC-8 BIOS chip on the laptop's motherboard, it looks square with 8 legs and a dot in corner marking first leg - for a correct SOIC-8 test clip installation.
In my case, BIOS chip had a cFeon label - not MXIC as specified on description page above - and it was located at the bottom closer side of the motherboard.
Carefully put SOIC-8 test clip on this chip, which was connected to USB SPI flasher which was inserted into other laptop, then I made a backup of proprietary crap BIOS
(just in case of failure). Flashed Coreboot 4MB image to this BIOS chip, then I disconnected SOIC-8 clip and assembled this laptop in reverse order of teardown...

Result: after installing Coreboot BIOS everything works perfectly, much more freedom, and boots so much faster than before!

P.S. Because this removes a whitelist, I think its appropriate to give here a good WiFi card advice:
Atheros AR9462 or Atheros AR9485 . These Atheros cards work very good, cost cheap, very stable WiFi,
and they work perfectly under Linux without needing any proprietary firmware drivers
