That right... there are menus that you should be careful with settings.

I will try to make more pics.. sometime today.

Great news :frog:

Thank you very much !

Do you think it will be possible to have a bios version that will remove the wifi-card whitelist system ?

I really need to install a dual band wifi card on my Y580 ...

There's a wifi-whitelist in the bios? I need to look into this, could be removed, possibly.

That's lame they put a whitelist..I was looking forward to replacing my 2200n with a 6235

I don't think this is a good idea : there is already a bluetooth 4.0 broadcom chipset which is integrated (as the 2200n doesn't have bluetooth 4 ...).

So if you install a 6235, you'll have two bluetooth devices : the intel and the broadcom ...

A 6205 seems to be a better option for me :encouragement:

Thanks for pointing that out. It makes better sense. Somehow I thought the Broadcom bluetooth chipset was integrated on the same package as the 2200n. Guess I should of read up more on how everything was integrated into the Y580 with the different devices and chipsets. On a separate note, has anyone been experiencing weird wifi issues with the 2200n and the Windows 8 enterprise trial version? I have the latest 15.5 intel drivers and sometimes when it comes out of hibernation, it won't allow it to connect to any wifi APs and shows a stale list of available APs without refreshing. Disable/enable the wifi seems to correct the issue. I'm thinking either driver related or some Windows 8 bug.

Do you really think that Lenovo could have created a special 2200N version with a broadcom chipset integrated ?

I'll try to remove the wifi card tomorrow just to be sure.

I don't have this problem on W8 RTM.

You are right. My bad. It's a separate module. It's a BCM920702 with a separate connector on the motherboard. I found the reference in the Y480/Y580 Hardware Maintenance Manual found here: http://consumerdl.lenovo.com.cn/UserFiles/UserGuide/en/User's%20guides%20and%20manuals/Y480Y580/Lenovo%20Y480&Y580%20Hardware%20Maintenance%20Manual%20V1.0.pdf

Ok, I checked this morning by removing the wireless card : the bluetooth is still working !

So the only remaining problem for me is the wifi-whitelist ...

If it could be removed, it would be awsome :orange:

How big of a problem should it be to install a wifi card that has bluetooth on it? Couldn't you just simply disable the Broadcom chip or the Bluetooth feature on the wifi card?

Another thing I noticed is that the Broadcom chip is connected via the USB bus. I find that kinda weird, shouldn't it be going through the PCI bus if it's soldered onto the motherboard? (at least, I'm assuming it's soldered on).

You don't need to remove the wireless card to see the bluetooh module to work..

just go to the stock bios and disable the wireless lan, that it..

Alright, got a version here which should allow other wlan / wwan cards as well. Have never looked into this before, but this should do the trick, else let me know.

It's a test, I need to know whether it works as intended or not, some people sometimes fail to see this point and just grab the file and I never hear anything back from them. That's why I set a password on the archive, if you want to test it let me know and I'll give you the pw, but I'll expect you to let me know whether it works or not. Sorry about this inconvenience, but I'm afraid it's needed.

Once confirmed to work I'll upload it to the frontpage, as the unlocked version without the whitelist tweak.

- confirmed to work, file moved to first post -

Yeah, will do. Are you already able to overclock using software like MSI afterburner?

I didn't add anything, I removed the check.

Regarding PXE - no idea, that seems to be in the stock bios, so it should definitely work. Maybe another Lenovo user can help you out.

svl7 - yea we can already overclock the GPU with afterburner :) a modded vbios would be awesome.. also just in case if anything goes wrong with this bios how can you recover the bios? say in the event of a corruption? I remember my old asus netbook you could put the bios on a USB drive and hold the power and esc keys and it would recover the bios from the USB drive. Any recovery methods for this laptop?

Recovery method should be similar to the way you mention, I don't know the key combo for this system, but all recent Insyde firmwares use this recovery.

Regarding the whitelist removal - @Martin de Regt told me that it works fine, no check anymore. Thanks for testing! :)

+ added to the first post.

Great.. I will be looking for a good dual band pcie wireless card now...

as for my LAN at boot problem I got resolved by loading the proper driver..

as for WOL from total shutdown still a puzzle ?????

if anyone with this mod bios willing to try the right bios set up: >> lan cable in then plug the ac cord

the lan light next to the cable should blink. that my goal... BIOS puzzle ... hummmm.

svl7-I tried to download the mod bios without the WLAN whitelist to try and was not allowed too. I'm wondering if you are still testing it and will you make it available to the rest of us? By the way great work in unlocking the bios!

      Which one of the above is the official website dedicated to Prema BIOS mod and why they all seem dead? Including the last one - according to TechInferno, Prema's last visit here was on Dec 2, 2016. Is Prema long done with creating custom firmware?

      Hello!
       
      I think I have a Clevo W942SW rebranded as a Positivo Master N250i in Brazil. I'm pretty sure it's a Clevo W942SW because even some Clevo manuals about this model carries the "POSITIVO" brand in pictures. And everything else matches perfectly, as I could perceive.
       
      Well, it has a "Aptio 4" BIOS from what I could see, and the stock BIOS is pretty damn locked up 
       
      Here's what it looks like from the AFUWIN program:
      https://imgur.com/a/Vd71t
       
      And here's the BIOS dump, I think:
      https://www.sendspace.com/file/zp0ywq
       
      Any information would be very nice about if it's possible to unlock/mod this or not.
      Thanks!

      Hello everyone!
       
      I have been going all over internet (well ok, let's not exaggerate) trying to find how to unlock the bios on an old Lenovo G500 with an i5-3230M processor.
      I did try to check if there is any updated bios but that's not the case.
      I also tried using Intel's Extreme Tuning Utility but it looks like I am locked out of any changes.
      I would love to disable Intel boost (3.2 Mhz) and set my actual frequency beyond 2.6Mhz where it stands now and raise it to (say) 2.9 Mhz and see if the stress tests allow for that (temperature-wise).
      Also, I would like to try some gradual undervoltage (if any of you have managed something in this regard, I would love it if you could share the details).
       
      Beyond that, I have a crappy Intel HD Graphics 4000 GPU and I am almost certain I cannot get anythin more from it, but still would love any tips (if any, which I doubt tbh).
       
      Finally, I have added two 4 Gb Gskillz DDR3 and I was wondering if there is any point of changing their clock frequencies.
       
      By the way, this is my first post here, so I am eagerly awaiting to see what this community is all about!
       
      Cheers,
      Konos Vita
