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!

      Hello, 
      I own a Lenovo Y510p with a GT755M SLI configuration (which almost always overheats/crashes for games that DO support them) and i plan to set up an eGPU for it.
      I've done a considerable amount of research on the topic but there are still doubts to ascertain before moving on.
       
      1) Is it possible for the latest series of GPUs (GTX 1070, GTX 1080) from Nvidia to be used as an eGPU? Those who've already tried it used stuff like the Razer Core or it's other branded equivalent. What I'm looking for is the complete DIY version using the EXP GDC V8 connected to the mPCIE underneath the laptop (the one which the wifi card uses). I am aware of the Thunderbolt tests on Macs but I'm curious about it's performance on the mPCIE. And would it be compatible with the mPCIE adapter? Would it be too "new" for my laptop bought in 2014? 
       
      2) If it is possible, would it be worth it? Would the bottle-necking of the mPCIE be enough to diminish its worth? I wouldn't want to go for the GTX 970 or GTX 980 because my long term plan would be to use the GTX 1070 on a desktop set up once I settle down. (I'm a travelling student btw)
       
      Thanks in advance.

      Hello!
       
      I have a Lenovo Y50 with a shitty Wifi-Card and i wanted to unlock the BIOS, so i can replace it with a better one! Now I saw there are Instructions for the Y500 but none for the Y50! Is there a possibility for me to unlock it on my own, or do I have to rely on other Users on this Forum, who know how to do it? Greatly appriciate any help regarding that matter :/. My BIOS is on V1.13 by the way.

      After months of figuring out why my Alienware M14 R1 has been overheating, I've discovered that it had something to do with the bios.
       I've tried every compatible BIOS on the Dell website and have failed to solve the problem. Still gets hot even on idle.
       Except, Dell doesn't have A06 for some reason.
       
       Do you guys have a copy of the A06 BIOS? Dell Customer Support is pretty crappy .

      Hi together :-)
       
      As the title says I'm having a little Issue after upgrading my m6700's graphics card from the K3000M to the newer K4100M:
       
      Everything seems to work properly, but under load (i.e. 3D applications) it produces crashes / system instability after ~5-20 seconds.
      When I reduce the chip- and memory-clocks in MSI Afterburner as far as possible, it takes a bit longer until it crashes, but eventually it always does after a minute or so.
      When running on battery power (and thus even further reduced clocks) everything runs stable for arbitrarily long times.
       
      This sounds like a thermal problem to me. However, the reported GPU temperature never exceeded 65°C, which I think is OK.
      I guess the memory chips are not temperature monitored seperately, are they? So maybe I should replace the memory thermal pads by new ones?
       
      What I've already tried/checked/looked at:
      - Uninstalled previous drivers with "Display Driver Uninstaller"
      - Latest Nvidia Drivers can be installed properly (and also tried a few older versions)
      - Notebook BIOS is up to date
      - Tried three different Video-BIOS versions
      - Graphics card is not recognized by Notebook BIOS properly ("Unknown video card")
      - Graphics card is recognized under Windows, though (Device-manager / Nvidia control-panel / GPU-Z and so on)
      - Sometimes after a crash the system recovers and a pop-up says that the nvidia graphics driver crashed and was restarted
      - Of course, I'm using the large 240 Watt Power supply
       
      Ok, that's about everything I remember to be relevant at the moment.
      I'd appreciate any kind of help :-) ... If you need further Information, just let me know, and I'll try to deliver it.
       
      Thank you, Florian
