I have a Lenovo Y580 with 5DCN90WW (V8.01) BIOS and I want to remove the WL.

I want to make a copy using fdpw64 but I got an error:

"Error 104: The 2 SPI Flash devices do not have compatible command set."

The 'Error 104' - fix I have another error:

"Error 103: There are no supported SPI flash devices installed."

I remember seeing this mentioned in earlier posts. Search the thread, you should find the solution.

Hi!

I brick my Y580 when tried flash unlocked BIOS 8.01 over 8.00. I was trying to restore BIOS all weekend, but have no rezults. My PC started, switch on fan and switch off. But yesterday I plugged vattery, inserted flash drive with unlocked 8.00 into USB 2.0 port and pushed different "Fn+..." and "Win+.." combination, and my laptop switched on and started restore BIOS. Unfortunaly it`s not help.

I tied to reflash my backup, but I get same situation: PC started, switch on fan and switch off.

Maybe I pushed some kinde of "key combo" reseted CMOS... Does anybody have any idea what can happened?

Does anybody know where the cmos battery is located exactly? I flashed the 8.01 modded bios a few months back and haven't had any trouble. But I went into standby yesterday and now I cannot get it to boot back up, no POST or anything.

*EDIT*

I found the cmos battery after opening up all the components, shorted it and made no difference. I have been trying the insyde recovery methods but it does not seem to accept the files I throw at it, like QIWY3.bin.

Does anybody have any experience with the bios not POSTing? My y580 turns on then turns itself off after a couple seconds, but sometimes it stays on, I'm really clueless.

I can verify that the v2.0x mod works with my wife's Y580, I have yet to try the v8.01 on my own Y580 though.

8.01 was working on mine for a few months now but a week or so back my laptop stopped POSTing. I had stock 8.01 before flashing the modded one. Still trying to figure out the recovery method though to restore to the original bios.

I have problem with my Y580, I was accidentaly installed G580 bios for Y580. Now flashed with right original Y580 bios 5DCN90WW (V8.01), but EC version still remains for G580 5ECN96WW. Due to this fact some functions doesn't work: keyboard backlight and some functional buttons. Already tried to flash with modded bios version from first page, but EC version still remains. I think, that EC change is not included in BIOS file. Could you help me how can I get back EC version to factory?

I have attached original Y580 BIOS file 5DCN90WW (V8.01) - it's factory backup from laptop with right EC version.

Try restoring it via BIOS recovery. Search this thread for "bios recovery" and select my username in adv search, I posted a tut some pages back.

Never gave a second thought to my wireless card in the y580 (always hardwired) until I moved recently and started using wireless. I wasn't aware that such an awful card accompanied this laptop. All my devices were receiving the 5ghz signal from my Asus router except for the most expensive, seemingly most advanced of all: the Y580. Also ran into problems with the 2200's compatibility with certain Linux OS's.

So I decide to buy a new card and find that there's a whitelist? This type of proprietary garbage should be unlawful. If I wanted to buy specific/limited hardware, I would have bought a Mac.

Now on to the unnecessary time waste of modding my BIOS. Next time I think I'll skip over Lenovo when dropping $1300 on a laptop.

Hi everybody , i just bought a lenovo y580 , with fresh install w8 and the las graphics drivers , i obtein in 3dmark06 only 13548 . If i repeat the benchmark ,this decrease to 12800...

the temp in graphics is always less than 71ºc . Is it OK? i monitored it with msi afterburner. I´m thinking upgrade to an unlocked bios because i dont have thermal issues.

Anyone have the issue of decreasing performance?

I do some test changuing energy setting (lenovo performance), and now i obtein 93ºc while i play at BT4 betwen 35 and 45 FPS, with medium setting at 1920x1080. Turbo is always working ( 935Mhz ) and processor at 100% in energy setting. If i changue the energy settings to Balanced, the temperature decrease to 83-84ºc ...

I have a question, If i changue to unlocked bios , with 1Ghz fix in core of graphics car ,could i have overheating? (more than 93ºc when i play)

Thanks everybody.

If you are already seeing 93C you most likely will see higher temps with 1Ghz, and potentially see your computer shut off to protect the GPU.

What you should do, even if you don't install the modded BIOS, is to repaste your laptop. I saw 93C (with artifacts) before I repasted and had temps drop roughly 20C afterwards using Tuniq TX-4, depending on the game. The highest I have seen it go at 1Ghz is around 78C.

If you expect your temps to drop 20C based on others' results, you will probably be disappointed. There may be others, as well as myself, who saw drops like what I did, but there are so many variables in repasting that you may see less than what I and others saw. Do your own research into the thermal paste that is right for you and "proper" methods to reapply the paste you choose. Don't go by what others have said/done. Evaluate whether or not you want to install the modded BIOS on the results you see afterwards and if you will benefit in doing so.

Although this is a rather constructive forum and pretty much lacks any ill-will, this is still the Internet.

I have been trying for over a month to recover my 8.00 bios to no avail, I still randomly try different file names if I have the will to do it.

Hi there. I've been thinking about flashing your BIOS, but I have one doubt. Is the BIOS version kinda related to a OS ? Do I need a special BIOS version depending what OS version laptop i got ? I see there are two basic versions: 2.0x and 8.0x I don't want to brick my laptop so I need to be sure. I've got 2.07 BIOS (from Lenovo website) and originally my Y580 was without an OS. Now I am on Windows 8.1, So what BIOS version should i flash ? 'Lenovo Y580 / Y480 BIOS v2.07 (5DCN40WW) -> unlocked, whitelist removed, Nvidia 660m @ 1GHz default 3d clocks,' this one ?

      Hello to all big format laptop users!
      I`ll try to make it as short as possible. I have the Alienware M18X R1 for about 7years, i think. It was a problematic machine all the time. But during warranty period local support fixed everything super fast and free of charge :). I even upgraded from gtx 580m sli to gtc 780m sli. And made primary hdd samsung evo ssd. Unlocked Bios. Power brick i changed 3 times by now. Battery once. And 6moths ago one of the long time ago installed 780m died ( started with artifacts on screen then refused to boot windows). Replaced that and was as happy as ever. The machine kept working stable and i pushed all i could get from it in reasonably modern titles. Even tried RDR2 on default settings, gave me 17fps :). Not sure if SLI is supported for that game. The point is it was running fine for last 6 months.
      What happened:  Gaming as usual, room temp 23C. After around 2hr suddenly black screen. The laptop switched off by itself.
      What i check: First checked power brick. Green light off. Unplug from wall and laptop. After plugging in wall green light back on. Connect laptop light off.
      Next: Tried take out battery, unplug. And hold the PWR button for 1 min. Try to start on battery - nothing. Plug in - green light off again.
      Later: after some googling found that need to try to remove video cards. Done that. OK Nice! Plug in power and it starts as nothing happened on the integrated intel video.
      Found out that i one of the video cards is plugged in that triggers the power brick to trip. (the original upgrade 780m from years ago). 
      Start with GPU: Insert the other one in its slot. Systems start. But immediately i notice there`s no video drivers. OK i think reinstalling and job done. Drivers reinstalled, asked for restart. After restart nothing. Still no driver.
      Windows device manager: This is bogging me. it shows that i have 670M instead of 780m. Windows gives Code 43 Error.
      BIOS: I go into bios just to find that that it has reverted back to A05 (hows that possible?). And its so limited that i cant even choose witch video card to use. But it detects nVidia GFX.
      How to get at least my single 780M to be working?! Update bios again to unlocked? Did this event fry Vbios on my other card maybe?
      System: m18x R1
      SLI gtx 780m
      Unlocked bios (before event)
      nvidia driver 443.x(or there about)
      Win: 7, 64bit

      Hello there!
      I am new on the forum. I'd need some help. I own a lenovo ideacentre t540-icb g, and i would need to unlock all the options in my bios, especially overclocking and thermal configuration. I tried with both amibcp and mmtool, but i didn't succeed (Error 18).
      I wonder if you could help me or give me some advice.
      Thanks in advance.

      Hi,
       
      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.


      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!
