Hey guys!

 

Earlier this week I upgrade my laptop with a new network card. I bought a Intel WiFi AC 7260 for my Lenovo Y510p.

So most of you probably know, Lenovo's BIOS has a whitelist. So I flashed the BIOS so that I could use the new network card. This happened without any problems, I installed the network card and booted my laptop. Drivers worked the moment I logged in and connecting to a network was easy and fast. Checked speedtest.net for the up and down speeds, perfect!

 

There is a problem I encounterd though, it has nothing to do with my BIOS (I think) or my new network card. It has something to do with my GPU's.

I run an SLI configuration of 2 x Nvidia GeForce GT755m. (one main, one ultrabay)

 

I was following a guide made by @svl7 about flashing the BIOS. After the part of flashing the BIOS there was something about flashing the vBIOS too, because if you are running 2 GPU's it was not going to work properly. When flashing the vBIOS I encountered the problem.

 

As explained by the guide, I used NVflash to flash vBIOS, when using the command "nvflash -a" to view adapters and their "index" they were on "0" and "1". I tried to flash both of them, "1" flashed easily without any problems, "0" did not flash at all.

Now the error displayed was: "ERROR: GPU NOT DETECTED."

 

Has anyone got an idea of how to fix this? I'm not able to flash one of the GPU's. If I play a videogame on my laptop, every now and then (intervals of 1-5 minutes) my screen goes black, audio stutters and comes back to normal after a few seconds.

 

Hope you guys can help me out! If there's any info you need let me know and I'll edit the post!

In your laptop one vbios (for 0 graphic card) is a part of main system bios, and can't be flashed by Nvflash program. Vbios for 0 graphic card automatically will flashing when you flash mod bios from svl7.

Another vbios (for 1 graphic card) can be flashed by Nvflash program, and you already do it.

Now, if you have problem, just flash again main system bios from svl7, and then flash again card 1 with Nvflash.

@Klem Sorry, I wasn't able to use my computer until today, I updated to stock Lenovo BIOS but I didn't have my old wifi adapter with me so I couldn't turn on my laptop anymore lolToday I swapped the wifi adapters and tried to flash BIOS again, I have no more problems with my SLI GPU's!

  1. Solution (That worked for me):
  2. I kept the 2nd GPU flashed with the custom vBIOS, I DID NOT!!! flash to stock vBIOS!
  3. Installed the update to stock Lenovo BIOS v. 3.05
  4. Downgraded to BIOS V 2.07
  5. Prayed to the BIOS GODS!
  6. Flashed BIOS to custom BIOS V. 3.05 by @svl7
  7. PROBLEM SOLVED!

@Klem thanks for helping me out!

In my laptop I have 2 GPU's, one main and one is in an "ultrabay" which you can remove/add really easy. This one I flashed using a program called "nvflash".

The other one, as explained by Klem above, can't be flashed seperately. This one is flashed together with the main BIOS.

 

So I think, yours can not be flashed seperately but is included in your main BIOS.

      Hi everyone, I have a problem. I need to unlock the bios settings because I only have basic functions and I need to increase the memory of VRam. Sorry if I posted a post not in this topic.

      In this thread you can post your requests for Lenovo ThinkPad X240.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden advanced menus and settings in bios setup menu, or upgrade to new display (with brightness control), then you can post your request in this thread.
      Important!
      For creating your personal bios dump and to flash your bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      I have spent a little time in the past few days looking around this site. I would love for someone to point me in the right direction to a forum that has information that could help me out with my problem.
       
      I have a:
       
      Alienware M17XR3 
      Windows 7 Home Premium 64-bit
      Intel I7-2820QM 2.3
      Bios InsydeH20 Version 1.0 A12
      NVIDIA GeForce GTX 460M
      (4x) 4 GB Ram
      samsung 2.5" 256 SSD (SATA3.0Gbps)
       
      It has been an amazing machine for the last 10+ years. Minor issues, nothing that an Alien Respawn could not fix, till now! On battery power it works just perfect.  Then I plug it in and it's all OK until I try to do anything, and then the screen goes white. The screen sometimes goes yellow, sometimes blue, but mostly white screen. It will do nothing until I do a hard reset (holding the power button till it turns off and turn it back on) with the power unplugged.  If the power is not unplugged then it will go through boot up to windows swirling dots then go white again. If I plug it in and do nothing I can charge it, unplug and continue what i was doing. I have tried a lot of solutions bouncing around the internet, and thought I was having a DC Jack connection issue (replaced the ac/dc power adapter, then the motherboard). I get a better connection now but with the same white screen result. I stumbled into this forum and I'm hoping to find solutions to my issues.  Then upgrade like so many others have.
       
      Any ideas, comments or suggestions welcome.
       
      Thank you in advance!

      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
