Lenovo Y410p / Y510p - unlocked BIOS / wlan whitelist mod / vbios mod

Recommended Posts

Hello everyone :)

Forgive me for the noob question as I am new here. I recently got a GT750M for my y510p ultrabay. The official BIOS flash from Lenovo doesn't work and I refuse to go back to Windows 8. Does this mod allow me to have SLI on Windows 7? Thank you

vBIOS update not required for SLI in Windows 7.

But I still need to flash the ultrabay, right? My laptop isn't recognizing the second GPU and Lenovo doesn't provide support for windows 7

No you do not. If you want to overclock and overvolt you can still flash it, but not mandatory for functioning SLI in Windows 7 unlike Windows 8. If Windows doesn't recognize GPU it is a different issue. Maybe check that card shows up in Device Manager and SLI is enabled in Nvidia Control Panel.

Lenovo provides official Windows 7 drivers on its site but ofc downloading latest versions from manufacturers' websites is recommended.

unfortunately, there is no second nvidia driver provided by lenovo for windows 7, i already try install second video driver for windows 8 & 8.1 at windows 7, but not work, nvidia wont detect the 2nd GPU.

Hello, guys. I have a y510p and intend to try this bios mod. One question tho - does the vbios for the second 750M give a performance increase by itself or do i have to work the clocks from the bios?

Could anyone kindly please make a list of the BIOS settings which do not work, or which brick/fry the notebook? I've read through a few pages and seen that volting and clocking may do this to the notebook, but does shutting a couple of cores off do the same? Also, is that option even there? And, finally, does the BIOS have the option to switch to the IGPU whilst both the discrete cards are inserted? Just want to get all my lists checked and see if the modded BIOS would actually help me do any further power saving or not. :(

Hey guy, I think, I've found option in bios that stop cpu from throttling when gpu temp reach 65 degrees. It's ACPI 5.0 CPPC Support and ACPI 5.0 CPPC Platform SCI in Advanced CPU Control under Power tab in Modded Bios. I heard it was cpu powersaving feature in Haswell so I enabled them and install this driver (Intel Collaborative Processor Performance Control (CPPC) Driver for Windows 8.1 (64-bit), 8 (64-bit) - ThinkPad - Lenovo Support (US)).

Then today I ran Heaven Benchmark and gpu temp had gone high(75 degrees and 85 degrees) but to my surprise I monitor my cpu using XTU and saw that cpu still turbo boosting and doesn't throttle.

About the CPU performance: When driver was installed there is new option in windows power option called Intel CPPC Energy Efficiency Settings. You can enable or disable it (Default are "Enabled" on battery and "Disabled" when plugged in). I leave it at default setting.

I apologize if this is a stupid question, but I am new to these mods. If I flash my BIOS in order to install an intel 7260, will this affect me in any way other than the warranty?

I am going to flash modified bios to test it out. So now we can disable throttling semi-official way :D.

Hi, I've buy a Y510p with a single GT750M GPU, and I've brought a GT 750M5. But I'm getting the message "unauthorized slave vga card is plugged in. power off and remove it". Will this version fix my issue? Best Regards

Whats the version of original unmodified version of your bios? If you have old bios try to download official bios update from Lenovo and also download vga bios update from this thread. Its second post. Make sure you pick 750m bios. Just follow the instructions.

If it will fix your issue I dont know but you can try. Where did you bought your laptop and second vga card?

Thats the official fix from lenovo as I said before, you have to have updated bios and also vga bios. You can download original bios from the link above.

If non above worked try modified bios. And if it still dont work then speak to Lenovo technical support and ask them for help.

I brought this computer at Ebay. Work wonderful with a single GT 750M, but I've brought another GT750M5 separately, computer has Bios 3.05 but it display that message when I replace the original optical drive with the gpu. I have contacted Lenovo support but they don't want to help me as my warranty expired 2 months ago. Computer won't boot with the second gpu, so the problem is not that videocard is not recognized by windows, the problem is that the computer stops booting and display this message.

Sorry, but I can't seem to get Step 1 to work. The backup.bat file run in Admin Cmd prompt doesn't spit out a bios back up anywhere that I can see. Is there an alternative to this step?

OK I managed to get to the dragging and dropping a backup bios into the biosfixer, but ended up with this:

"Input file: bios.bin

ERROR - invalid input file. Make sure it's a proper dump of BIOS version v1.07, v1.09 or v1.10"

I didn't run anything with admin prompt or admin priveleges because when I did, nothing happened. No backup bios was created and the biosfixer with admin priveleges wouldn't let me drag any files onto it.

Did you tried modified bios aswell? Well you have bought non-sli version then probably. They should at least tell you if its going to work or not. Cheeky bastards those lenovo technicians.

If modified bios is not going to work then you might be out of luck. I bought 755M SLI version . I was in temtation to buy it separately but I was lucky that I spotted great deal on this model in my country so I bought it cheaper than lenovo sells it. It was however DOS version but I can install clean windows myself without any crappy preinstalled software as manufacturers do them.

If you really have non-sli version then you are out of luck as non-sli versions are probably not able to deliver enough power for second ultrabay vga. Even if you have got 170W power adapter. Sorry but you better sell that laptop and that card for whatever you can and buy SLI version with ultrabay card.

Nevermind I figured it out. Bios modded successfully, but just discovered that the Intel 7260 wireless-n chip I ordered is a DoA... effing Murphy's law.

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
       
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!
