Hi, all! I was able to successfully flash my bios some time ago; I noticed that the integrated Intel graphics controller now shows up in the bios, and in Linux; however, trying to activate it doesn't work because while it's there Linux (PopOS!) can't seem to set the backlight level on acpi:video0. I'm thinking there's a mismatch in the eDP/LVDS settings, but I'm not sure what to try. Has anyone gotten their Intel graphics working in a flashed IdeaPad Y500 with GeForce GT 650M SLI?

Hi!

If you have this error:  

Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.

Please contact the target system BIOS vendor for an option to disable Protected Range Registers.

 

Then download archive Prr.rar from this link:  https://files.fm/u/qfpmwzpsh

Extract this archive, then put both files ( prr.exe and Flash.bat ) into your USB flash drive (where contain your bios file and fpt utility).

Rename your file v204mod.bin  to bios.bin

Then boot from your USB flash drive in real DOS, and execute command:  flash

My bios version is the v2.04, is there any way to use the downloaded bios instead of the original one from the laptop?

Hi!

No, to prepare unlocked bios, you need to use your original file bios dump from your laptop.

Hi, I'm trying to dump it but I'm getting the error 75 fparts.txt file not found. But the file is there!

For creating backup of bios you can use attached utility. Extract attached archive directly on the Desktop and run utility as Administrator (right click mouse, choice "Run as Administrator"). Utility will create archive "results" directly on the Desktop. Post here this archive "results", or upload it into any fileserver and send me the link.

      Hello, I have several Lenovo L530 notebooks, but there is no wi-fi adapter inside. I tried to use my wi-fi adapters, but whti every adapter I have an error "1802 unauthorized network card is plugged in". I have already used all available wi-fi adapters, but no result. I really need professional help and I hope I find it here. As far as I understand there is a way to remove whitelist in BIOS, so here's the file with my BIOS dump.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)

      In this thread you can post your requests for Lenovo ThinkPad L440.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash 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.
