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.

So it's 2022 now, and 802.11ax / Wifi 6 is the new standard. Wondering if anyone has successfully tried a Wifi 6 card (esp. one w/ 160Mhz support) in an unlocked Y500? After upgrading to an SSD my 9 year old y600 is still going strong, but the Wifi performance is a serious annoyance.

To answer my own question, a Wifi 6 card works fine. I put an AX210-based Wifi 6E card in my y500 (after doing the bios mod), and it works great, as does the card's bluetooth capability ... I don't have a 6ghz capable router to test with, but since 2.4 and 5 work OK, I'd assume 6 would too. The particular card I got is this: https://www.amazon.com/gp/product/B09CDFV2CL/. I had to download drivers directly from Intel, Windows did not already have them (in fact, neither did windows update). I had to dig out an Ethernet cable, I recommend pre-downloading if you want to avoid that.

 

As much as I love Lenovo's build quality, this will be my last Lenovo laptop. I did a little more research and it appears that they're still doing whitelists to this day ... and well, that's total BS. If it weren't for the people who put all the hard work into figuring this out, I'd be stuck either using a USB dongle or getting a new laptop. Thanks, everyone!
