Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

This is probably a dumb question, but i figured better safe than sorry with a thousand dollar laptop.

Mine shipped with bios v 2.0. I used lenovo's (leaked) update to go to 2.02. I am ready to flash the modded BIOS but the only one i can see to download is 2.04. It looks okay from the instructions but i just wanted to confirm that upgrading from 2.02 stock to 2.04 modded would be safe.

Thanks! :)

Yes it's fine that's what we all did.

I just got my laptop back from sending it in for a repair under warranty. It had the modded bios and the sticker covering one of the screws was scratched off, but everything went smoothly and nothing happened to the warranty. The rep (in regards to warranty) said that the laptop is yours and you can do whatever you want to it as long as you are not responsible for whatever the problem is.

Good to know! Glad you got your problem sorted out. If I ever do send my laptop in for repair (keeping fingers crossed it won't happen) I'm still gonna flash back to stock beforehand.

So, I send in my laptop today or tomorrow for a dead GPU. Is there any way I can get it back to stock before then?

Hello,

I messed up my computer (Y500, came with windows8). Long story short, I had to reformat everything. Now I'm using windows7 which is not compatible with the cd-key embedded in the BIOS, and it won't let me activate my windows7.

I am wondering if flashing the bios in the method described by the first post would fix this issue, and make the computer be able to accept other windows OS (like windows 7)? If not, how should I proceed to fix the issue? I have tried and failed to locate a valid windows8 iso online ;(

I have the recovery discs just asked them at lenovo and got them. It are 4 disks you can even do a clean install with them without all the lenovo crap. So just try and get the recovery disks.

Can somebody tell me where it leaves the backup bios, Maybe i'm doing something wrong. I extract Fptw64.zip to a new folder on the desktop and i execute the backup.bat as an administrator i don't get errors but i cannot see a backup file of my bios.

Also tried it with the command the box closes but does not leave a bios file in the same folder i put the command in the box that you get when you open fptw64.exe

Nevermind it is working now.

Hi just saw this thread after buying a y500 in june, I'm tired of the bad wlan card and want to switch it by getting rid of the whitelist. My BIOS version is 2.03, will it be safe to do this flash? Also any downsides to doing this flash? I have put Windows 7 on my computer instead of windows 8 and I have the 750m sli version if that matters.

Or just dontate $5 to a WONDERFUL community that I wish I found earlier. Anyway thanks much, I tried a manual vbios flash via dev files from nvidia. To no avail all I did was lock down one card. This should work so wish me luck! Time to hunt for my usb bootable drive ha.

750 is almost identical to the 650m ( same chip ). And I run windows 7, should be fine. I will let you know once I finish it.

So you may want to confirm the vbios numbers 750 vs these ones. I got this to all go fine with the easy to follow instructions. Windows 7 works prime with this bios update (just remember to change secure boot when you update bios as it defaults settings).

I highly recommend you reading the instructions. That's kinda crucial when it comes to flashing and you're not familiar with it...

Run that program in boot, make a usb drive, or any sort of drive bootable with the information and programs provided. This is sort of a sandbox for the bios to update.

Thanks guys svl7, bpendz and bobfig! I haven't done the BIOS or DOS things before, so i don't know i have to boot the USB in to DOS mod (I reread it carefully but i missed this part.). now i have already mod the bios successfully.

and bobfig. your video is awesome. If i had it earlier i wouldn't take so much time lol (but it was a good experience though).

svl7 you're my hero :D

and after i moded the bios, i still need to mod the ultrabay to get it overclocked to +135MHz, right?

I have a question..

I've got a Y500 with gt650m sli and now the 2.00 stock bios.

I want to flash the both gt650m cards to overclock it. (integrated and the ultrabay one)

The instruction is saying "Flashing the ultra bay 650m - only for SLI users with BIOS v2.02" and

"The modified BIOS v2.02 also contains a vbios"

What shall I do now? I can't see a 2.02 custom BIOS under "Attached Files". Or should I flash the 2.04 BIOS and after that the OC ROM for the both GT650m with the nvflash-tool?

Or needn't I flash the gpu bios after flashing the custom 2.04?

Sorry for my bad english and please help me. :)

Yes you have to boot the mod rom to the vBios for the ultrabay card (as it isnt internal it is an external pci card (technically).

Then BAM you are done. These cards can push quite a bit, but find the sweet spot. Keep temps around 70c at max load, dont overvolt, and optimize the control panel and your games.

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.
