Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Only modified VBIOS for the ultrabay card is needed. Internal card VBIOS is integrated with the main BIOS and cannot be flashed seperately. This does not cause any issues with SLI, as Nvidia states VBIOS version don't prevent SLI from functioning.

Good to know - I'm just trying to get similar clocks on both cards so I don't have to apply clocks manually all the time. I'll dig through the BIOSes and try to find some that match...

Hi guys,

I fell victim for the power management bug and I think re flashing the bios might help hence a doubt, Will the windows 8 serials get erased if I re flash it with v2.02 (I am already on v2,02) Thanks

I would use RWeverything to view your imbedded win8 serial and write it down for backup. But if you follwed the OP bios procedure, your serial should be fine.

Can someone tell me how to edit my unlocked bios so I can get these stock cores to be the same, not 2 mhz off?

I have flashed on both, and had ZERO problems. You are flashing in a DOS environment from boot disk anyway,

Hey gang, can anyone tell me if the links to the bios on the front page are working? I've got the minimum number of posts (which were legit posts from a year ago when I first modified my bios), but I still get the error: you do not have permission to access this page. This could be due to one of several reasons:... I'm only asking because there's a banner for a forum download conversion listed above, buy I don't see any Y500 files in that section. If someone can confirm those links on page 1 are in fact working I'll suck it up and pay the subscription fee again.

The links from the front page have been moved to the downloads section. But you'll find all current mods in the first page of this thread. You do have the permissions for them, I checked.

4Hi guys I think i have a big problem. I smelled some smoke from my y500 and i saw the battery is started to discharge so fast while im on AC adapter...windows shows its charging but no... Now i can'T really start my laptop (only for some second) the battery indicator is blinking in orange color.

I have 2.02 unlocked bios (upgraded from 1.04)

So can I recover like I upgraded it,just I have to use my backupped 1.04 bios? Before i send back?

I will try out to start my laptop with a weaker charger,(i tried to start without the battery but no success)

Edit: Seems my charger died, it is charging just too slowly (35% in 10hour), I think I have to send back my whole laptop so I still have to recover to my original bios.

Can someone tell me How to do that? And same with the Ultrabay is it enough to run the official 8.1bios update?

So, I recently updated to Windows 8.1 and it messed up SLI and led me to have to do some searching online and find out that I had to flash the VBios with the fixed 8.1 bios from Lenovo, and after I did so, overclocking stopped working, one card overclocks, but the other doesn't. Could anyone help me please? If you need anymore info at from me, don't hesitate to ask

Where do I find that? Could you direct me to a page as this thread is massive, or is there any search feature I can use?

Also, is it one of the ones on the first page of the thread? If so, which one?

After flashing the new BIOS version (2.02 I believe ) windows doesn't load correctly and I get a blue screen stating "critical_process_died". How do I fix this? I'm running windows 8.1 and I have the sli configured y500

First of all go to the bios and load the default settings.

      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.)
