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

Recommended Posts

I picked up a y510p that came with 3.05 bios already on it. What did they do to that version of the bios that whitelist can't be removed? If I go with an older version of the bios will I have any problems with my 755 sli?

I just wanted to add my thanks to SVL7 for the whitelist mods. I have an early Y510P with the 1.07 BIOS. Experiencing the excessive battery drain problem when shut down, and sick of el-cheapo WiFi card.

I found the 3.05 BIOS flash here: http://forum.techinferno.com/lenovo-ibm/5979-bios-update-y410p-y510p-74cn44ww-v3-05-a.html

Then I backflashed it to 2.07 here (probably could've skipped the 3.05 update first, but didn't want to risk it): http://forum.techinferno.com/lenovo-ibm/5405-please-make-modded-y510p-bios-based-74cn44ww-v3-05-a-2.html#post77265

Then ran the whitelist mod on this thread so I could run my new 7260AC WiFi card.

The updated BIOS fixed my excessive battery drain problem. I had tried everything prior to this. Removed the wifi card, removed the SSD, disabled WOL, disabled fast startup, new battery, Energy Management app, etc. Nothing fixed it until I flashed a newer BIOS, and I was losing at a rate of 1-2% per hour when completely shut down.

BTW: Disabling Bluetooth on the 7260AC card solved the sleep problem as well. Not ideal, but I can live with it for now.

How do you disable the bluetooth? I tried device manager and disabled the bluetooth there, but that didn't solve the sleep issues... Is there another way to do it?

Thanks

That's exactly what I did. I installed the latest Intel wifi and bluetooth drivers for the card, and then went into the device manager, highlighted the "Intel® Wireless Bluetooth® 4.0 + HS Adapter" and disabled it. Seems to sleep now, but I didn't wait around a while to see if it remained sleeping. Basically I was just disabling different wifi features and hitting "sleep" over and over to see which thing did the trick. For example, it sleeps just fine if I put the laptop in Airplane mode (running Windows 8.1). From there I just started disabling things/re-enabling things until I got a combination that allowed it to sleep.

i didnt do anything else other than i turned off bluetooth under airplane mode. it works but half the time. to sleep it might take one or two tries.

@ all the 3.05 requests: I tried something a while ago, if I remember correctly the problem is that all flashing of unsigned code is blocked in 3.05... so the only way would be downgrade to stock 2.07 and then flashing a modified 2.07, or flashing a modified 3.05, but the problem then is flashing the newer EC... Anyone in for some testing?

EC can not flash by oneself.It do not store in the SPI IC(2M 4M).

I used the spi programmer,EC can not change.

The EC program must store in the IC(IT8586E).

Well, technically it can be flashed separately by software, I just don't have a system to test that.

OK, so i if good understand... When we downgrade to 2.07 - EC is also downgrade to right for 2.07... and when i upgrade to modified 3.05 the EC still stay the same for 2.07?! Why EC aren't upgrade with 3.05? Please can You explain it for me?

The problem is the only way to flash a modified bios is currently using the way I described in the first post, and that doesn't flash the EC, only the bios.

If you use the official updates (for downgrading or upgrading, doesn't matter) then it will flash the EC as well, but only then.

OK.. so... If i downgrade my stock 3.05 to 2.07 with bios from here:

http://forum.techinferno.com/lenovo-ibm/5405-please-make-modded-y510p-bios-based-74cn44ww-v3-05-a-2.html

my EC stay still with version compatible for 3.05 and then if you mod the stock 3.05, when i upgrade to this version (with your way) my EC be still right for 3.05. Probably everything would be fine?! Or maybe i'm wrong?

No, your EC will most likely be the 2.07 one afterwards. Well the only way to find out is to try... Usually a downgrade also flashes the older EC version.

Noob question here, my Lenovo Y510p is currently running on BIOS version 2.02 and I have no idea where I could possibly get to one of the BIOS versions that is supported (preferably v2.04 I suppose). Lenovo's website isn't helping much either and it just doesn' t seem to exist on the entire internet \rant

tl;dr: how do I get from version 2.02 to 2.04 so that I can finally use the whitelist mod, where can I find it?

Yes, please.

But first of all, can you tell me whether the EC gets flashed when downgrading the bios with an official update? I'm pretty sure the answer is yes, but I can't verify that.

You can use the update to 2.07 and then flash the modified 2.07.

I'm trying to find that version as well, but all I came back with is: http://forum.techinferno.com/lenovo-ibm/7158-y510p-2-07-bios-download.html

Do I really need to upgrade to v3.05 first in order to downgrade to v2.07? It sounds really illogical and risky. Does anyone happen to have the BIOS version 2.07 stock installer?

      Hey allI, I need help  with modding my BIOS. I was wondering if anyone could help me mod my BIOS to unlock the 'Advanced' tab which I don't have on my InsydeH20 F.52 Rev 5.0 Bios? Thanks so much and I look forward to your response! Laptop: HP Pavilion x360  ba109tx

      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.

      Hey guys, I have an Alienware m14x R2, and I have been trying to get access to the BIOS so that I can change the boot options (Everything is locked, I am unsure if someone set a password of if these are locked by default).I've tried updating the BIOS, and resetting the CMOS and nothing has changed this. Would anyone know if there are other options I can explore? Thank you.
