In this thread you can post your requests for Lenovo ThinkPad X250, X260.

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.

Hello!

I bought an X250 with Supervisor password. I was able to access most of the settings in BIOS but not Virtualization. In my desperate attempts to somehow reset the Supervisor password, I have entered it 3 times, of course the wrong one and then I was locked out of Windows and BIOS with the error: 199 system security - security password retry count exceeded. The only thing I can do is to enter the correct password which of course I don't know.

 

So, my kind request, if someone could please help me modify my BIOS dump in order to at least reset the incorrect password count so I can at least use my laptop like before, even with the Supervisor password, that will be great.

If the Supervisor password can be removed, that will be perfect.

 

Here is the BIOS dump: https://www.dropbox.com/s/0qyqdnakn7fsvcs/bios1.zip?dl=0

 

Thank you!

Not even with that flag that tells the BIOS I have entered the password to many times?

 

Thank you!

Hello Klem, I'm searching to upgrade my x260 with the following drive:

 

SSD TOSHIBA RC100 (240 GB - M.2 2242 - PCIe 3.1

 

Would this be possible with an unlocked bios? 

 

Thank you very much in advance for your guidance and assistance!

Hello Klem, thank you for the speedy response. 

 

Tried out the Toshiba drive but cannot get it recognized to install win10. From other sites gathered that Lenovo only allows whitelisted wifi cards. So I was wondering, if your modded bios will allow to recognize the drive and use it as a bootable m.2 nvme drive. 

 

Thank you again!

Ok. Now I understand. Unfortunately unlocked bios can't help to recognize SSD in m.2 slot. It's Lenovo design for x260 laptop model.

      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.
