Lenovo ThinkPad T440p / T440s/ T540 unlocked BIOS menu / wlan / wi-fi whitelist mod

Recommended Posts

In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.

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.

Important!

For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!

 

Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

Hello Klem!

I recently acquired a Lenovo T440P, and would appreciate if you could help me get the WLAN whitelist removed, as well as the Advanced Menu unlocked.

I used a SPI programmer CH341A to dump my BIOS from W25Q32FV chip.

The dump i sent you via PM.

Thanks, and I appreciate any help!

Hi, Klem!

I used my ch341a_spi to dump my bios from my W25Q32.V chip in my T440p. I just sent you the BIOS dump via pm. Would you be able to modify it to get both the unlocked BIOS menu added and the WLAN whiteless removed?

Thank you!

Hi,

 

I have Lenovo T440P, It has been locked with Supervisor password on BIOS chip winbond 25Q32FVSIQ (1414). Is there a way to remove the password, so that i can enable Wireless LAN in BIOS setup.

 

Thanks,

Karthik sha

Hi!

No, unfortunately unlocked bios can't help you with Supervisor password.

Hi, I've got the SPI programmer and tried to dump the bios, but the clip was constantly 'sliding' off of the chip.. I'd assume there's enough space to get a grip without removing the whole base cover, but right now I am not sure if the issue is with my fatty fingers or do I really need to disassemble it to get the clear access to the mobo?

Hi!

Unfortunately, I can't remotely help you connect the SOIC8 clip to the BIOS chip. If you can't connect, and you see that something prevents you connect, you can try to disassemble the laptop.

Was rather thinking that someone who dumped it would chime in and tell whether they had to remove the bottom base or not :) Thanks, will tear it apart tonight and will get back to you when I have the dump. Thanks! 

 

OK I was able to dump the bios, send you a PM.

Hi guys & modder,

 

I am about to buy SPI programmer and test clip to flash my bios. I am doing this to enable my laptop to install egpu.

My lenovo t440p is the one with core i5-4200u.

 

Just checking if the thread is still active (if there is any reply after my post :p)

 

I'll attach the dump later.

 

Thanks!!

Hello, did anyone have any issues using flashrom via linux seems... ch341a_spi is supported https://www.flashrom.org/Supported_hardware#Supported_chipsets

 

Curious if all these cheap ch341 programmers are all the same, and behave the same for flashrom to pickup the usb device correctly.

 

I also found this debian based program https://github.com/setarcos/ch341prog - but if the more widely used flashrom works, may as well use that.

Hello Support,
 
I have a T440p Lenovo laptop, and forgotten the BIOS Super password, please can you advise if BIOS password can be removed?
 
What will be the procedure, will it require opening the laptop motherboard etc or just through software programming?
Can I do it myself if you provide steps and instructions?
How much will the service cost and how much time will it take to unlock the laptop?
 
Thanking in advance for your response.

Hi, I'd like to upgrade my wifi card and access the hidden bios settings.

 

I have uploaded a bios dump here: https://www.dropbox.com/s/kqkkap4vcptze6o/t440p.zip?dl=0

 

I've upgraded the CPU to a 4810MQ already and plan on installing OS X. Please advise if there are any other BIOS tweaks you would recommend.  Thank you so much for your help!

      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.
