I already tried to remove the whitelist for displays but had no success.

Hi!

Have you already replaced your display with a new one? And what is the problem now with the new display?

Everytime I start the T450s I get the 5 beeps-5 beeps error and disabling the TPM security chip in bios does NOT solve this error. Does this problem exist with your modded bios too?

This is normal, because this laptop model have special TPM/Security chip, every time when laptop start, this chip will check special RSA signature.
When the BIOS integrity test fails, a sequence of 5 whistles is issued twice at boot.
After modifying to remove whitelist (enable unauthorized WI-FI cards), enable advanced menu, etc. the BIOS can't pass the integrity test (because bios was modified), and therefore sequence of 5 whistles is issued twice at boot.

In this case, I know only these ways (sometime it's can help, but sometime no) :

Pull out CMOS battery and wait 5-10 min to reset NVRAM data.

Set (in bios setup menu) TPM to Inactive (not to Disabled) after flashing.

Set (in bios setup menu) Security chip to Disabled.

Set Intel AMT module (in bios setup menu) to Disabled.

Set Anti Theft Module to Disabled.

Set Computrace (in bios setup menu) to Permanent disabled.

Dear Klem,

 

Thank you for your reply and for your help.

 

1. I already replaced/upgraded the display and I have no Brightness control. I'm using Windows 7 x64.

 

2. I understand. So, I guess I will try these steps as soon as I have the modded bios flashed back into the chip.

 

If I remember correctly TPM and Security Chip are the same in the bios menu security tap. Do you mean by Security Chip the Secure Boot Option?

 

Regards,

Greg

Hi everyone!

I'm new on this forum. I own a Thinkpad T450s, which I want to turn into a Hackintosh. So I have extracted the bios with a raspberrypi. I want to mod the bios in order to get advanced option and to obtain DVMT pre-alloc settings to 128MB. I'm willing to donate if someone can make the neccessary modification on my file.

Thanks a lot,

Sofiane.

Hi!

Yes, you can send me (via PM) your bios dump which was made using any SPI programmer (like CH341A), or upload it to any fileserver ( for example https://www.sendspace.com/  )  and send me the link.

Just read the first post of this thread.

Hello, today i did the whitelist succesfull for the LCD.

Only problem now is the 2 X 5 Beeps at every cold boot.

The options for disable the security from KLEM didn`t work for me.

I did this options after flashing the new bios-file.

 

Anybody with options?

      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.
