  1. 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
  2. Dear Klem, I kindly ask you to modify the bios of my T450s. The bios is already dumped via CH341a SPI programmer and can be found here. --> Bios dump Please remove the whitelists for Wi-Fi cards and for Displays and unlock the hidden additional menus and settings in bios setup menu. I already tried to remove the whitelist for displays but had no success. 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? Any special instructions / bios settings for flashing your modded bios back into the chip? Like disabling TPM, etc.? Thank you in advance for assistance. Regards, Greg
