Lenovo Thinkpad T480 BIOS and EEPROM request

Re: Lenovo Thinkpad T480 BIOS and EEPROM request

Hi all, this is my first post in this forum.
I have a problem with Lenovo T480. I bought this laptop with faulty motherboard i am trying to fix it. Motherboard when powered up, plays a melody and after a while shuts down. Display is blank.
I suspect the bios chip, because I see traces of tampering with this chip. I took a from BIOS chip and EC. Could someone take a look to see if the content is correct?
Maybe some additional advice on what I should check?
Thanks in advance!

Post the laptop serial number - https://www.badcaps.net/forum/showthread.php?t=103570

Is there a tamper switch on the T480 ?

In this case flash back your original dump, power up the laptop then enter the bios and set supervisor password, restart, power off, dump the bios chip again and then patch the dump. Follow the "how to use the patch" steps.
After that you can be able to disable Absolute.

You have Absolute enabled in the bios, but not bios password, or you have both enabled?
