its easy you just need to combine the two bios 8+16. before cleaning. and it would be good.

thank you, but still can not disable absolute

Hi all. There is a DELL Latitude 5400
MB LA-892P Rev 1.0 (A00). Came to me with a problem that takes a long time to turn on. After pressing the button, 23 seconds pass until the image appears. The BIOS chip has already been flashed. I don't have the original dump. Can someone help me with this problem? Here is the dump in the laptop.

It was solved by simply cleaning the ME region.
