DL470 NM-B021
Rev: 2.0
Serial number: PF-0VNPA3
Type: 20J5-S1FL00

Corrupted the original bios and have been flashing a few recommended ones, Enter key seems to not work and Windows not picking up correct drivers. I don't have original BIOS :/

EDIT: Attached dump of original bios, it would turn on but backlight wouldnt even turn on, basically didn't POST.

Answering to myself...

Get an EC content from another L470, transferred only the DMI info from my backup and Computrace is gone.

patch doesn't work for me in lenovo thinkpad t495 on amd platform
after writing to memory and soldering computer makes strange sounds as if bios doesn't work. I'm attaching dump file maybe someone can help me and send file with patch and it will work. I tried several times but unfortunately computer doesn't start on this bios.

Off topic, this thread is for the l470 as it says in the thread title. Please post your request in a T495 topic.

Hi, I have a Lenovo L470 that does everything apart from POST - it powers on, bleeps if there's no RAM installed, all voltages are present, the CPU warms up and the battery charges. My working assumption is therefore a corrupted BIOS.
It would therefore be great if someone could take the configuration information from the attached BIOS dump and copy it into a fresh image for me.

The laptop is an L470 Type 20J5 with a NM-B021 motherboard, serial number PF-0UY199

Thanks!
