Thank you very much for your support.
I tried using the tool in the link, but it shows a red "Intel Signature" error.
I tried both files for both chips. But both show the same error.

I've seen two other people reporting this, but I haven't been able to find a solution anywhere. Can you help me with the application or the password?

Thank you again....

The computer boots and works correctly, but it has an Admin password in the BIOS. I've attached the BIOS data and files:
Model: Lenovo D15U001 OptiPlex Micro Plus 7020
DP/N: PDM7G A01
Service Tag: 5QVQW34

Can someone help me remove the password? Thank you very much....

As I recover dumps, I'll upload them. I'm still planning to extract the one from a 1,600€ BenQ monitor...https://I'm attaching the file for t...50m-dump[/url]

I also have the XGecu T48. I'm not really an expert on this, but it seems the RTS545x uses I2C/SMBUS, and the XGecu has some limitations in this regard....

I was finally able to easily read and write an RTS5450M!!!
I purchased an Alexsof RTS5450M configuration board and my SVOD4 programmer, but it's compatible with other programmers.

You can find that board here: [url]https://alexsof.com/product/rts545x-adapter-for-type-c-controller-firmware/[/url]

Be sure to check out the website because there are other resources, such as the MPS phase controller programmer or the DDR4 test, that are super interesting.https://I was finally able to easily...guration board

I am in the same situation. I need to program a RTS5450M for a BenQ SW271C-B monitor. Does anyone have any information on this? Thanks.

After trying with another SPI_BIOS, the computer no longer gives an image and has been left with a fixed consumption of 300mA without an image.
In the meantime, the firmware of several devices in the system was updated. I think there is now a corruption between SPI_BIOS and EC_BIOS.
I am attaching my 2 files in case someone can help me. Thank you very much....

First of all, I want to thank you for your help.

I have copied your BIOS and entered the BIOS with F10 to restore the default values. The computer, on first startup, restarts a couple of times with the "HP WOLF SECURITY" logo and does not obey F10. After 2 or 3 restarts like this, I do get the message to enter the BIOS. But at that moment it [B]asks me for the BIOS administrator password[/B]. Therefore, I cannot do the restore to defaults, nor restore the security options.

I tried to follow the procedure with BCU. The get command works and creates the bios.txt...

Hi everyone.
Can anyone help me with this BIOS? It has an administrator password to enter BIOS.
But for the rest it works fine. It enters Windows and does not show any hardware with errors.

Attached are the computer data:
SN# 5CD3528LD4
ProdID 736W6AV
HP EliteBook 650 G10

Thank you for your support....
