You mean I should install the original BIOS? Does that make sense? I don't have many more attempts because of the solved PAD 5.

I wrote the dump on the chip. The device behaves exactly as before. Since I am not here for the next 4 days I will keep the NB on all the time to see if the state has changed. Unfortunately, with the CH314, I can't program on the board. Some component on the PCB pulls away so much power that I just can't get the dump clean on the chip. That means I have to get the chip out and in every time I try. And because an accident rarely comes on its own, the pad of Pin 5 has dissolved itself from the PCB. I'm gonna have to figure something out on the next solder. I hope the notebook wakes up again.

Can someone help me? I programmed and checked the patched dump. Battery, HDD and BIOS battery disconnected.
When you plug in the power supply, the power button flashes 3 times. After switching on, the power LED lights up,
goes off and comes on again after 5 seconds. That's it. No LCD, nothing? What can I do?​

Sorry!

ALL RIGHT. I bought a CH341 and read out the BIOS. Can someone patch the file for me? Thank you....

Thank you for responce.

Before I found this forum, I bought a so-called "password unlock chip" and soldered it to the board.
Now the notebook tells me something about wrong UEFI variables, shows me the hardware ID and expects a key.
I also don't know what happens if I just press Enter. I don't want the whole thing to become worthless....

Hardware ID: 458478389
Key?

Can anyone help me please?

Hi.

I have a E490 Device. The DXE Driver shows me 458478389 as Hardware-ID.
Can anyone generate the Key for me?

Thanks
