Hi everyone,
I have a Dell Latitude 5430 (Service Tag: 4HK5GK3) that originally had a BIOS password.
There are two BIOS chips on the motherboard. I identified the main chip and successfully read and saved its contents using a CH341A programmer.

Here's what I did:

1. I read and backed up the original BIOS from the main IC.
2. I then erased the chip and flashed a clean BIOS file (no password) from the internet.
3. After installing the chip back into the board, the laptop no longer powers on — only a brief power light when pressing the power button, then it shuts off immediately.
4. I tried to recover by reprogramming the original BIOS dump back to the chip — but the laptop is still completely dead. Same behavior: power light flashes briefly and turns off.

Can someone please help me:

• Determine what went wrong?
• Suggest how to recover this board?
• Is it necessary to flash the second BIOS IC as well?

I will attach the original BIOS dump I took from the board before any changes.

Thanks in advance!

You made a bad backup, it`s all zeros, that`s why it wouldn`t work when you flashed it back..

Not this chip, look for the chip with the number 256 on the back.
