I've entered password multiple times but do not receive a code. This is a Precision 3551.

I am using a CH341A programmer on Win10 with AsProgrammer application to dump the file. I've dumped it twice and verified the MD5 hash. This is the file that it is giving me. Is there another way of doing it? I have a Linux machine if needed.

Use NeoProgrammer, it is not necessary to install the drivers again, just click on NeoProgrammer.exe then detect the chip automatically.

Re: Dell Precision 3551

I've dumped it multiple times with the same file size result. Is it possible that I have the wrong chip? The chip is a Winbond W25Q80DVIG. If that's the wrong chip can someone please tell me the right one including location on the motherboard?

@Coder2021
Exactly the chip is wrong! Look for something like 25Q128 or 25Q256

Dell Precision 3551 bios unlock

Hi,

got laptop with locked bios, what I want is just unlock the computer. Up to now I looked all over the internet and done some tinkering with bios flash, but without luck.

First question, now laptop only reacts to power button press with amber led, nothing else.
It's possible that this reaction means something else than wrong bios?

Can somebody help me with bios mod?

In attachment are dumps from all roms on motherboard

Here's your Unlocked BIOS, hope it works fine.
If this is your Original BIOS, the device should works without any problems. Otherwise you may need to change the BIOS Chip or look for any messing components nearby your BIOS Chip.
