Thanks for the response. I'm not sure what "Backup Fault" is and how to correct it. If you could elaborate some on this, it would be much appreciated.Leave a comment:

Re: Dell 5420 - XMC 25RH256CXIQ Can't read bios
After getting my WSON8 probe, I was able to read the BIOS chip. One concern I have is that each time I read the BIOS and run the command "certutil -hashfile filename.bin MD5", I get a different checksum as a result. Does that indicate an issue?
My BIOS chip is a XMC 25RH256CXIQ PPE46700 01 2121U in a Dell 5420 with the motherboard info as:

Dell 5420 - XMC 25RH256CXIQ Can't read bios
Hi All,
Looking for from help/guidance.
I have a CH341a (3.3v modified) trying to read bios from a Dell Latitude 5420 with a XMC 25RH256CXIQ bios chip.
I have read many articles in this forum including
[URL="https://www.badcaps.net/forum/showthread.php?p=1140467"]https://www.badcaps.net/forum/showthread.php?p=1140467[/URL]
but nothing seems to be working.
When connecting the clip to the chip, the ch341a indicates chip is not detected. The chip is on the board and I have disconnected power and the battery.... -
Re: Dell Latitude 5420 Bios Password 8FC8
Hello All,
I'm pretty much a newbie at doing this but would like to learn the steps needed to edit the BIOS from a system board.
I need help to remove the admin password from the BIOS on my Dell Latitude 5420. In researching this site, it appears I need to first get the bios file. The original SSD is missing from the laptop but I have replaced it with a new one so no OS to work from.
