This is a Dell Latitude 5591, ST: B168QQ2, board# DDP80-LA-F712P Rev 1.0 (A00). I did quite a bit of searching because I'd really like to learn this skill for myself, for the future. I didn't find anything conclusive, though, so I was hoping one of the geniuses here could unlock this BIOS for me. I would so greatly appreciate it....

This is, I believe, the BIOS chip for this dell latitude 5591. It has a locked admin password on the BIOS, so I need to reflash, but I'm wondering which adapter I need to use with my CH341a. None of my board seem like the correct adapter.

This is the topic of DELL LATITUDE 5591, you are asking me to unlock DELL PRECISION 3560, please post in the right topic.

By the way your file is broken, please read the chip again....

Hello,
I would need a BIOS for DELL LATITUDE 5591
LA-F712P
DDP80 LA-F712P
REV: 1.0(A00)
Service tag : 87VQNF2
Here is the dump of mine, but I am stuck with the boot password and no luck at changing it

Hi everyone!
I have a Dell Latitude 5591. It has a strange problem:

First, when the WLAN card is plug in, it will not power on when press power button, even all voltage is up (19v, 3v, 5v, 3valw, 5valw)

When I remove the WLAN card, it will start nomarlly. Then I power off and re-insert the WLAN card, it still work normally.

But, if I left it for 3 or 4 days without the battery and adapter plugged in, it will not power on, and I have to repeat the above sequence.

Sometime, when it not power on, I just unplugged the battery and adapter, wait...
