Hello friends!
I've got a latitude 5431 with no sign of life.
I opened the computer and, of course, someone played with the SOIC8 BIOS (16MO).
I dumped the BIOS and... it is VIRGIN, no data in it!
Could you rebuilt a correct BIOS for me?
Here is the 32MO dump (fortunately, this chip was not unsoldered :-) ).
It is a Latitude 5431 (i7) S/T: 6QVWJR3
motherboard HDB45

So I have to flash BOTH files (16 and 32), with, of course, the modified 32 one?
PS: for the adresses, it is 009230000 to 00A02FFF?
Because HxD Editor does not recognize these adresses ( 0x923000 to 0xA02FFF BUT recognize them with a "0" instead of "x")...Attached FilesPremium supporters get full download access and other benefits.

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
Hello everyone,
I am looking for some expert help to generate a master unlock code for my Dell laptop. In January, I bought this laptop second-hand. At the time of purchase, everything worked perfectly: the battery was in good health, and there was absolutely no BIOS password active. Recently, likely triggered by automatic software/BIOS updates combined with a sudden hardware battery failure (my battery report shows the full charge capacity suddenly dropped from 31,000 mWh to 10,078 mWh within a few days), the system locked up and is now asking for a BIOS setup password. I contacted... -
