Dell Latitude 5500 Bios password

[Markus1741]

Explanation You have the Dell model in which the BIOS was divided into two chips.
The ME region is on the 8MB chip. The BIOS region main bios is on the 16MB chip. Both chips should be close to each other.
Designation on the motherboard I think with UC6+ UC5. I don't have a motherboard schematic for this model.
What rex98 needs is the 8MB BIOS file because this is the only place where the 4 bytes that need to be edited can be found.
Because you don't need a 16MB chip, it shouldn't be changed either.
Maybe I could help.
If you want to get rid of your password you have to upload the 8MB file here, that's the only way to do it.

Fantastic, explains why the file didn't appear to have the right components. Thanks all for taking the time to reply. With the right file the guidance makes more sense. I'll be doing some desoldering and come back when I successfully download the files.

can i get some help? i don't have any physical bios reader/flasher but the service tag is 4M6B163 with the 8FC8 suffix (naturally), unfortunately everyone i see doing it is selling a service costing more than the laptop on the used market itself.

I have a Dell Latitude 5500 with a BIOS password. Service tag is 6NV40R2. The motherboard is an LA-G901P Rev 1.0. Attached are the contents of the two EEProm chips on the board (25Q256JVEQ and 25Q80CSIG) read using an xgecu T56 programmer. Can someone remove the password or provide instruction to remove it?

(edit: added pic of eeprom locations for those that come across this in the future)

enter service tag and update bios after.

Thank you! That worked

For anyone that comes along at a later date and has problems reading the WSON (TDFN) eeprom chip, there is a large central ground pad on the bottom of the chip. At least on some programming adapters, this ground pad can contact the outer data/power pads. See attached pic's. (Note: I've put kapton tape over the central pad in this case to prevent unwanted connections). (please excuse the flux mess - should have taken pics after cleanup). Hope this helps someone.
