Dell Latitude 5280 BIOS unlock?

[ordinateur]

Hello great people from the most respectable forums in the world.

Bought this laptop in defective state with BIOS password active, and after fixing some problems it had in the board wanted to ask help for removal of the password if somebody can help me ?

I have read the BIOS chip W25Q128BV@WSON8 which is 16 MB in size, I hope this is the corect chip that I should read, and attached here that BIOS backup also a picture of what the laptop asks on screen.

Thanks very much

Thanks bro, it worked by original site just by exchanging the letter 'Z' on keyboard
So the password was CpZ30ZW6Ltt2L085 but after trying also your suggestion and saw that it is not working then I did exchange the letter Z and it worked.

I thought this Service tag can not be done via Calculation


Thanks very much

If the BF97 suffix doesn't work, why you don't try with the 6FF1 suffix ?

Try the 2 password one by one.
First one: Q25y2rqmb9E91GGG
Second one: FINr8768M4NJyJQ3

Use external US Keyboard (QWERTY), be careful with Upper and Lowercase Letters and Hold Left Ctrl Key Then Press Enter Twice.
