Hi, can i have somebody help with this absolute locked bios, it has no password but absolute is enabled thus it locks the laptop and the option to disable it in the bios is just grayed out.
Any help or guidance on how to do it would be greatly appreciated!

I have tried to remove an admin password and I saved an initial backup of 32MB. After the new "unlocked" BIOS file failed to POST I reverted it to its original state and left it for a bit, and in the meantime, I updated BIOS from the Dell website.
So this christmas when I had more spare time I attempted again, wrongly assuming I had a good backup (I do have a good backup but on an older BIOS version), and even with this file laptop does not boot. The keyboard lits up and the fan spins 100%.

ZIP contains two files - one known good (now it does not work because I reckon the BIOS version is lower than what was installed before I tried the second time) and the second "unlocked" which did not work anyway.

Try this unlocked me clean file from your original Bios file ...

[Virko123]

Hello, behaviour has changed - Fan does not spin and only power button lits, after 10-20 seconds LED starts to flash quickly 5-6 times? and laptop turns off

[Markus1741]

New one ...
