Hi


I tried to read through but frankly I can't get what exactly I need to do in order to unlock it
Model: Dell Latitude 3540, I5-4200U, 4GB DDR3, 500GB HDD, 1080p screen, AMD 8850M GPU
this is the bios

Currently, the cpu and gpu automatically underclock considerably if both are under load, although the temperatures are good (around 60C-70C). I want to be able to change it, will it be possible?

Trying to set clocks through Intel XTU and MSI Afterburner didn't work.


Many thanks!
please advise
anyone?

Hi friend,
I want to start a New Way to pass Mods to users :

AutoMod ... How to use ?

1. Mode Sleep Bug (S3 Vulnerability) Mode :

Unpack the file and go into the folder then you will find the ".bat" programs, Dump.bat - Patch.bat, Write.bat

Form the folder execute the Dump.bat program by double click on it and get the "biosreg.bin" file, then execute ar same manner
the Patch.bat program and you'll get the "biosregmod.bin" file and at last put you laptop into a Sleep State (Suspend mode) ,
just close the lid for 5 minute.
Then open the lid to wake-up your laptop and execute the program "Write.bat" , it will write the bios mod !

Summarized :

A. Make a bios backup >> Dump.bat
B. Patch the backup making modifies >> Patch.bat
C. Write back the mod after suspend laptop activity (Sleep Bug) >> Write.bat

If Mode 1 will not work then use the Mode 2 !!!


2. Mode USB Stick Flash For Error 28 :

Unpack the file and go into the folder then you will find the ".bat" programs, Flash.bat

Update from pure DOS with USB-bootable stick
See how to make one here:

Copy the "Modified" folder contents into the stick and boot in DOS mode and
Run Flash.bat to update.

Don't touch Video Settings or Disable Video Card It will Brick laptop !!!

I'm trying to unlock the bios for my latitude 3540 for the exact same reasons as the topic starter of this thread and stumbled in on this topic.

Sadly most links are dead and I can't find a proper patches.txt file.

The latest bios version is A08 for this machine and the modified file in this topic is only A04.

So I would like to patch it myself but I don't know where to start to get a proper patches.txt

Can someone please guide me a little?


This is the latest official bios update from the dell site.
