First check this site to see if your HP is supported for the great tool Mazzif has made.

If your model is newer and not in that list, you need to dump your bios, remove password from dump and reprogram bios with modified dump.

For that you need an SPI programmer like CH341A or Raspberry Pi with Flashrom or any other similar programmer. A soic8 clip is also useful so there wouldn't be a need to unsolder bios IC.

When you have your dump, just drag and drop your file on my HPUnlocker...

Can any one help me for cleaning the attached bios HP Elitebook 840 G5...

Hi,

I have recently bought a Laptop that has a Endpoint Security Controller Problem. According to the seller it has just appeared all of the sudden.

Things I have tried so far:
[LIST][*]Restore the security settings to defaults and restart the laptop[*]Disable all the security options[*]Clear the NvramActiveRegn areas (replace with FF) Hex Area 37000-38FF0[/LIST]

Also I have checked the DMI Information which seems right according to the stickers on the mainboard.

Is there anything else I can try?

Hi everyone,

i am facing a strange problem with an HP Elitebook 840 G5. Unfortunatley no board schematics are to be found on this one (COMPUTRO-6050A2945601)

The laptop runs at 0.4 GHz and is always in BD PROCHOT protection. Even in the BIOS it shows 400MHz CPU clock... And same issue when booting a Live Linux. So I am pretty sure I can rule out problems with the OS. It must be lower level.
I've been researching this behavior the past 2 days and tried EVERYTHING I could find on that topic.

What I noticed playing around is that when I disable...

Hello, I have a HP elitebook 840 G5 and it was locked by a password, after removing it, it seems that it was either locked or got damaged (despite taking care). As a last resort, I would like to ask you for help if we/you can flash a new BIOS eeprom so that it would work.
Some information that it might be helpful :

Hello, I recently got two locked HP EliteBook 840 G5, I've seen that this tool supports them - however I am not able to get it working.
When I dragged the locked dump onto the exe, I get a supposedly unlocked file, but when I flash it, the BIOS is still locked.

I am flashing/reading from the 32MB chip.
Here are my locked dumps....

Hello, I am attaching two BIOS dumps from two HP EliteBook 840 G5 laptops - I was unable to reset the BIOS password using these tools:

Hey there,

I have got a HP Elitebook from a friend. It just starts with a black screen and loud fan. He tried to unlock the BIOS. Strangely I can't get 2 same reads out of the 32 MB Chip.
If I put another Chip in I can read and write on it without any problems. So I suggest it is a bad chip.
I only got a faulty readout of the 32 MB. The original dump and the one that was flashed is sadly gone forever. But maybe someone can make a working image again out of it?

Thanks a lot in advance
