HP Elitebook 840 G6 Admin PW Help

Hi everyone,

I have an 840 G6 laptop with admin password.
I have read the BIOS (32MB) and ran HP Unlocker over it, but the admin password is still there.

I have done this before on an 840 G5 without issues, but it's not working on 840 G6.

I have read on this forum about 32MB and 16MB BIOS chips. Where is the 16MB chip?

I have included a photo of the chip which I read from.
I have also included the original dump, and the unlocked dump which didn't' work.

Please let me know what I am doing wrong.

Thanks

So there is another chip on the other side I need to read?

I have taken the motherboard out, but I don't know which chip is the 16MB.
I have attached a photo.
Please let me know which chip it is and how to read?
Thanks

Re: HP Elitebook 840 G6 Admin PW Help

send me dump file

The dump file was provided here
https://www.badcaps.net/forum/showpo...76&postcount=6

But the problem I am having is that I have taken a dump of the 32MB chip and scrubbed it, but it doesn't work. People tell me there is a 16MB chip I need to dump, but I can't find it. Where is the 16MB chip?

Re: HP Elitebook 840 G6 Admin PW Help

That's what I did. In 1st post I posted both the original and scrubbed 32MB dump, but there is still bios pw on it.
In 2nd post, people say I must find the 16MB chip too.
Are you saying I only need to program 32MB chip only?

the laptop has two bios, one of 32MB and one of 16MB ... if you don't rewrite both of them you won't get rid of the password ... look for the second bios chip (16MB, it can be on the other side of the motherboard) , and write it with what I sent ... don't forget to make a backup copy of the 16MB chip before writing it ..

I am unable to find the 2nd 16MB bios chip. I have taken the board out and looked on the other side but can't see anything which looks like a 16mb bios chip.

I have included a picture of the other side of the motherboard. Can you help with locating the 16mb chip?

Re: HP Elitebook 840 G6 Admin PW Help

U366 must be the second chip. Can't see the markings but looks like that.
You can write here the markings of the chip for confirmation.

I think you're right. The chip is IC25LP128 so it looks like the 16mb chip.
However there are no exposed feet/pads, so I can't solder wires onto it. I don't want to remove the chip to read/program it. Very annoying.

But thanks everyone for their help
