Re: HP Elitebook 840 G6 Admin PW Help

I think you're right. The chip is IC25LP128 so it looks like the 16mb chip.

Yes, it is.

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

The chip is WSON-8 type, so yes - you must desolder it from the board first, then use the suitable adapter to read/write the chip.

The 32mb chip is also a WSON-8, but it had pads so I was able to solder wires to it and read/write it without removing it from the board.
The 16mb chip however doesn't have the pads so I will have to remove it. But I don't have the adapters to read it.

So instead of trying to remove the chip and reading/writing. I just want to break the laptop.

I have wiped the 32mb chip, but after a few reboots the machine restores the bios again.

What can I do to damage the laptop so it gets the motherboard replaced but not void the warranty?

You can see where the traces go from each pinjust solder to the nearest point,resistor etc

I've looked at that and I don't have the skills or equipment to do that.
You can trace the tracks if you zoom in with a camera, but they lead to the smallest SMD I've ever seen, and I am not able to do that kind of work.

I did use a heat gun and removed the chip. I soldered wires to but unable to read or write using the programmer.

So the lesson is the HPs with 1 bios chip is fine and I can do those no problems at all ... the ones with 2 is way beyond my skills.

Thanks again for your help everyone

Re: HP Elitebook 840 G6 Admin PW Help

What model is your programmer

CH341A I think.
It's the cheap one you get from Aliexpress

NeoProgrammer, a good CH341A software alternative supports the chip - https://www.badcaps.net/forum/showpo...04&postcount=7 .Use the IC search,just type in 25LP

unlock tihs 840 g6

try ... you still have a 16MB bios chip on the board, look on both sides of the motherboard..don't forget to make a backup copy of the 16MB chip before writing..and replace it with what was sent ..
