Thank you this worked perfectly.
For my future reference and if it is any help to others. It appears that flashing just the 16mb chip is enough. Based on the differences between the locked bios I posted and the bios that [B][URL="https://www.badcaps.net/member/391642-hoaca388"]hoaca388[/URL][/B] had modified for me it looks like he modified two hex values.
Offset: 000C4843
changed from AA to 00

This put the bios into manufacturing mode and allowed me to re-enter the Service Tag. And the...

I have a dell OptiPlex Micro 7010
ST: GCHVY24
This computer is bios locked. I have attached dump from both of the bios chips. I assume that flashing the 16MB chip will remove the password, but I am not certain if i need to wipe the 32MB chip or make any changes to it.
I am fairly handy in a hex editor, but I haven't been able to find any great info on removing these passwords myself. I am not sure if it is as simple as wiping and flashing with a bin pulled from a dell download, any links or resources would be apprciated

Re: HP EliteBook 845 G7 BIOS Pass
Is there a definitive method for clearing these passwords? I did try clearing the nvramactive area on the 32mb dump and the bios log persists. If i understood the previous post, this is the ec chip and should only be necessary to clear on this chip (u367)
Is it situational?Last edited by drewrox2009; 05-23-2023, 04:25 PM.Leave a comment:

Re: Request ZBook 15-G3 Bios Dump

Re: hp elitebook 840 g4 need password unlock
I have a G4 That has a password locked bios also.
I have been scouring the internet on how exactly we can edit the dump to remove the password. Any pointers on where to look?Last edited by SMDFlea; 04-10-2023, 12:39 PM.Leave a comment:

Re: hp x360 not charging battery
it probably did, i have replaced it as well. spend way too much time measuring that area. I was sure there was an issue with it or the passives nearby lol. actual issue was on the other side of the board.
but it was good practice working on a board with no schematicsLeave a comment:

Re: x360 15m-bp111dx Battery Not Charging
Thank you everyone for the help! Turns out it was this component pulling down the clock signal when it was enabled. Replaced with same component and charging is working correctly....Leave a comment:

Re: x360 15m-bp111dx Battery Not Charging
Stencils and ec ordered. i can't find what the bga configuration is on this chip, do you know which adapter i need for my programmer? haven't dug this deep into a kbc repair yet.Leave a comment:

Re: x360 15m-bp111dx Battery Not Charging
Thank you for the response, i did check both in diode mode and resistance on scl line and sda line they were equal, don't have the measurements handy. I did reflow the ec hoping it would resolve any cracked or broken balls however i will order a stencil and reball the ec. I cannot find any great info on the ec. but if i were to replace it do you know if it needs to be programmed.
Last question, Do you know where i can purchase the correct stencils?Leave a comment:
