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?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Request ZBook 15-G3 Bios Dump
If you don't mind me asking, What did it take to Get rid of the MUD message? Just removed a password and running into this also, haven't seen this one before

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.

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 schematics

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....

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.

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?

Re: hp x360 not charging battery
I am having this exact same issue on a different board. 15M-BP111DX same bq24737, no schematic available for this board. Not sure where to look, and pulling my hair out!
