Hi Everyone I have a 3 Hp Zbook 15 g5 with motherboard DA0XW2MBAG0 REV-G, the problem at first was because the audio driver was not installed in the bios, the audio was working but in Windows it was not installed, after many attempts to fix it, I thought it was a bios problem because the IC was made elsewhere. I try to program another bin, the laptop does not turn on, it just blinks orange in charging port. I try to write backup, but again the laptop blinks orange. The welding is fine because I have tried many times, I have tried with another chip but no solution. I check its ic has 3.3 v. Please help me

Also something, at the beginning I programmed the chip with Bin to 15 g6, later I made a backup and when I put the charger on the laptop, the orange light flashes -
Hello,
if you somehow manage to go back to the starting point / restore original bios and make it work as it worked before, on HP Zbook G5 sound card in windows actually doesn't work if you disable from bios some intel features - I believe it was IME - intel management engine but could be something similar. I wasted a day trying to fix audio then a simple bios option flip fixed it.
Btw, windowsupdate just pulled bios 1.29.1.0 and bricked my zbook, I am writing this from my old laptop
Please make sure flashing firmwares is dissalowed in bios to keep your laptop alive.

Hi how are you thanks for reply ... I don't know what happened, but 2 such boards that had audio problems when I programmed the bios incorrectly did not turn on even after I wrote backup again. I will try again with a clean bios, maybe I have a solutionComment

Hi arber1232,
For me it was somewhere in bios that I disabled ability of OS to access ME (management engine). Turned out that audio driver needs ME.
My laptop is not with me so I cannot provide an exact option to enabke/disable or a screenshot.
Try to find it or wait till I get my laptop back please.

Hello,
update from my side, I received a replacement laptop as BIOS issue was not possible to be fixed by flashing.
There are indeed options in bios to control Intel ME but in this replacement options look different and I don't see the options I originally found to be affecting audio on windows so I cannot make a screenshot.
I did not dare to provision ME as it requires me to change the default 'admin' password and I am afraid I might in the future forget to what I changed it and lock myself out of the bios/ME.
For sure, there was an option which sounded like a 'intel AMT or ME interface towards OS' and when that was disabled, audio did not work at all.
Hope you solve your issue. I will mind my own business of trying not to brick this one.
Thank you,

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Good morning and delighted to be part of this community, I have purchased an old business laptop, a HP ZBook 17 G5 system model with the Intel(R) Xeon(R) E-2176M CPU @ 2.70GHz, 2712 Mhz, 6 main processors, 12 logical processors, BIOS version and date HP Q70 BIOS version and date Ver. 01.29.01, 09/24/2024 SMBIOS version 3.1, the BIOS is password locked, I cannot access the BIOS to change parameters, my question is if in this model the BIOS can be unlocked without having to open the laptop or on the contrary, do you have to solder or something? Thank you very much -
Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
