Hi masters, can anyone help me to clean ME? I tried that with no success (ME analyzer, found right ME, use ME to to inplement it, nothing works) . Finally unit did not start at all, I had to flash back back ups... PCH has been shorted, so I replaced it, need to clean it. Maybe there is other problem with board, but I think ME region problem. Many thanks

Hello, I have an HP EliteOne 800 G6 that I believe has some issues with the BIOS. The computer has entered a boot loop, and the only things it shows are the HP logo followed by an HP BIOS update message, and then everything starts over. I cannot enter the BIOS since, as I mentioned, only these two screens keep repeating.
I managed to dump the BIOS file, so if someone could look at what the issue is or if you have a different BIOS file that I could test.
Thank you for your help!

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

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

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...
