Hello everyone, I am looking for help as I am struggling to remove lost BIOS Admin password on an HP EliteDesk G6 800 series desktop. I wanted to reset the vPro remote control IP kvm for homelab use.
Here is the hardware identification specs:

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 am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello guys,
I stupidly tried to read out my BIOS & EC flash (with a clamp). This didn't work, I only read FF's. But after this operation, the PC is not longer turning on, just beeps 5 times (and blinks red) then 2 times (blinks white). The manual says this is the error code for: "The embedded controller cannot find valid firmware.".
I think it locked itself because of my experiment. Is this fixable? I now removed both chips from the board and dumped them, I attach the files in this post hoping someone can help me fix my stupid error. Thanks so much in advance anyone... -
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...
