Hi,
The laptop seems to have a corrupted bios (orange light blinking).
I found a bios from another post that is working (without correct informations)
I tried following the guides to clean ME region still doesn't work, so i guess i have something else to do but i'm a bit lost, so here i am.
Laptop infos :
Name : HP ProBook 650 G2
Serial : 5CG6350NCR
Model number ? : Y3B06ET#ABF
I don't know if the bios is locked, but i guess, once i have a working one, i could just use RCUnlocker to remove it.
Attached is a dump of the bios.
Thanks in advance for your helpComment

Hi everyone, this laptop boots to a black screen. I've already tested the RAM, and it's not the fault. Based on the measurements, the fault is in the BIOS ROM. Any help is appreciated.

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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.

Dear All,
Hope that this post is at the right place of the forum.
I am seeking help and technical advice to remove bios admin password from HP ProBook 4520s.
The laptop is operating normally and, I am not facing any major issue with it except; the bios admin password that I found about by coincidence only few weeks back.
As the laptop is operating normally, I am reluctant to take it to a workshop to de-solder the bios chip in order to read it by an external programmer, as I am not an expert in doing such a thing.

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
