Hello,
I got a HP Envy 27 AIO, Model No. 27-b153ng, with blocked, unknown password.
So i need to reset/delete the BIOS password, as i cannot access BIOS settings for a new install.
Am reading through the guides ( BIOS guides, methods, resources and tools)
and am working to extract BIOS via CH341A programmer.
To do that i need to desolder the Winbond 25Q64FVSIQ 64Mbit serial flash memory25Q64FVSIQ.
I cannot use the clamp clips to connect, as the SoC is too near and blocks access.
I was wondering if someone knows the function of the... -
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

Apologies if this is the wrong forum, but I'm not looking for a specific BIOS file, I'm trying to understand how one makes a clean BIOS file. So here's the background. I have 2 HP EliteDesk 800 g2 mini 35w pcs. One is working fine; the other doesn't have display out or working USB's nor does it have any flashing error lights. The CPU does get worm enough to cause the fan to spin up, so I think it's posting, but I just don't know. I had it working at one point but trouble started when I tried to put in a drive caddy that had a cooling fan on it. I thought it would be compatible but wasn't... -
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

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...
