EC_RST# is not explicitly labelled on this schematic because the platform uses the eSPI bus, and the reset for the Embedded Controller (EC) is provided via ESPI_RST#, which comes directly from the PCH.
As I still can't find the ESPI_RST# - I have checked the line that comes before and HWPG comes before ECRST.
HWPG is not present. No short on that line.
Any advice, please.

Problem with PANASONIC CF53 laptop after changing BIOS settings

by AquaMan Ua

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

TONGFANG "GM7TG7P" Bios Password Problem?

by traxformania

Hello,

I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

I'm trying to reset my bios without success.

I tried :

-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting

by macabook
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

NEC VersaPro PC-VRT42FBFR22B BIOS problem

by trouble55

Hi All,

[Mother board model]
V-VE212(U3E1)

[Serial number]
24000135PA

[BIOS chip model]
Macronix MX77L12850F

I am having some problems with the BIOS of my Versapro PC-VRT42FBFR22B.

I extracted the BIOS file (versapro001.bin 16MB) from PC-VRT42FBFR22B ROM (MX77L12850F) using CH341A and NeoProgrammer V2.2.0.10, but I don't know how to remove the BIOS password, so I can't open the BIOS even if I boot with F2.

I also downloaded the BIOS update package (933A0400.zip) for PC-VRT42FBFR22B from the official...
