Thank you for your response. The voltage measurement at point PL5301 shows 1.7V. According to the power sequence outlined on page 102, the next step would likely be to check the [B]PCH_DPWROK[/B] signal at resistor [B]R1745[/B], if I am not mistaken.Thank you for your response.

[B]Hello everyone,[/B]
My name is Rafaa, and I hold a degree in industrial computer engineering. I'm passionate about DIY and electronics, and I am currently starting to repair computer motherboards.
I have already downloaded several motherboard schematics from your site, and I really appreciate the help you provide to people trying to solve technical issues. I am always eager to learn, and specifically, I'm interested in how to remove a BIOS password using an existing file.
I hope to join this active community. I regularly work on motherboard repairs and...Leave a comment:
