Hi Everyone
I own an HP Probook 440 G8 Laptop with a motherboard DAX8QAMB8D0 Rev-D. After connecting it, the laptop draws only 0,007 amps (refer to the picture below) and the lights begin to blink (see image). I’m unsure what might be causing this issue, possibly related to the BIOS settings I don’t fully understand. I’d really appreciate any advice you can offer.

Well, your voltage should ideally be around 19.5-21v according to the specifications, though I'm not certain that's the main issue even though it could be. Power verification checks often come across as more demanding on laptop boards compared to desktop ones. Have you considered using a higher input voltage? I'd suggest trying 19.5 or 20v just in case your power supply has any fluctuations. If that doesn't help, without a solid power signal the board won't draw much current. Also, it would be helpful to get a clearer picture of what's happening since it seems like the CPU or cooler might not be visible but it's still unclear.
