Hi friend, thanks for responding. The board turns on and off from its power button. When I connect the regulated power supply, the LED blinks several times and then turns off. If I press the power button, the board turns on. If I press the power button, it turns off, but the LED on the connector stays off. I haven't found any shorts, and the voltages (5V, 3V, and 19V) are stable when it's on.
I look forward to your comments.
Greetings from Colombia....

Good morning, I hope you can see the video of the failure, I'll share some videos with you, and yes, I've already tried removing the BIOS battery and the failure continues.

HP PROBOOK 450 G1 - LED flashing on the charging connector
Please, someone who can help me with a PROBOOK 450 G1. When I connect the charger or power supply, the power jack LED starts blinking. The board has the main voltages: 19V, 3V, 5V, and 3V, and the power button.
The board turns on.
This is the board model: Rampage_MB 12241-1 -
