    HP ProBook 440 G3 what happen?

    hi everyone ?

    HP ProBook 440 G3 DA0X61MB6G0
    problem is black screen with consumption 0.4 to 0.8 Amp on PSU

    i open the laptop i try to power up the laptop again from Pwrbtn Pins but suddenly the laptop dead

    short on 3.3v rail
    i inject 2v on 3.3v rail and the cpu becomes hot and a lot of components shorted around the cpu
    is that means the cpu is gone and what is the cause of this damage? .

      CPU dead. I've seen quite a bunch of these boards with dead CPUs, including replacement ones straight from HP...

              Lowest possible resistance on laptop motherboard rail - Guide Table request
              by Nagy Daniel
              Hi, I'm Daniel, and I'm new to the world of repairing motherboards.

              I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.

              I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.

              So, I generated a table with AI so I can...
