    Acer Nitro shorted PCH doesnt Boot an517-52

    Hello, after changed the shorted PCH Hm470 the Notebook have good value in the cool. Blue light comes on once U Press Power but nothing more Happening.

    It have before a short on one Cap near the ALC Soundchip. I fixed the shorted Cap.
    BIOS and EC BIOS are also new but still nothing Happening.
    CPU has No Short.
    Orderd a new alc295 can it BE that the Sound IC is Not good and thats why IT doesnt start.
    There is also Missing a inductor near the 19,5v Port but IT should still Boot without it.

      You have posted in the wrong forum. This should be in the laptop section.

            You can just de solder the sound IC and see if it posts. Sound IC is not needed for mb to post.
            However you have not shared any info about resistance to GND and voltage on all coils Neither you've shared the m/b markings-so simply not possible to suggest anything meaningfull.

              I removed the Sound IC but it didnt helped.
              It still draws only 0.028 amps and then after 20/30 Seconds IT Go to Zero.

              I decided to send it to a repair Shop to Change again the PCH.

              Board is a fh52m la-j891p rev 1a 2060 10750h
              Another Thing is PLH11 is Missing and i dont know IT should be there or Not.

              On shematics it there but the shematics is for 0.1 revesion.

              On Google Pictures all with 1A have it.

                Hello:

                I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


                I started on the ACER:

                Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
                All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

                I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...
