Hello,
sorry for my bad english. I have a Problem with a 320-3115-B. It has a green light on the charger but wont turn on. I measured the powerrails and noticed, that PP3V42_G3H is 3,62V. I thought that my multimeter could be a little of but PPBUS_G3H is exakt 12,60V. This board had waterdamage but looks very clean overall. I also noticed, that PP3V3_S0 is there but most other S0 rails like PP1V5_S0, PP1V8_S0 or PP1V05_S0 are missing. These are all shorted to groung and i can not find where the short is. Another thing that i noticed is that U1800 is getting a little warm. Means this, that U1800 is shorting the S0 rails to ground or is it only still reciving power anr trying to work? The last and strangest thing i noticed is, that it makes a silent beeping sound in the U1800 areea if its getting power. It sonds like a damaged HDD with a litle click every second. I tryed to attach the sound file to this post (.m4a/.mp3) but it says invalid file. I´m not sure if this file is needed but if i can provide it.
Is there any hope to save this board or is it already dead?
Thank you for your help.
Best regards,
Felix
