Lenovo V310-15ikb (REV: F DA0LV6MB6F0 Mainboard)

[skylander]

Hi Gentlemen,
I have a DA0LV6MB6F0 REV: F dead mainboard and it has interesting oscillation noise starting after connecting battery to the mainboard without pressing power on button!

Mainboard suddenly powered off itself while working on normal conditions and could not power on again.


Before doing test did the following connections:
Speakers: Disconnected
HDD: Disconnected
On Slot RAM: Disconnected (It has 4GB Onboard RAM)
CPU Fan: Connected
Charging Adapter: Disconnected
DVD ROM: Disconnected
CPU Cooling Pipes: Disconnected

I believe noise is coming nearby power mosfets on MB. There was no overtemperature situation when i check the components by touching the bodies while buzzing sound continues.

I have attached an audio file (OscillationBuzzing.mp3/zip) which is recorded while the battery is just connected to the MB.

How to troubleshoot the faulty component?
Could you please provide me more information??


thanks in advance
