Nm-a272 cpu start to heat if plug power adapter

[kalilinux25]

Hello I'm new here I have a certain problem my NM-A272 board start to heat the CPU if I plug the DC adapter it has a power indecator I have Check any short but no luck.
If any suggestion you have will be helpful , thanks in advance

What part of the cpu starts to heat?
Does the cpu vcore power come up?

Re: Nm-a272 cpu start to heat if plug power adapter

Yes ,Its present when I plug the ADAPTER but I have a short on the mother board but I cant find what it causing the short




how can I find the short?

How do know that you have a short?

i'VE CHECK THIS

THERE SHORTED TO GROUND

Remove them from mb and check out of circuit in diode mode for short-that will rest your doubt.

Those the short cause the cpu to heat ?

From the picture it is unclear where the short is. Red circles are around capacitors, those?
What do you call a short? How many ohms?
Low ohms readings on cpu vcore are normal.

When I use diode mode It beeps on both side

As khaak has said, its very true that there exists very low resistance eg 100ohms in vcore circuits, i too dont doubt anything wrong there. You can still try removing those 2 fets and test them out of circuit.

The two mosfets are done testing and there fine no problem even though I remove the two mosfet I get short to ground in capacitor and the two mosfet traces

short is resistance under 3ohm

[kalilinux25]

Re: Nm-a272 cpu start to heat if plug power adapter

Yes its definitely short

Re: Nm-a272 cpu start to heat if plug power adapter

remove coil and check on what side is short. than just continue to locate it
