Sony Vaio VPCEB24FX No power on

[crdz66]

Hello Friends.
I have a Sony Vaio Laptop with no power on.

The Adapter show me 19.5v and the connector to the motherboard too.
I check couple ic (8 legs) and the output read the same (19.5v)
Just one, close to processor no read nothing.

The computer show amber light as soon is connected to the adapter but, When I try turn on nothing happened (no fan spin, very little activity(led blinking less 2 secs).

Do you think I have a short on some component?
Do I need to make reflow?

Any idea can help me.

Thanks Friends.

first, give the code of motherboard. So we can find a schematic. Since it is vpceb series, it should be mbx-224. You have to make sure your bios is ok. Re-flash or change ic with new one has the dump in it. Dont Reflow anything yet.

Sound like southbridge to me? Had the problem before, southbridge was shorted, check for shorts on the motherboard after you checked the bios.
