Intro:
While troubleshooting a Mac Pro(6,1) referenced above I discovered the +5v secondary supply did not stand up on the D500-B graphics card as a result of a missing enable signal. The +3.3v secondary rail was the only rail that did standup. I tried to perform...12-07-2023, 09:55 PM -
Hello Everyone,
I need your help, maybe you have know where to buy a replacement.
I have a NM-D562 laptop motherboard that has a burned 0.75_ALW converter. (the layers and the pins also burned so i dont want to restore it but i need a replacement)
I have checked with lab power supply output (0.77V) laptop works, so i need a DC-DC module that can do its job.
According to schematic datasheet what i need on 0.75V_ALW:
Vout=0.75V±37.5mV
Vset=0.752V±1.46%
Vref=0.6V
TDC=4A
OCP=9.5A TYP=10.5A MAX
OVP=(1.15~1.25)*Vout
UVP=(0.6~0.7)*Vout... -
Hi guys have a HP 14 Labtop. DA0PAHMB8F0 .There is no White LED on the DC Jack .It got a drop of water damage right next to the 3V IC ( Silergy SY8386BRHC) and corroded a resistor and a pad which belongs to the Enable for the IC. I cleaned the area and re-soldered the resistor. Nothing Changed. I don't know what the value for the resistor should be.It measures about 80.0K No schematics available for this model. A good friend on here mon2 helped me identify the IC markings and gave good advice on making sure to measure the input voltages and enables and checking for short.
There is no short... -
