ASUSPRO B9440UA Liquid damage.

[Lukosiukas]

Hello, maybe someone could help me. I don't have any schematic for this model. Motherboard has minor liquid damage, only few resistors, Maybe some has this motherboard on hand and could measure some 5resistors resistances ? Thanks in advise.

2yrs later, still have this laptop, still want to fix it. Maybe someone around has one and could take a 1minute measure ?

Sadly, Repair Guide is the only thing i got for this model

See attached. It is a start.

These resistors are linked to an I2C temp sensor @ PU9000 (8 pin).

PR9001 = used to select the I2C address of the temp sensor.

I see, but i need values.
Can you provide this boardview?

Re: ASUSPRO B9440UA Liquid damage.

The boardview is locked to a paid sub.

Locate PU9000 = thermal sensor IC -> post the topside markings and we should be able to reverse engineer the values. Need to locate the datasheet of this sensor IC.

the ic is UP1905AMA8.

Datasheet is attached.

What is on the OTHER side of this PCB? These parts appear to be monitoring temp of that component.

on other side is those 4 resistors which values i need

Re: ASUSPRO B9440UA Liquid damage.

We see the resistors but what is on the OTHER (opposite) side of this logic board? This will help us to know what component is being monitored for the temp.

Nothing.
