Vostro 3401 strange problem charge

[the Benninger]

Now the one offering apologies is me, I was working on the bottom side, when I looked at this part that you pointed out, I noticed the marker that is above PQ1 and not in PL3. The aggravating factor is that it was on the inductive coil PL301 on the bottom side, regarding the resistor PR1=33.2 ohms on my multimeter

the measurements of PQ1 are

Source/Drain= 65.2k
Source/Gate= 12.48k
Gate/Drain= 73.5k

[the Benninger]

I have no way of knowing if pq1 is good or not so I have made the decision to change it, while the resistance PR1 is at its correct value, which leads me to think that it is pq1 that causes the source to disassemble when reconnecting.
If you have anything else to add, I would be grateful; if not, we will just wait for the arrival of the components.

These are very low resistance readings for a good mosfet:

Source/Drain= 65.2k
Source/Gate= 12.48k
Gate/Drain= 73.5k

Each should be hundreds of k ohms or higher. One reason could be the influence of other parts on the part so best to remove and then test the same mosfet while it is on your workbench. If the resistance readings remain low, the part is indeed defective. Curious on the measurements of this mosfet that has been removed.

disassembled or out of the motherboard the readings were as follows

Source/Drain=72k
Source/Gate = 750M
Gate/Drain = 1050M

Reverse the meter leads and test source / drain but to me, this part is defective from the low resistance.

Source/Drain=72k

happy start of the week
something happens that I don't know if it's normal, when the reading started (38Mhom) it increased until it reached 60Mhom, in a span of 1 minute. I think it would have continued to increase if I hadn't lost connection. It's difficult to keep the test probes on the pins when it's disassembled due to the shape and size.
