how do you check if a mosfet is in short,

This question is best posted in the laptop repair side of the forum.

Remove all power -> meter in resistance mode (start with the lowest scale).

Then measure across the mosfet pins as follows:

source (1-2-3) & drain (5-6-7-8)
source (1-2-3) & gate (4)
gate (4) & drain (5-6-7-8)

If the meter shows '1' -> switch to the next higher meter scale.

Post each measure & the meter scale used for the measurement.

You are checking for a low resistance reading which often means a defective mosfet.
