Dear technicians,
When I measure SMD Mosfets on Laptop mainboards, I face shorted Mosfets sometimes. But I think it might be possible that I made some of them shorted by my measurements. Specifically, I measure resistance between pins of Mosfet while power is being applied to the mosfet and the mainboard. Is that possible this measurement make mosfet shorted?
For example: I measured 91 ohms between gate and source of a Mosfet while the mainboard was powered on. The next time I powered on that mainboard, I measured 0 ohm between gate and source of the same Mosfet. So, I think I made it shorted.
note: I measure Mosfets using my multimeter either in Diode mode or in Resistance mode.
thanks
