if you see no voltage then either one of the mosfets may be blocking it, so check the input of the first mosfet, its marked yellow in the picture.If you see fluctuating voltage like 17v then 20 then 15 then 19 and so on, if the voltage is fluctuating for more than 1 volt, then your power brick may be the culprit, if yes then check the power bricks output port with your multimeter, middle pin is 19v and the outer metal part is ground.If there is 19 volt then your first 2 mosfets have not failed and the fault lies in deeper in the motherboard, if you dont see 19 v then: Possible Solution(s): check if there is 19 volt after the 2nd Mosfet, see picture for where to place red probe of your Multimeter A Picture of the first 2 Mosfets from the acer aspire v3-772g motherboard
