The computer will run off a cahrged battery but not off the power supply. the supply is good. i traced the power to a mosfet new the power plug. it seems the mosfet is not coming on. i do not know where the signal to the gate comes from. also is this mosfet just a switch or is it being used as a regulator? i wnat to jump across it and see if the computer will run but do not want to fry the computer.
Well, what is the condition? Is it under warranty? If so, get it done with Gateway. If not, what you can do is buy a brand new jack online for this laptop. It may take some digging, but they exist new. Don’t buy a used part, though. The new is about as much as used in most cases. Here is the part you need.
