I have a Gateway Laptop MT3423 (I have had nothing but trouble since I bought it 2+ years ago). It shut down on me and then I was not able to turn it back on. I have tried the trick where you remove the battery and unplug, hold the power button down for 30 sec and then plug it back and and turn it back on. That worked about 3 times. When I try to turn it on, the lights start up like it is going to boot and then the lights fade (you can see them very dimly) and then nothing happens. The monitor doesn't even flicker. Any advice? The warranty is up also.

Sounds like a power problem. Inspect the motherboard under a magnifying glass. look for any bad solder joints, especially around the battery plug area and the power jack area. It sounds like a connection is failing under load. If you fins abad solder joint, then repair it.

One side of the DC circuit is failing. If it is a MA2 or MA3 it is most likely a MOSFET on the front end, (4814/4816/4916). Also check with a charged and known good battery
