Good Evening,
I have a Gateway MA2-6520gz that will not power up. No lights, fan, or any other signs of life with either the battery or AC adapter.
I tried the reset (holding the on/off switch down, etc) to no avail. The power brick shows proper output when measured with my meter.
I disassembled the laptop and removed the motherboard. I checked for power going through the power-in jack and get the same reading as from the adapter.
One of the oddities of this board is that I cannot find a fuse anywhere. Any ideas on that?
Also, I have tried to test the little on/off switch but with uncertain results. I checked using the Ohm scale for resistance between the two pins that I think are for the switch. It shows an open circuit. The result does not change when I push the switch in while holding the leads on the pins. Still indicates an open circuit (I think). Is that the proper way to check the switch. I did that with the ac adapter unplugged from the MB.
Finally, what would be the proper way to check for power at the battery terminals? When I check those terminals should I be checking for AC or DC current?
Oh, the final finally - does anyone where I might locate a schematic for this model? The motherboard ID seems to be DAOMA2MB6D8.
Any help or appropriate suggestions will be greatly appreciated.
Regards,
Bill
