I have a T2984 which will not boot up. I opened up the T2984 and shorted across the switch but confirmed that is not it. What confuses me is that there is a green LED that is lit on the mobo when the power supply is plugged in. Is that telling me that the power supply is good, but that because the mobo is bad, I cannot start up? I am not sure, as I have heard that there are multiple output levels from a power supply. Perhaps the 3.3v is working, and the 12v is not?
I do not have a replacement power supply (only some older ones without the square 4 pin connector), as I am considering simply upgrading to a new system. I was hoping to make an informed decision about whether to buy a new power supply or not.
Thanks for any advice you might have!
