I have a Dell e1705 (with nvidia 7800 video) that will not boot. When I hit the power button, the power light comes on for about 5 seconds, then goes out. That's all I get. No sound comes from the machine - no fan, no HD spinning.
This occurs with or without the HD in place - I figured I might get to the BIOS at least.
This occurs on AC power (with and without the battery in the machine) and on battery power. When I try on AC power with the battery in, after the power light goes out, the battery light will blink once.
I tried various DIMM configs - both, just one, neither, no difference.
NONE of the other lights on the machine light up at all.
What to do? New motherboard? Something less drastic? Thanks in advance for your thoughts.
