Hello all,
Bumping this thread rather than create a new one as I have pretty much the same problem: I have a D7830 that won't boot. On start the 3 leds at the top flash, the power LED lights, The fans spin consistently (no stepping down in speed) but nothing comes on the monitor and the keys have no affect (caps lock, num lock etc do not come on with the led indicators above the keyboard).
When on the mains adapter the battery does take a charge (no idea how much) and I can power on from the battery alone, but no change (still wont boot). Have tried with power adapter alone, with an external keyboard, external monitor, changed the ram etc, no change, however if I remove the ATI Radeon 9000 card the laptops monitor does come on but it's just a dull white screen with nothing else.
Perhaps more tellingly I have also tried starting with no ram, then with no CPU installed, then with both removed, to see if I at least get motherboard error beeps, but the exact same thing happens: Fans spin, power is there, but nothing else is happening. Evidently whatever is causing this won't even get the motherboard to beep on what should be primary errors?
Can't think of anything else I can try (short of buying a new motherboard) so asking if any users with previous experience of the problem ever found a fix for it.
