I notice you've said its separated a bit, are you sure the rest of the case isn't slightly warped so part of the metal layer on the inside of the case is touching the circuit board? >>I don't know if this is related, but the lid seems to be separating along >>the seam on the bottom right side (facing the screen) by the hinge. > >Hmm - has there been any damage?

Actually, that orange blinky power light indicates any situation where there is a power problem, such as the 5V rail dipping due to excess current draw. For instance, if you short out a certain data line on the docking connector (which for some reason doesn't seem to have a buffer resistor on it) whilst its high, the laptop will do a panic shutdown (not even a hibernation) and flash that blinky thingy (I did that a few times when I touched the wrong pin on the docking connector when looking for the PS/2 ports) ... so it could be the shorting of ANY line or component that can supply more current than the tripoff threshold really. I'd imagine several of the lines that go to the LCD inverter would carry more than enough current to trip that emergency shutoff if it were shorted to ground. - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
