    I've searched the 'net (to include the owner's manual) but I can't find a description of where the screen sensor is on my 1530.

    When I power my computer on the fan starts up and the blue power indicator on the front of the laptop turn on, but the power light on the power button does not stay on more than a second, the hard drive indicator does not come on, and the screen backlight does not start. However, when I leave the laptop on the wrist rest and touchpad areas get hot, suggesting to me the HDD is spinning. I've run the laptop to my TV via the HDMI out and the TV shows a solid black screen.

    I haven't pulled the RAM yet, but I would think that if the HDD or RAM were bad I'd at least get a blinking cursor on the screen. And no backlight suggests the screen or the cable running the signal to the laptop screen has died, but then I would get a picture on my TV if that were the issue.

    So my last thought is the sensor that detects when the lid is closed is stuck and needs to be reset. If someone could help me figure out where that sensor is I'd greatly appreciate it!

    The "screen sensor" you're talking about is two parts: a magnet somewhere in the display assembly and a sensor under the palmrest. I think it's a fairly simple switch, and there's basically no way for it to be forced on (unless you place a magnet strategically on the palmrest, etc).

    I'm guessing your video card is gone. Try testing the machine on an external display.
