The main reason I found the forums is because my SP3 started just going black. It works most of the time if plugged in. Battery says 95% charged, but pull the plug and the screen goes black. It was recommended on a PC webpage that I make myself known so MS will know how widespread the problem is. Thanks for any info on the forums or the computer! I've had computers since 1984, and this is the worse computer problem I have had. And I really like the SP3.
