I'll try lifting the Vcc pin on the board tomorrow. The board does have a DEBUG_CON connector right next to the Flash chip which I suspect ties in, but as it has very fine connections and I have yet to find anyone that has made a cable to connect let alone reverse engineered the pinout, it won't do me any good. I suppose if all else fails, I can try removing the chip from the board. Thanks for suggestion!<br>

All power from the board has been removed (AC, Main Battery, CMOS<br>

I'm looking for any suggestions as to what I may be doing wrong. If I<br></div>

I missed this in my first read.<br>

I suspect that your laptop board does not have the proper isolation on the 3.3V supply. You have to power the SPI part only without powering the rest of the motherboard for ICP to work.<div><div></div><div class="h5"><br>
