The Notebook Diagnostic Card itself only requires a 25-pin parellel printer port and usb port/cable. It is not necessary to install memory chips to perform analysis. “POST Codes” can be displayed through the hexadecimal display panel. Not all laptops display post codes through the printer port - some use a miniPCI slot. Check with your laptop manufacturer to be sure. Is it the CMOS battery or the memory? Or maybe the processor is toast? And how about the external cache? The Debug card will tell you instantly through a series of hexidecimal codes.
